Dual-Port Static RAM with Busy Flag

Data Sheet

FEATURES

INTRODUCTION

The UT7C138 and UT7C139 are high-speed radiation-

hardened CMOS 4K x 8 and 4K x 9 dual-port static RAMs.

Arbitration schemes are included on the UT7C138/139 to

handle situations when multiple processors access the same

memory location. Two ports provide independent,

asynchronous access for reads and writes to any location in

memory. The UT7C138/139 can be utilized as a stand-alone

32/36-Kbit dual-port static RAM or multiple devices can be

combined in order to function as a 16/18-bit or wider master/

slave dual-port static RAM. For applications that require

depth expansion, the BUSY pin is open-collector allowing

for wired OR circuit configuration. An M/S pin is provided

for implementing 16/18-bit or wider memory applications

without the need for separate master and slave devices or

additional discrete logic. Application areas include

interprocessor/multiprocessor designs, communications,

and status buffering.

45ns and 55ns maximum address access time

Asynchronous operation for compatibility with industry-

standard 4K x 8/9 dual-port static RAM

CMOS compatible inputs, TTL/CMOS compatible output

levels

Three-state bidirectional data bus

Low operating and standby current

Radiation-hardened process and design; total dose

irradiation testing to MIL-STD-883 Method 1019

- Total-dose: 1.0E6 rads(Si)

- Memory Cell LET threshold: 85 MeV-cm²/mg

- Latchup immune (LET >100 MeV-cm²/mg)

QML Q and QML V compliant part

Packaging options:

- 68-lead Flatpack

- 68-pin PGA

Each port has independent control pins: chip enable (CE),

read or write enable (R/W), and output enable ( OE). BUSY

signals that the port is trying to access the same location

currently being accessed by the other port.
