M67204E

4 K

9 CMOS Parallel FIFO Rad Tolerant

Introduction

The M67204E implement a first-in first-out algorithm,

featuring asynchronous read/write operations. The FULL

and EMPTY flags prevent data overflow and underflow.

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 TEMIC 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 without affecting the write pointer. This is very

useful for retransmitting data when an error is detected in

the system.

Using an array of eigh transistors (8 T) memory cell, the

M67204E combine an extremely low standby supply

current (typ = 1.0

µA)

with a fast access time at 40 ns

over the full temperature range. All versions offer battery

backup data retention capability with a typical power

consumption at less than 2

µW.

The M67204E is processed according to the methods of

the latest revision of the MIL STD 883 (class B or S), ESA

SCC 9000 and QML.
