This document mainly introduces the features of ISSI IS61LV256AL, including high-speed access time, automatic power-down, low power consumption, TTL compatible interface levels, single 3.3V power supply, full static operation, three-state outputs, etc.
This document describes the ISSI IS61LV256AL, a high‑speed, low‑power 32 K‑word by 8‑bit static RAM fabricated with ISSI's high‑performance CMOS technology. It details the device’s functional block diagram, pin assignments for both 28‑pin SOJ and TSOP packages, and the timing parameters for read and write cycles.
Key electrical characteristics include an 8 ns maximum access time, a single 3.3 V supply, typical standby power of 150 µW, and operation over commercial (0 °C to +70 °C) and industrial (‑40 °C to +85 °C) temperature ranges. Ordering information and mechanical packaging dimensions are also provided.
