Description
The AT29LV256 is a 3-volt-only in-system Flash Programmable Erasable Read Only
Memory (PEROM). Its 256K of memory is organized as 32,768 words by 8 bits.
Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers
access times to 200 ns with power dissipation of just 54 mW over the commercial
temperature range. When the device is deselected, the CMOS standby current is less
than 20
μ
A. The device endurance is such that any sector can typically be written to
in excess of 10,000 times.
