µ PD431000A
1M-BIT CMOS STATIC RAM 128K-WORD BY 8-BIT
Description
The µPD431000A is a high speed, low power, and 1,048,576 bits (131,072 words by 8 bits) CMOS static RAM. The µPD431000A 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 is packed in 32-pin PLASTIC DIP, 32-pin PLASTIC SOP and 32-pin PLASTIC TSOP (I) (8 × 13.4 mm) and (8 × 20 mm).
Features
