Description
The AT29BV040A 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
