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% toler-

ance power supply. Data integrity is maintained for supply

voltages down to 2.0V for the Low Power version, 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.
