Description

The M672061H implements a first-in first-out algorithm, featuring asynchronous

read/write operations. The FULL and EMPTY flags prevent data overflow and under-

flow. The Expansion logic allows unlimited expansion in word size and depth with no

timing penalties. Twin address pointers automatically generate internal read and write

addresses, and no external address information are required for the Atmel FIFOs.

Address pointers are automatically incremented with the write pin and read pin. The 9

bits wide data are used in data communications applications where a parity bit for

error checking is necessary. The Retransmit pin resets the Read pointer to zero with-

out affecting the write pointer. This is very useful for retransmitting data when an error

is detected in the system.

Using an array of eight transistors (8T) memory cell, the M672061H combines an

extremely low standby supply current (typ = 0.1 µA) with a fast access time at 15 ns

over the full temperature range. All versions offer battery backup data retention capa-

bility with a typical power consumption at less than 2 µW.

For military/space applications that demand superior levels of performance and reli-

ability the M672061H is processed according to the methods of the latest revision of

the MIL PRF 38535 (Q and V) or ESCC 9000.
