M67201A/M67202A

512

9 & 1 K

9 CMOS Parallel FIFO

Introduction

The M67201A/202A 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 reset 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 and

fabricated with the state of the art 1.0

µm

lithography

named SCMOS, the M 67201A/202A combine an

extremely low standby supply current (typ = 1.0

µA)

with

a fast access time at 25 ns over the full temperature range.

All versions offer battery backup data retention capability

with a typical power consumption at less than 5

µW.

For military/space applications that demand superior

levels

performance

and

reliability

the

M 67201A/202A is processed according to the methods

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

and/or ESA SCC 9000.
