PD43256B

256K-BIT CMOS STATIC RAM

32K-WORD BY 8-BIT

Description

The

PD43256B is a high speed, low power, and 262, 144 bits (32,768 words by 8 bits) CMOS static RAM.

Battery backup is available (L, LL, A, and B versions). And A and B versions are wide voltage operations.

The

PD43256B is packed in 28-pin plastic DIP, 28-pin plastic SOP and 28-pin plastic TSOP (I).

Features

• 32,768 words by 8 bits organization

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

• Wide voltage range (A version: V

= 3.0 to 5.5 V, B version: V

= 2.7 to 5.5 V)

• 2 V data retention

• OE input for easy application
