Description
The AT29C040A is a 5-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 up to 100 ns, and a low 220 mW power dissipation.
When the device is deselected, the CMOS standby current is less than 100
μ
A. The
device endurance is such that any sector can typically be written to in excess of
10,000 times. The programming algorithm is compatible with other devices in Atmel’s
5-volt-only Flash family.
