DESCRIPTION
The P3C1011 is a 131,072 words by 16 bits high-speed
CMOS static RAM. The CMOS memory requires no
clocks or refreshing, and has equal access and cycle
times. Inputs are fully TTL-compatible. The RAM oper-
ates from a single 3.3V ± 0.3V tolerance power
supply.
Access times as fast as 10 nanoseconds permit greatly
enhanced system operating speeds. CMOS is utilized
to reduce power consumption to a low level. The P3C1011
is a member of a family of PACE RAM™ products offer-
ing fast access times.
The P3C1011 device provides asynchronous operation
with matching access and cycle times. Memory loca-
tions are specified on address pins A
0
to A
17
. Reading is
accomplished by device selection (CE and output en-
abling (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.
For both reading and writing, the Byte Enable control lines
(BLE for I/O
0-7
and
BHE
for I/O
8-15
) allow for the selection
of only 8 of the 16 I/O lines if desired. When a Byte
Enable control line is HIGH, the corresponding I/Os are
active.
Package options for the P3C1011 include 44-pin SOJ and
TSOP packages.
