AT29LV040A

1. 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 150 ns, and a low 54 mW power dissipation. When

the device is deselected, the CMOS standby current is less than 40 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 3-volt

only Flash memories.

To allow for simple in-system reprogrammability, the AT29LV040A does not require

high input voltages for programming. Three-volt-only commands determine the opera-

tion of the device. Reading data out of the device is similar to reading from an

EPROM. Reprogramming the AT29LV040A is performed on a sector basis; 256 bytes

of data are loaded into the device and then simultaneously programmed.

During a reprogram cycle, the address locations and 256 bytes of data are captured at

microprocessor speed and internally latched, freeing the address and data bus for

other operations. Following the initiation of a program cycle, the device will automati-

cally erase the sector and then program the latched data using an internal control

timer. The end of a program cycle can be detected by DATA polling of I/O7. Once the

end of a program cycle has been detected, a new access for a read or program can

begin.
