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
0 to A16. Read-
ing is accomplished by device selection (
1 low and
CE
2 high) and output enabling (
) while write enable
(
) 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.
