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 mA 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 to a low 715 mW active, 193 mW standby. For the P4C1982L and P4C1981L, power is only 5.5 mW standby with CMOS input levels. The P4C1981/L and P4C1982/L are members of a family of PACE RAM™ products offering fast access times.

The P4C1981/L and P4C1982/L are available in 28-pin 300 mil DIP and SOJ, and in 28-pin 350x550 mil LCC packages providing excellent board level densities.
