DESCRIPTION
The P3C1024 is a 1,048,576-bit high-speed CMOS
static RAM organized as 128Kx8. The CMOS memory
requires no clocks or refreshing, and has equal access
and cycle times. Inputs are fully TTL-compatible. The
RAM operates from a single 3.3V 0.3V tolerance power
supply.
Access times of 20 nanoseconds permit greatly en-
hanced system operating speeds. CMOS is utilized to
reduce power consumption to a low level. The P3C1024
is a member of a family of PACE RAM™ products offer-
ing fast access times.
The P3C1024 device provides asynchronous opera-
tions with matching access and cycle times. Memory
locations are specified on address pins A to A . Read-
0
16
ing is accomplished by device selection ( low and
1
CE high) and output enabling ( ) while write enable
2
( ) 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
1 ^{or is HIGH or or CE}2 ^{is LOW.}
Package options for the P3C1024 include 32-pin 300
mil DIP and SOJ packages as well as 400 mil SOJ.
