Description

The AT29LV040A is a 3-volt only in-system Flash Programmable and Erasable Read

Only Memory (PEROM). Its 4 megabits of memory is organized as 524,288 words by

8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS EEPROM technology,

the device offers access times to 200 ns, and a low 54 mW power dissipation. When

the device is deselected, the CMOS standby current is less than 40=µA. The device
