This datasheet introduces the CY7C024/0241 and CY7C025/0251 low-power CMOS 4K x 16/18 and 8K x 16/18 dual-port static RAMs
The CY7C024/0241 and CY7C025/0251 are low‑power CMOS dual‑port static RAMs available in 4 K × 16/18 and 8 K × 16/18 configurations. They provide true dual‑ported memory cells, on‑chip arbitration, semaphore and interrupt flags, and can be expanded to 32‑/36‑bit widths using a master/slave configuration.
The devices include separate control pins for each port (CE, OE, R/W, INT, SEM, BUSY, etc.), support automatic power‑down, and are offered in 84‑pin PLCC, 84‑pin lead‑free PLCC, 100‑pin lead‑free TQFP and 100‑pin TQFP packages. Electrical specifications such as 15 ns access time, 2.4 V HIGH output, 0.4 V LOW output and typical operating currents are provided in the datasheet.
| Access time | 15 ns |
|---|---|
| Typical operating current | 190 mA |
| Supply voltage range | -0.3 V to +7.0 V |
The devices have a high‑speed access time of 15 ns.
Each device includes eight semaphore latches for resource sharing.
They are offered in 84‑pin lead‑free PLCC, 84‑pin PLCC, 100‑pin lead‑free TQFP, and 100‑pin TQFP packages.
