P4C1257
P4C1257
Pyramid Semiconductor
256K (256Kx1) CMOS SRAM
The P4C1257 is a 256K x 1-bit ultra high speed static RAMs. The CMOS memory requires no clock or refreshing and has equal access and cycle times. Inputs and outputs are fully TTL-compatible. The RAMs operates from a single 5V±10% tolerance power supply. Data integrity is maintained for supply voltages down to 2.0V, typically drawing 10 µA.
Access times as fast as 12 nanoseconds are available, greatly enhancing system speeds.
The P4C1257L are available in a 24-pin 300 mil DIP or SOJ, 28 pin LCC and flatpack packages, providing excellent board level densities.
