DESCRIPTION
The P3C1041 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 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 P3C1041 device provides asynchronous operation
Functional Block Diagram
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 os HIGH or WE is LOW.
The P3C1041 is packaged in a 44-pin 400-mil wide TSOP
II package.

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 # SRAM130 REV B
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 P4C116/L, 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.
