IDT70V24S/L is a high-speed 3.3V 4K x 16 dual-port static RAM produced by IDT. Its features are true dual-port memory cells that allow simultaneous reads of the same memory location. It has high-speed access, low power consumption, expandable data bus width, and busy flag and interrupt flag.
The IDT70V24S/L is a 4 K × 16 dual‑port static RAM offering true dual‑ported memory cells, high‑speed access (15‑55 ns) and low‑power operation. It is available in 84‑pin PGA, 84‑pin PLCC and 100‑pin TQFP packages and supports both commercial and industrial temperature ranges.
The device includes on‑chip arbitration logic, semaphore signaling, and separate upper‑byte/lower‑byte control for multiplexed bus compatibility. Detailed electrical characteristics, timing diagrams, and semaphore operation are provided for system designers.
