FEATURES
DESCRIPTION
The P4C1256 is a 262,144-bit high-speed CMOS
static RAM organized as 32Kx8. 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 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 prod-
ucts offering fast access times.
DIP (P5, C5, C5-1, D5-2), SOJ (J5), SOP (S11-1, S11-3)
CERPACK (F4) SIMILAR
See end of datasheet for LCC and TSOP
pin configurations.
The P4C1256 device provides asynchronous operation
with matching access and cycle times. Memory loca-
tions are specified on address pins A
to A
. Reading
is accomplished 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 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 P4C1256 include 28-pin 300
mil DIP, SOJ and TSOP packages. For military tempera-
ture range, Ceramic DIP and LCC packages are avail-
able.
