Description

The AT29C020 is a 5-volt-only in-system Flash programmable and erasable read only

memory (PEROM). Its 2 megabits of memory is organized as 262,144 bytes. Manu-

factured with Atmel’s advanced nonvolatile CMOS technology, the device offers ac-

cess times to 90 ns with power dissipation of just 220 mW over the commercial tem-

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

than 100 µA. Device endurance is such that any sector can typically be written to in

excess of 10,000 times.
