DESCRIPTION
The P4C164 is a 65,536-bit ultra high-speed static RAM
organized as 8K x 8. 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. With
battery backup, data integrity is maintained with supply
voltages down to 2.0V. Current drain is typically 10 µA
from a 2.0V supply.
FUNCTIONAL BLOCK DIAGRAM
Access times as fast as 8 nanoseconds are available,
permitting greatly enhanced system operating speeds.
The P4C164 is available in 28-pin 300 mil DIP and SOJ, 28-
pin 600 mil plastic and ceramic DIP, 28-pin 350 x 550 mil
LCC, 32-pin 450 x 550 mil LCC, and 28-pin CERPACK.
The 70ns and 100ns P4C164s are available in the 600 mil
plastic DIP.
PIN CONFIGURATIONS
DIP (P5, P6, C5, C5-1, D5-1, D5-2),
SOJ (J5), CERPACK (F4), SOP(S6)
