DATA SHEET

MOS INTEGRATED CIRCUIT

μPD431000A-X

1M-BIT CMOS STATIC RAM

128K-WORD BY 8-BIT

EXTENDED TEMPERATURE OPERATION

Description

The μPD431000A-X is a high speed, low power, and 1,048,576 bits (131,072 words by 8 bits) CMOS static RAM.

The μPD431000A-X has two chip enable pins (/CE1, CE2) to extend the capacity. And battery backup is available.

In addition to this, A and B versions are low voltage operations.

The μPD431000A-X is packed in 32-pin PLASTIC SOP, 32-pin PLASTIC TSOP (I) (8 × 13.4 mm) and (8 × 20 mm).

Features

• 131,072 words by 8 bits organization

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

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

• Operating ambient temperature: TA = –25 to +85 °C

• Low VCC data retention: 2.0 V (MIN.)

• Output Enable input for easy application

• Two Chip Enable inputs: /CE1, CE2
