Overview
DATA SHEET MOS INTEGRATED CIRCUIT 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 • 131,072 words by 8 bits organization • Fast access time: 70, 85, 100, 120, 150 ns (MAX.
