Description

The AT29C010A is a 5-volt-only in-system Flash programmable and erasable read

only memory (PEROM). Its 1 megabit of memory is organized as 131,072 words by

8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device

offers access times to 70 ns with power dissipation of just 275 mW over the commer-

cial temperature range. When the device is deselected, the CMOS standby current is

1-Megabit

less than 100 µA. The device endurance is such that any sector can typically be written to in excess of 10,000 times. To allow for simple in-system reprogrammability, the AT29C010A does not require high input voltages for programming. Five-volt-only commands determine the operation of the device. Reading data out of the device is similar to reading from an EPROM. Reprogramming the AT29C010A is performed on a sector basis; 128 bytes of data are loaded into the device and then simultaneously programmed.
PAGE 3
AT29C010A The sector address must be valid during each high to low transition of WE (or CE). A0 to A6 specify the byte address within the sector. The bytes may be loaded in any order; sequential loading is not required. Once a programming operation has been initiated, and for the duration of tWC, a read operation will effectively be a polling operation. SOFTWARE DATA PROTECTION: A software controlled data protection feature is available on the AT29C010A.
PAGE 4
TOGGLE BIT: In addition to DATA polling the AT29C010A provides another method for determining the end of a program or erase cycle. During a program or erase operation, successive attempts to read data from the device will result in I/O6 toggling between one and zero. Once the program cycle has completed, I/O6 will stop toggling and valid data will be read. Examining the toggle bit may begin at any time during a program cycle.
