Description:

The Microchip Technology Inc. 24AA014H/24LC014H

is a 1 Kbit Serial Electrically Erasable PROM with

operation down to 1.7V. The device is organized as a

single block of 128 x 8-bit memory with a 2-wire serial

interface. Low-current design permits operation with

maximum standby and active currents of only 1 μA and

400 μA, respectively. The device has a page write

capability for up to 16 bytes of data. Functional address

lines allow the connection of up to eight 24AA014H/

24LC014H devices on the same bus for up to 8 Kbits of

contiguous EEPROM memory. The device is available

in the standard 8-pin PDIP, 8-pin SOIC (150 mil),

TSSOP, 2x3 TDFN and MSOP packages.

24AA014H/24LC014H 3.0 FUNCTIONAL DESCRIPTION 4.4 The 24AA014H/24LC014H supports a bidirectional, 2-wire bus and data transmission protocol. A device that sends data onto the bus is defined as transmitter, and a device receiving data as receiver. The bus has to be controlled by a master device that generates the Serial Clock (SCL), controls the bus access and generates the Start and Stop conditions while the 24AA014H/24LC014H works as slave.

PAGE 8
24AA014H/24LC014H 5.0 DEVICE ADDRESSING FIGURE 5-1: A control byte is the first byte received following the Start condition from the master device (Figure 5-1). The control byte consists of a four-bit control code; for the 24AA014H/24LC014H this is set as ‘1010’ binary for read and write operations. The next three bits of the control byte are the Chip Select bits (A2, A1, A0).
PAGE 9
24AA014H/24LC014H 6.0 WRITE OPERATIONS 6.1 Byte Write The higher order four bits of the word address remain constant. If the master should transmit more than 16 bytes prior to generating the Stop condition, the address counter will roll over and the previously received data will be overwritten. As with the byte write operation, once the Stop condition is received, an internal write cycle will begin (Figure 6-2).
PAGE 10
24AA014H/24LC014H 7.0 ACKNOWLEDGE POLLING FIGURE 7-1: Since the device will not acknowledge during a write cycle, this can be used to determine when the cycle is complete (this feature can be used to maximize bus throughput). Once the Stop condition for a write command has been issued from the master, the device initiates the internally-timed write cycle and ACK polling can be initiated immediately.
PAGE 11
24AA014H/24LC014H 8.0 READ OPERATIONS Read operations are initiated in the same way as write operations, with the exception that the R/W bit of the slave address is set to ‘1’. There are three basic types of read operations: current address read, random read and sequential read. 8.1 Current Address Read The 24AA014H/24LC014H contains an address counter that maintains the address of the last word accessed, internally incremented by one.
