DESCRIPTION
The P3C1021 is a 65,536 words by 16 bits high-speed
CMOS static RAM. The CMOS memory requires no
clocks or refreshing, and has equal access and cycle
times. Inputs are fully TTL-compatible. The RAM oper-
ates from a single 3.3V ± 0.3V tolerance power
supply.
Access times as fast as 10 nanoseconds permit greatly
enhanced system operating speeds. CMOS is utilized
to reduce power consumption to a low level. The P3C1021
is a member of a family of PACE RAM™ products offer-
ing fast access times.

The P3C1021 device provides asynchronous operation
with matching access and cycle times. Memory loca-
tions are specified on address pins A0 to A15. Reading is
accomplished by device selection (CE and output en-
abling (OE) while write enable (WE) remains HIGH. By
presenting the address under these conditions, the data
in the addressed memory location is presented on the
data input/output pins. The input/output pins stay in the
HIGH Z state when either CE or OE is HIGH or WE is
LOW.
Package options for the P3C1021 include 44-pin SOJ
and TSOP packages.
