DESCRIPTION
The P4C187/P4C187L are 65, 536-bit ultra high speed
static RAMs organized as 64K x 1. The CMOS memories
require no clocks or refreshing and have equal access and
cycle times. The RAMs operate from a single 5V ± 10%
tolerance power supply. Data integrity is maintained for sup-
ply voltages down to 2.0V, typically drawing 10µA.
Access times as fast as 10 nanoseconds are available,
greatly enhancing system speeds. CMOS reduces power
consumption to a low 743mW active, 193/83mW standby
for TTL/CMOS inputs and only 5.5 mW standby for the
P4C187L.
The P4C187/P4C187L are available in 22-pin 300 mil DIP,
24-pin 300 mil SOJ, 22-pin and 28-pin LCC packages pro-
viding excellent board level densities.
