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
operate from a single 5V±10% tolerance power supply.
With battery backup, data integrity is maintained for supply
voltages 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, 28-pin 350 x 550 mil LCC, and 28-pin
CERPACK packages providing excellent board level densi-
ties.
