μPD43256B-X

256K-BIT CMOS STATIC RAM

32K-WORD BY 8-BIT

EXTENDED TEMPERATURE OPERATION

Description

The μPD43256B-X is a high speed, low power, and 262,144 bits (32,768 words by 8 bits) CMOS static RAM.

The μPD43256B-X is an extended-operating-temperature version of the μPD43256B (X version : TA = –25 to +85°C).

And A and B versions are low voltage operations. Battery backup is available.

The μPD43256B-X is packed in 28-pin PLASTIC TSOP (I) (8 x 13.4 mm).

Features

• 32,768 words by 8 bits organization

• Fast access time: 70, 85, 100, 120, 150 ns (MAX.)

• Operating ambient temperature: T^A= –25 to +85 °C

• Low voltage operation (A version: V^CC= 3.0 to 5.5 V, B version: VCC = 2.7 to 5.5 V)

• Low V^CCdata retention: 2.0 V (MIN.)

• /OE input for easy application
