UPD431000A-X - 1M-BIT CMOS STATIC RAM 128K-WORD BY 8-BIT EXTENDED TEMPERATURE OPERATION

Download the UPD431000A-X datasheet PDF. This datasheet also covers the UPD variant, as both devices belong to the same 1m-bit cmos static ram 128k-word by 8-bit extended temperature operation family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key Features
