AT45DB161E 16-Mbit DataFlash (with Extra 512-Kbits), 2.3V or 2.5V Minimum SPI Serial Flash Memory DATASHEET Features Single 2.3V - 3.6V or 2.5V - 3.
Description The Adesto® AT45DB161E is a 2.3V or 2.5V minimum, serial-interface sequential access Flash memory ideally suited for a wide variety of digital voice, image, program code, and data storage applications. The AT45DB161E also supports the RapidS serial interface for applications requiring very high speed operation. Its 17,301,504 bits of memory are organized as 4,096 pages of 512 bytes or 528 bytes each.
Table 1-1. Pin Configurations Asserted State Type Low Input SCK Serial Clock: This pin is used to provide a clock to the device and is used to control the flow of data to and from the device. Command, address, and input data present on the SI pin is always latched on the rising edge of SCK, while output data on the SO pin is always clocked out on the falling edge of SCK. — Input SI Serial Input: The SI pin is used to shift data into the device.
2. Block Diagram Figure 2-1.
Memory Array To provide optimal flexibility, the AT45DB161E memory array is divided into three levels of granularity comprising of sectors, blocks, and pages. Figure 3-1, Memory Architecture Diagram illustrates the breakdown of each level and details the number of pages per sector and block. Program operations to the DataFlash can be done at the full page level or at the byte level (a variable number of bytes). The erase operations can be performed at the chip, sector, block, or page level. Figure 3-1.
4. Device Operation The device operation is controlled by instructions from the host processor. The list of instructions and their associated opcodes are contained in Table 15-1 on page 40 through Table 15-4 on page 41. A valid instruction starts with the falling edge of CS followed by the appropriate 8-bit opcode and the desired buffer or main memory address location.
5. Read Commands By specifying the appropriate opcode, data can be read from the main memory or from either one of the two SRAM data buffers. The DataFlash supports RapidS protocols for Mode 0 and Mode 3. Please see Section 25., Detailed Bit-level Read Waveforms: RapidS Mode 0/Mode 3 diagrams in this datasheet for details on the clock cycle sequences for each mode. 5.
A low-to-high transition on the CS pin will terminate the read operation and tri-state the output pin (SO). The maximum SCK frequency allowable for the Continuous Array Read is defined by the fCAR1 specification. The Continuous Array Read bypasses both data buffers and leaves the contents of the buffers unchanged. 5.3 Continuous Array Read (High Frequency Mode: 0Bh Opcode) This command can be used to read the main memory array sequentially at higher clock frequencies up to the maximum specified by fCAR1.
of the main memory array to read and the last 10 bits (BA9 - BA0) of the 22-bit address sequence specify the starting byte address within the page. To perform a Continuous Array Read using the binary page size (512 bytes), the opcode 01h must be clocked into the device followed by three address bytes (A20 - A0). Following the address bytes, additional clock pulses on the SCK pin will result in data being output on the SO pin.
6. Program and Erase Commands 6.1 Buffer Write Utilizing the Buffer Write command allows data clocked in from the SI pin to be written directly into either one of the SRAM data buffers. To load data into a buffer using the standard DataFlash buffer size (528 bytes), an opcode of 84h for Buffer 1 or 87h for Buffer 2 must be clocked into the device followed by three address bytes comprised of 14 dummy bits and 10 buffer address bits (BFA9 - BFA0).
When a low-to-high transition occurs on the CS pin, the device will program the data stored in the appropriate buffer into the specified page in the main memory. The page in main memory that is being programmed must have been previously erased using one of the erase commands (Page Erase, Block Erase, Sector Erase, or Chip Erase). The programming of the page is internally self-timed and should take place in a maximum time of tP.
buffer is reached, then the device will wrap around back to the beginning of the buffer. When using the binary page size, the page and buffer address bits correspond to a 21-bit logical address (A20-A0) in the main memory. After all data bytes have been clocked into the device, a low-to-high transition on the CS pin will start the program operation in which the device will program the data stored in Buffer 1 into the main memory array.
Table 6-1. 6.
Table 6-2. 6.
6.10 Program/Erase Suspend In some code and data storage applications, it may not be possible for the system to wait the milliseconds required for the Flash memory to complete a program or erase cycle. The Program/Erase Suspend command allows a program or erase operation in progress to a particular 128KB sector of the main memory array to be suspended so that other device operations can be performed.
Table 6-4.
6.11 Program/Erase Resume The Program/Erase Resume command allows a suspended program or erase operation to be resumed and continue where it left off. To perform a Program/Erase Resume, an opcode of D0h must be clocked into the device. No address bytes need to be clocked into the device, and any data clocked in after the opcode will be ignored. When the CS pin is deasserted, the program or erase operation currently suspended will be resumed within a time of tRES.
7. Sector Protection Two protection methods, hardware and software controlled, are provided for protection against inadvertent or erroneous program and erase cycles. The software controlled method relies on the use of software commands to enable and disable sector protection while the hardware controlled method employs the use of the Write Protect (WP) pin.
Figure 7-2. Disable Sector Protection CS SI 3Dh 2Ah 7Fh A9h Each transition represents eight bits 7.2 Hardware Controlled Protection Sectors specified for protection in the Sector Protection Register and the Sector Protection Register itself can be protected from program and erase operations by asserting the WP pin and keeping the pin in its asserted state. The Sector Protection Register and any sector specified for protection cannot be erased or programmed as long as the WP pin is asserted.
7.3 Sector Protection Register The nonvolatile Sector Protection Register specifies which sectors are to be protected or unprotected with either the software or hardware controlled protection methods. The Sector Protection Register contains 16 bytes of data, of which byte locations 0 through 15 contain values that specify whether Sectors 0 through 15 will be protected or unprotected. The Sector Protection Register is user modifiable and must be erased before it can be reprogrammed.
Figure 7-4. Erase Sector Protection Register CS SI 3Dh 2Ah 7Fh CFh Each transition represents eight bits 7.3.2 Program Sector Protection Register Once the Sector Protection Register has been erased, it can be reprogrammed using the Program Sector Protection Register command. To program the Sector Protection Register, a 4-byte command sequence of 3Dh, 2Ah, 7Fh, and FCh must be clocked into the device followed by 16 bytes of data corresponding to Sectors 0 through 15.
7.3.3 Read Sector Protection Register To read the Sector Protection Register, an opcode of 32h and three dummy bytes must be clocked into the device. After the last bit of the opcode and dummy bytes have been clocked in, any additional clock pulses on the SCK pin will result in the Sector Protection Register contents being output on the SO pin.
8. Security Features 8.1 Sector Lockdown The device incorporates a sector lockdown mechanism that allows each individual sector to be permanently locked so that it becomes read-only (ROM). This is useful for applications that require the ability to permanently protect a number of sectors against malicious attempts at altering program code or security information. Warning: Once a sector is locked down, it can never be erased or programmed, and it can never be unlocked.

Figure 8-3. Freeze Sector Lockdown CS SI 34h 55h AAh 40h Each transition represents eight bits 8.2 Security Register The device contains a specialized Security Register that can be used for purposes such as unique device serialization or locked key storage. The register is comprised of a total of 128 bytes that is divided into two portions. The first 64 bytes (byte locations 0 through 63) of the Security Register are allocated as a One-Time Programmable space.
Figure 8-4. Program Security Register CS SI 9Bh 00h 00h 00h Data n Data n+1 Data n+x Each transition represents eight bits 8.2.2 Reading the Security Register To read the Security Register, an opcode of 77h and three dummy bytes must be clocked into the device. After the last dummy bit has been clocked in, the contents of the Security Register can be clocked out on the SO pin.
9. Additional Commands 9.1 Main Memory Page to Buffer Transfer A page of data can be transferred from the main memory to either Buffer 1 or Buffer 2. To transfer a page of data using the standard DataFlash page size (528 bytes), an opcode of 53h for Buffer 1 or 55h for Buffer 2 must be clocked into the device followed by three address bytes comprised of two dummy bits, 12 page address bits (PA11 - PA0) which specify the page in main memory to be transferred, and 10 dummy bits.
program the data from the buffer back into same page of main memory. The operation is internally self-timed and should take place in a maximum time of tEP. During this time, the RDY/BUSY Status Register will indicate that the part is busy. If a sector is programmed or reprogrammed sequentially page by page and the possibility does not exist that there will be a page or pages of static data, then the programming algorithm shown in Figure 26-1 on page 61 is recommended.
Table 9-2. Status Register Format – Byte 2 Bit Name 7 RDY/BUS Y 6 Type( 1) Ready/Busy Status R RES Reserved for Future Use R 5 EPE Erase/Program Error R 4 RES Reserved for Future Use R 3 SLE Sector Lockdown Enabled R 2 PS2 Program Suspend Status (Buffer 2) R 1 PS1 Program Suspend Status (Buffer 1) R 0 ES Erase Suspend R Note: 1. R = Readable only 9.4.1 RDY/BUSY Bit Description 0 Device is busy with an internal operation. 1 Device is ready.
9.4.5 PAGE SIZE Bit The PAGE SIZE bit indicates whether the buffer size and the page size of the main memory array is configured for the “power of 2” binary page size (512 bytes) or the standard DataFlash page size (528 bytes). 9.4.6 EPE Bit The EPE bit indicates whether the last erase or program operation completed successfully or not. If at least one byte during the erase or program operation did not erase or program properly, then the EPE bit will be set to the Logic 1 state.
10. Deep Power-Down During normal operation, the device will be placed in the standby mode to consume less power as long as the CS pin remains deasserted and no internal operation is in progress. The Deep Power-Down command offers the ability to place the device into an even lower power consumption state called the Deep Power-Down mode.
10.1 Resume from Deep Power-Down In order to exit the Deep Power-Down mode and resume normal device operation, the Resume from Deep Power-Down command must be issued. The Resume from Deep Power-Down command is the only command that the device will recognize while in the Deep Power-Down mode. To resume from the Deep Power-Down mode, the CS pin must first be asserted and then the opcode ABh must be clocked into the device. Any additional data clocked into the device after the opcode will be ignored.
10.2 Ultra-Deep Power-Down The Ultra-Deep Power-Down mode allows the device to consume far less power compared to the standby and Deep Power-Down modes by shutting down additional internal circuitry. Since almost all active circuitry is shutdown in this mode to conserve power, the contents of the SRAM buffers cannot be maintained. Therefore, any data stored in the SRAM buffers will be lost once the device enters the Ultra-Deep Power-Down mode.
10.2.1 Exit Ultra-Deep Power-Down To exit from the Ultra-Deep Power-Down mode, the CS pin must simply be pulsed by asserting the CS pin, waiting the minimum necessary tCSLU time, and then deasserting the CS pin again. To facilitate simple software development, a dummy byte opcode can also be entered while the CS pin is being pulsed just as in a normal operation like the Program Suspend operation; the dummy byte opcode is simply ignored by the device in this case.
11. Buffer and Page Size Configuration The memory array of DataFlash devices is actually larger than other Serial Flash devices in that extra user-accessible bytes are provided in each page of the memory array. For the AT45DB161E, there are an extra 16 bytes of memory in each page for a total of an extra 64KB (512-Kbits) of user-accessible memory. Therefore, the device density is actually 16.5-Mbits instead of 16-Mbits.
12. Manufacturer and Device ID Read Identification information can be read from the device to enable systems to electronically query and identify the device while it is in the system. The identification method and the command opcode comply with the JEDEC Standard for “Manufacturer and Device ID Read Methodology for SPI Compatible Serial Interface Memory Devices”.

13. Software Reset In some applications, it may be necessary to prematurely terminate a program or erase cycle early rather than wait the hundreds of microseconds or milliseconds necessary for the program or erase operation to complete normally. The Software Reset command allows a program or erase operation in progress to be ended abruptly and returns the device to an idle state.
14. Operation Mode Summary The commands described previously can be grouped into four different categories to better describe which commands can be executed at what times. Group A commands consist of: 1. Main Memory Page Read 2. Continuous Array Read (SPI) 3. Read Sector Protection Register 4. Read Sector Lockdown Register 5. Read Security Register Group B commands consist of: 1. Page Erase 2. Block Erase 3. Sector Erase 4. Chip Erase 5. Main Memory Page to Buffer 1 (or 2) Transfer 6.

16. Power-On/Reset State When power is first applied to the device, or when recovering from a reset condition, the device will default to SPI Mode 3. In addition, the output pin (SO) will be in a high impedance state, and a high-to-low transition on the CS pin will be required to start a valid instruction. The SPI mode (Mode 3 or Mode 0) will be automatically selected on every falling edge of CS by sampling the inactive clock state. 16.
17. System Considerations The serial interface is controlled by the Serial Clock (SCK), Serial Input (SI), and Chip Select (CS) pins. These signals must rise and fall monotonically and be free from noise. Excessive noise or ringing on these pins can be misinterpreted as multiple edges and cause improper operation of the device. PCB traces must be kept to a minimum distance or appropriately terminated to ensure proper operation.

21. Utilizing the RapidS Function To take advantage of the RapidS function's ability to operate at higher clock frequencies, a full clock cycle must be used to transmit data back and forth across the serial bus. The DataFlash is designed to always clock its data out on the falling edge of the SCK signal and clock data in on the rising edge of SCK.

22. AC Waveforms Four different timing waveforms are shown in Figure 22-1 through Figure 22-4. Waveform 1 shows the SCK signal being low when CS makes a high-to-low transition and Waveform 2 shows the SCK signal being high when CS makes a high-to-low transition. In both cases, output SO becomes valid while the SCK signal is still low (SCK low time is specified as tWL).
