DESCRIPTION
The P4C1024 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 5V±10% tolerance power
supply.
Access times of 15 nanoseconds permit greatly en-
hanced system operating speeds. CMOS is utilized to
reduce power consumption to a low level. The P4C1024
is a member of a family of PACE RAM™ products offer-
ing fast access times.
The P4C1024 device provides asynchronous opera-
tions with matching access and cycle times. Memory
locations are specified on address pins A0 to A16. Read-
ing is accomplished by device selection (CE low and
1
CE high) and output enabling (OE) while write enable
2
(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
1
or
OE
is
HIGH
or
WE
or
CE2
is
LOW.
Package options for the P4C1024 include 32-pin 300
mil DIP and SOJ packages as well as 400 mil SOJ.

4. Transition is measured ± 200 mV from steady state voltage
prior to change, with loading as specified in Figure1. This
parameter is sampled and not 100% tested.
5. READ Cycle Time is measured from the last valid address to
the first transitioning address.
