Description
The AT29BV010A is a 2.7-volt only in-system Flash Programmable and Erasable Read Only Memory (Flash). Its 1 megabit of memory is organized as 131,072 words by 8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS EEPROM technol ogy, the device offers access times to 120 ns, and a low 54 mW power dissipation. When the device is deselected, the CMOS standby current is less than 50 µA. 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 Low Voltage Flash family of products.
To allow for simple in-system reprogrammability, the AT29BV010A does not require high input voltages for programming. The device can be operated with a single 2.7V to 3.6V supply. Reading data out of the device is similar to reading from an EPROM. Reprogramming the AT29BV010A is performed on a sector basis; 128 bytes of data are loaded into the device and then simultaneously programmed.
