BR62256F-70LL

The BR62256F-70LL is a 32768 word × 8 bit asynchronous high-speed CMOS static RAM. It runs on a 5V single

power supply, and in addition to its low power consumption and high-speed, its low standby current enables its use

in battery backup applications.

Applications

•

General-purpose

Features

•

1) SRAM with a 32768 word × 8 bit configuration.

2) High speed read access time of 70ns maximum (Ta

= 0 to 70°C).

5) Input / output TTL compatible.

6) Common input / output pin with three output status-

es.

3) Battery backup is possible.

7) No clock is necessary (asynchronous static circuit).

8) Input and output data are in the same phase.

9) Low power consumption.

Standby current: 50µA max. (Ta = 0 to 70°C)

Data holding current: 3µA max. (Ta = 0 to 70°C)

4) 5V single power supply voltage with ± 10% fluctua-

tion tolerance.
