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