FEATURES
DESCRIPTION
The P4C1023L is a 1 Megabit low power CMOS static
RAM organized as 128K 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 of 55 ns and 70 ns are availale. CMOS is
utilized to reduce power consumption to a low level.
The P4C1023L 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 P4C1023L is packaged in a 32-pin 400 or 600 mil
ceramic DIP and in a 32-pin ceramic SOJ.

... See Figures 1 and 2 * including scope and test fixture. Note: Because of the high speed of the P4C1023L, care must be taken when testing this device; an inadequate setup can cause a normal function- ing part to be rejected as faulty. Long high-inductance leads that cause supply bounce must be avoided by bringing the V directly up to the contactor fingers. A 0.01 µ ...
