PD442000A-X

2M-BIT CMOS STATIC RAM

256K-WORD BY 8-BIT

EXTENDED TEMPERATURE OPERATION

Description

The

PD442000A-X is a high speed, low power, 2,097,152 bits (262,144 words by 8 bits) CMOS static RAM.

The

PD442000A-X has two chip enable pins (/CE1, CE2) to extend the capacity. And battery backup is available.

The

PD442000A-X is packed in 32-pin PLASTIC TSOP (I) (Normal bent) and 32-pin PLASTIC TSOP (I) (Reverse

bent).
