DESCRIPTION
The P3C101 1 is a 131,072 words by 16 bit s 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 P3C101 1
is a member of a family of P ACE RAM™ product s 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 A0 to A17. 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/O0-7 and BHE for I/O8-15) 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 P3C101 1 include 44-pin SOJ and
TSOP packages.
