DESCRIPTIOn
The P4C1024L is a 1,048,576-bit low power CMOS static
RAM organized as 128Kx8. 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 of 55 ns, 70 ns, and 100 ns are available.
CMOS is utilized to reduce power consumption to a low
level.
The P4C1024L device provides asynchronous operation
with matching access and cycle times. Memory locations
are specified on address pins A
0
to A
16
. Reading is ac-
complished by device selection (CE
1
low and CE
2
high)
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
1
or
OE
is HIGH or
WE
or
CE
2
is LOW.
The P4C1024L is packaged in a 32-pin TSOP, 445 mil
SOP, 600 mil PDIP, or 32-pin LCC package.

notes:
1. WE is HIGH for READ cycle.
2.
CE

and
OE
are LOW, and CE
2
is HIGH for READ cycle.
3. ADDRESS must be valid prior to, or coincident with later of
CE
1
transi-
tion LOW or CE
2
transition HIGH.
4. 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.
5. READ Cycle Time is measured from the last valid address to the first
transitioning address.
