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.

Notes:
1. Stresses greater than those listed under MAXIMUM RATINGS may
cause permanent damage to the device. This is a stress rating only
and functional operation of the device at these or any other conditions
above those indicated in the operational sections of this specification
is not implied. Exposure to MAXIMUM rating conditions for extended
periods may affect reliability.
2. Extended temperature operation guaranteed with 400 linear feet per
minute of air flow.
3. Transient inputs with V
IL
not more negative than –2.0V and
V
IH
≤
V
CC
+ 0.5V, are permissible for pulse widths up to 20 ns.
4. This parameter is sampled and not 100% tested.
5.
WE
is HIGH for READ cycle.
6.
CE
is LOW and
OE
is LOW for READ cycle.
7. ADDRESS must be valid prior to, or coincident with
CE
transition LOW.
8. Transition is measured ± 200 mV from steady state voltage prior to
change, with loading as specified in Figure 1. This parameter is
sampled and not 100% tested.
9. Read Cycle Time is measured from the last valid address to the first
transitioning address.
