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

in excess of 10,000 times.
