Description

The AT29LV512 is a 3-volt-only in-system Flash programmable erasable read-only
memory (PEROM). Its 512K of memory is organized as 65,536 words by 8 bits. Man-
ufactured 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.
