Overview
P4C1981/P4C1981L, P4C1982/P4C1982L ULTRA HIGH SPEED 16K x 4 CMOS STATIC RAMS FEATURES Full CMOS, 6T Cell High Speed (Equal Access and Cycle Times) – 10/12/15/20/25 ns (Commercial) – 12/15/20/25/35 ns (Industrial) – 15/20/25/35/45 ns (Military) Low Power Operation (Commercial/Military) Output Enable and Dual Chip Enable Functions 5V ± 10% Power Supply Data Retention with 2.
0V Supply, 10 µA Typical Current (P4C1981L/1982L Military) Separate Inputs and Outputs – P4C1981/L Input Data at Outputs during Write – P4C1982/L Outputs in High Z during Write Fully TTL Compatible Inputs and Outputs Standard Pinout (JEDEC Approved) – 28-Pin 300 mil DIP, SOJ – 28-Pin 350 x 550 mil LCC – 28-Pin CERPACK DESCRIPTION The P4C1981/L and P4C1982/L are 65,536-bit (16Kx4) ultra high-speed static RAMs similar to the P4C198, but with separate data I/O pins.
The P4C1981/L feature a transparent write operation when OE is low; the outputs of the P4C1982/L are in high impedance during the write cycle.
All devices have low power standby modes.
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 typically 10 µA from 2.
0V supply.
Access times as fast as 10 nanoseconds are available, permitting greatly enhanced system operating speeds.
CMOS is used to reduce power consumption.
For the P4C1982L and P4C1981L, power is only 5.
5 mW standby with CMOS input levels.
The P4C1981/L and P4C1982/L are available in 28-pin 300 mil DIP and SOJ, 28-pin 350x550 mil LCC and a 28-pin CERPACK package providing excellent board level densities.
