The EM641FT8V is a low power 512Kx8 SRAM chip produced by EMLSI. It is manufactured using a 0.15um full CMOS process technology and operates at a voltage of 4.5V~5.5V. It provides three-state output and is compatible with TTL level. It supports industrial temperature range.
The EM641FT8V series is a low‑power 512 K×8 static RAM fabricated with a 0.15 µm full‑CMOS process. It operates over an industrial temperature range (‑40 °C to 85 °C) and is supplied in a 32‑pin SOP package suitable for space‑constrained designs. The device features three‑state outputs, TTL compatibility, and a low data‑retention voltage for battery‑backed operation.
Key specifications include a typical access time of 45 ns (up to 70 ns depending on speed grade), supply voltage of 4.5 V–5.5 V, power dissipation up to 1 W, and input leakage currents of 1 µA. The part provides both CMOS and TTL standby currents and supports a range of timing parameters for read and write cycles.
