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
Functional Block Diagram
are specified on address pins A0 to A16. Reading is accomplished by device selection (CE1 low and CE2 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 CE1 or OE is HIGH or WE
or CE2 is LOW.
The P4C1024L is packaged in a 32-pin TSOP, 445 mil
SOP, 600 mil PDIP, or 32-pin LCC package.

2.CE1 and OE are LOW, and CE2 is HIGH for READ cycle.
3.ADDRESS must be valid prior to, or coincident with later of CE1 transition LOW or CE2 transition HIGH.
4.Transition is measured ± 200 mV from steady state voltage prior to

and not 100% tested.
5.READ Cycle Time is measured from the last valid address to the first
transitioning address.

Notes:
6. CE1 and WE are LOW and CE2 is HIGH for WRITE cycle.
7. OE is LOW for this WRITE cycle to show tWZ and tOW.
8. If CE1 goes HIGH or CE2 goes LOW simultaneously with WE HIGH,
the output remains in a high impedance state

Note:
Because of the ultra-high speed of the P4C1024L, care must be taken
when testing this device; an inadequate setup can cause a normal functioning part to be rejected as faulty. Long high-inductance leads that cause
supply bounce must be avoided by bringing the VCC and ground planes
directly up to the contactor fingers. A 0.01 µF high frequency capacitor
is also required between VCC and ground. To avoid signal reflections,
proper termination must be used; for example, a 50Ω test environment
should be terminated into a 50Ω load with 1.77V (Thevenin Voltage) at
the comparator input, and a 589Ω resistor must be used in series with
DOUT to match 639Ω (Thevenin Resistance).
