Document # SRAM107 REV E
Revised March 2010
P4C168/P4C168L , P4C169, P4C170
ULTRA HIGH SPEED 4K x 4
STATIC CMOS RAMS
DESCRIPTION
The P4C168, P4C169 and P4C170 are a family of
16,384-bit ultra high-speed static RAMs organized as
4K x 4. All three devices have common input/output
ports.The P4C168 enters the standby mode when the
chip enable (CE) control goes HIGH; with CMOS input
levels, power consumption is only 83mW in this mode.
Both the P4C169 and the P4C170 offer a fast chip select
access time that is only 67% of the address access time.
In addition, the P4C170 includes an output enable (OE)
control to eliminate data bus contention.The RAMs oper-
ate from a single 5V ± 10% tolerance power supply.
FEATURES
Full CMOS, 6T Cell
High Speed (Equal Access and Cycle Times)
– 12/15/20/25/35ns (Commercial)
– 20/25/35/45/55/70ns (P4C168 Military)
Low Power Operation (Commercial)
– 715 mW Active
– 193 mW Standby (TTL Input) P4C168
– 83 mW Standby (CMOS Input) P4C168
Single 5V±10% Power Supply
Fully TTL Compatible, Common I/O Ports
Three Options
– P4C168 Low Power Standby Mode
– P4C169 Fast Chip Select Control
– P4C170 Fast Chip Select, Output Enable
Controls
Standard Pinout (JEDEC Approved)
– P4C168: 20-pin DIP, SOJ, LCC, SOIC,
CERPACK, and Flat Pack
– P4C169: 20-pin DIP and SOIC
– P4C170: 22-pin DIP
Access times as fast as 12 nanoseconds are available,
permitting greatly enhanced system operating speeds.
CMOS is used to reduce power consumption to a low
715 mW active, 193 mW standby.
TheP4C168andP4C169areavailablein20-pin(P4C170
in 22-pin) 300 mil DIP packages providing excellent
board level densities. The P4C168 is also available in
20-pin 300 mil SOIC, SOJ, CERPACK, and Flat Pack
packages.
The P4C169 is also available in a 20-pin 300 mil SOIC
package.
