DESCRIPTION

The P4C163 and P4C163L are 73,728-bit ultra high-speed

static RAMs organized as 8K x 9. The CMOS memories re-

quire no clocks or refreshing and have equal access and

cycle times. Inputs are fully TTL-compatible. The RAMs op-

erate from a single 5V±10% tolerance power supply. With

battery backup, data integrity is maintained for supply volt-

ages down to 2.0V. Current drain is 10 µA from a 2.0V supply.

Access times as fast as 25 nanoseconds are available, per-

mitting greatly enhanced system operating speeds. CMOS

is used to reduce power consumption in both active and

standby modes.

The P4C163 and P4C163L are available in 28-pin 300 mil

DIP and SOJ and 28-pin 350 x 550 mil LCC packages provid-

ing excellent board level densities.
