P4C198

Pyramid Semiconductor

64K (16Kx4) CMOS SRAM with common I/O and OE

The P4C198/L and P4C198A/L are 65,536-bit ultra high-speed static RAMs organised as 16K x 4. Each device features an active low Output Enable control to eliminate data bus contention. The P4C198/L also have an active low Chip Enable (the P4C198A/L have two Chip Enables, both active low) for easy system expansion. The CMOS memories require 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. Data integrity is maintained with supply voltages down to 2.0V. Current drain is typically 10 µA from a 2.0V supply.

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.

The P4C198/L and P4C198A/L are available in 24-pin 300 mil DIP and SOJ, and 28-pin 350 x 550 mil LCC packages providing excellent board level densities.
