DESCRIPTION
The P4C1024 is a 1,048,576-bit high-speed 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 15 nanoseconds permit greatly enhanced system operating speeds. CMOS is utilized to
reduce power consumption to a low level. The P4C1024
is a member of a family of PACE RAM™ products offering fast access times.

The P4C1024 device provides asynchronous operations
with matching access and cycle times. Memory locations 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.

Notes:
5.WE is HIGH for READ cycle.
6.CE1 is LOW, CE2 is HIGH and OE is LOW for READ cycle.
7.ADDRESS must be valid prior to, or coincident with CE1 transition
LOW and CE2 transition HIGH.
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.
Document # SRAM124 REV C
9.READ Cycle Time is measured from the last valid address to the first
transitioning address.
10. Transitions caused by a chip enable control have similar delays
irrespective of whether CE1 or CE2 causes them.

TIMING WAVEFORM OF WRITE Cycle No. 1 (WE Controlled)(11)
Notes:
11. CE1 and WE must be LOW, and CE2 HIGH for WRITE cycle.
12. OE is LOW for this WRITE cycle to show tWZ and tOW.
13. If CE1 goes HIGH, or CE2 goes LOW, simultaneously with WE HIGH,
the output remains in a high impedance state.

14. Write Cycle Time is measured from the last valid address to the first

Note:
Because of the ultra-high speed of the P4C1024, 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.
Document # SRAM124 REV C
To avoid signal reflections, proper termination must be used; for example, a 50Ω test environment should be terminated into a 50Ω load
with 1.73V (Thevenin Voltage) at the comparator input, and a 116Ω
resistor must be used in series with DOUT to match 166Ω (Thevenin
Resistance).
