FEATURES
DESCRIPTION
The P4C1048L is a 4 Megabit low power CMOS static
RAM organized as 512K x 8. 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 as fast as 45 ns are availale. CMOS is
utilized to reduce power consumption to a low level.
The P4C1048L device provides asynchronous opera-
tion with matching access and cycle times. Memory

locations are specified on address pins A
ing is accomplished by device selection (CE low) and
output enabling (OE) while write enable (WE) remains
HIGH. By presenting the address under these condi-
tions, the data in the addressed memory location is pre-
sented on the data input/output pins. The input/output
pins stay in the HIGH Z state when either CE is HIGH or
WE is LOW.
The P4C1048L is packaged in a 32-pin 445 mil plastic
SOP, 32-pin TSOP II, or 600 mil plastic or ceramic side-
brazed DIP.
