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

to A

. 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

is HIGH or

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.
