PD431000A
1M-BIT CMOS STATIC RAM
128K-WORD BY 8-BIT
Description
The
μ
PD431000A is a high speed, low power, and 1,048,576 bits (131,072 words by 8 bits) CMOS static RAM.
The
μ
PD431000A 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
μ
PD431000A 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).
