P4C188
P4C188
Pyramid Semiconductor
64K (16Kx4) CMOS SRAM with common I/O
The P4C188 and P4C188L are 65,536-bit ultra high speed static RAMs organised as 16K x 4. The CMOS memories require no clocks or refreshing and have equal access and cycle times. Inputs and outputs 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 typically 10µA from a 2.0V supply.
Access times as fast as 10 nanoseconds are available, permitting greatly enhanced system speeds. CMOS is utilised to reduce power consumption to a low 715mW active, 193mW standby and only 5mW in the P4C188L version.
The P4C188 and P4C188L are available in 22-pin 300 mil DIP, 24-pin 300 mil SOJ and 22-pin LCC packages providing excellent board level densities.
