P4C150 is a 4096-bit ultra high-speed static RAM organized as 1K x 4 for high speed cache applications. It features a reset control, requires no clocks or refreshing, and has equal access and cycle times. It operates from a single 5V ± 10% power supply and provides access times as fast as 10 nanoseconds for enhanced system operating speeds.
The P4C150 static RAM provides ultra‑high speed access times as low as 10 ns (commercial) and 15 ns (military) with a reset function that clears all words within two cycle times. It operates from a single 5 V ±10 % supply, requires no clock or refresh, and features fully TTL‑compatible inputs and outputs.
The device is offered in several JEDEC‑approved packages, including 24‑pin DIP, 24‑pin SOIC, 28‑pin LCC, and 24‑pin FLATPACK, covering both commercial (0 °C to 70 °C) and military (–55 °C to +125 °C) temperature ranges. Detailed electrical characteristics, timing diagrams, and ordering information are provided for design integration.
