DESCRIPTIOn
The P4C1256 is a 262,144-bit high-speed CMOS static
RAM organized as 32K x 8. The CMOS memory requires
no clocks or refreshing, and has equal access and cycle
times. Inputs are fullyTTL-compatible. The RAM operates
from a single 5V±10% tolerance power supply.
Access times as fast as 12 nanoseconds permit greatly
enhanced system operating speeds. CMOS is utilized to
reduce power consumption to a low level. The P4C1256
is a member of a family of PACE RAM products offering
fast access times.
The P4C1256 devices provides asynchronous operation
with matching access and cycle times. Memory locations
are specified on address pinsA
0 to A14. Reading is accom-
plished by device selection (CE) and output enabling (OE)
while write enable (WE) remains HIGH. By presenting the
address under these conditions, the data in the addressed
memorylocationispresentedonthedata input/outputpins.
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 P4C1256 include 28-pin DIP, SOJ,
and TSOP packages. For military temperature range,
Ceramic DIP and LCC packages are available.
