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.
