P4C1024L

LOW POWER 128K x 8

CMOS STATIC RAM

locations are specified on address pins A

0 to A16. Read-

ing is accomplished by device selection (CE

1 low and

CE

2 high) and output enabling (OE) while write enable

(WE) remains HIGH. By presenting the address under

these conditions, the data in the addressed memory lo-

cation is presented on the data input/output pins. The

input/output pins stay in the HIGH Z state when either

CE

1 or OE is HIGH or WE or CE2 is LOW.

The P4C1024L is packaged in a 32-pin TSOP, 445 mil

SOP, and a 600 mil PDIP.

The P4C1024L is a 1,048,576-bit low power CMOS static

RAM organized as 128Kx8. The CMOS memory re-

quires no clocks or refreshing, and has equal access

and cycle times. Inputs are fully TTL-compatible. The

RAM operates from a single 5V±10% tolerance power

supply.

Access times of 55 ns and 70 ns are availale. CMOS is

utilized to reduce power consumption to a low level.

The P4C1024L device provides asynchronous opera-

tion with matching access and cycle times. Memory
