DESCRIPTION
The P4C187/P4C187Lare 65, 536-bit ultra high speed static RAMs organized as 64K x 1. The CMOS memories require no clocks or refreshing and have equal access and cycle times. The RAMs operate from a single 5V ± 10% tolerance power supply. Data integrity is maintained for supply voltages down to 2.0V for the Low Power version, typically drawing 10µA.
Access times as fast as 10 nanoseconds...
