PD442000L-X

2M-BIT CMOS STATIC RAM

256K-WORD BY 8-BIT

EXTENDED TEMPERATURE OPERATION

Description

The

PD442000L-X is a high speed, low power, 2,097,152 bits (262,144 words by 8 bits) CMOS static RAM.

The

PD442000L-X has two chip enable pins (/CE1, CE2) to extend the capacity. And battery backup is available.

B, C and D versions are low voltage versions.

The

PD442000L-X is packed in 32-pin plastic TSOP (I) (8

13.4 mm) and (8

20 mm).
