AT28C010 Military

Description

The AT28C010 is a high-performance Electrically Erasable and Programmable Read Only Mem-

ory. Its one megabit of memory is organized as 131,072 words by 8 bits. Manufactured with

Atmel’s advanced nonvolatile CMOS technology, the device offers access times to 120 ns with

power dissipation of just 440 mW. When the device is deselected, the CMOS standby current is

less than 300

μA.

The AT28C010 is accessed like a Static RAM for the read or write cycle without the need for

external components. The device contains a 128-byte page register to allow writing of up to 128-

bytes simultaneously. During a write cycle, the address and 1 to 128-bytes of data are internally

latched, freeing the address and data bus for other operations. Following the initiation of a write

cycle, the device will automatically write the latched data using an internal control timer. The end

of a write cycle can be detected by DATA POLLING of I/O7. Once the end of a write cycle has

been detected a new access for a read or write can begin.

Atmel's 28C010 has additional features to ensure high quality and manufacturability. The device

utilizes internal error correction for extended endurance and improved data retention character-

istics. An optional software data protection mechanism is available to guard against inadvertent

writes. The device also includes an extra 128-bytes of EEPROM for device identification or

tracking.
