Description

The AT29LV010A is a 3-volt only in-system Flash programmable and erasable read

only memory (Flash). Its 1 megabit of memory is organized as 131,072 bytes by 8 bits.

Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers

access times to 120 ns with power dissipation of just 54 mW over the commercial tem-

perature range. When the device is deselected, the CMOS standby current is less

than 40 µA. The device endurance is such that any sector can typically be written to in

excess of 10,000 times.

PAGE 2
To allow for simple in-system reprogrammability, the AT29LV010A does not require high input voltages for programming. Three-volt-only commands determine the operation of the device. Reading data out of the device is similar to reading from an EPROM. Reprogramming the AT29LV010A is performed on a sector basis; 128 bytes of data are loaded into the device and then simultaneously programmed.
PAGE 3
AT29LV010A After the software data protection’s 3-byte command code is given, a byte load is performed by applying a low pulse on the WE or CE input with CE or WE low (respectively) and OE high. The address is latched on the falling edge of CE or WE, whichever occurs last. The data is latched by the first rising edge of CE or WE. The 128 bytes of data must be loaded into each sector. Any byte that is not loaded during the programming of its sector will be erased to read FFh.
PAGE 4
OPTIONAL CHIP ERASE MODE: The entire device can be erased by using a 6-byte software code. Please see Software Chip Erase application note for details. BOOT BLOCK PROGRAMMING LOCKOUT: The AT29LV010A has two designated memory blocks that have a programming lockout feature. This feature prevents programming of data in the designated block once the feature has been enabled. Each of these blocks consists of 8K bytes; the programming lockout feature can be set independently for either block.
