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.
