DESCRIPTION
The P4C1041 device provides asynchronous operation
with matching access and cycle times. Memory locations are specified on address pins A0 to A17. Reading is
accomplished by device selection (CE 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 or OE is HIGH or WE is
LOW.
The P4C1041 is a 262,144 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 operates from a single 5.0V ± 10% 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 P4C1041
is a member of a family of PACE RAM™ products offering fast access times.
Package options for the P4C1041 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 VIL not more negative than –2.0V and
VIH ≤ VCC + 0.5V, are permissible for pulse widths up to 20 ns.
Document # SRAM133 REV OR
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.

Note:
Because of the ultra-high speed of the P4C1041, 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 1.73V
(Thevenin Voltage) at the comparator input, and a 116Ω resistor must
be used in series with DOUT to match 166Ω (Thevenin Resistance).
