IS42S32800J-7BLI

IS42S32800J-7BLI is a 32‑Mbit memory device from ISSI (Integrated Silicon Solution, Inc.). It is typically organized as 4M × 8, designed for high‑speed data buffering and caching in embedded systems. It operates from a single supply (commonly 3.3V) and uses a clocked, synchronous interface for reads and writes. The “-7” speed grade generally indicates around 70 ns typical access time, with timing governed by CLK, CE, WE, and OE signals. The “BLI” suffix usually denotes Pb‑free packaging with an industrial temperature range (e.g., −40°C to 85°C), though exact package and environmental specs vary by revision. Features often include synchronous burst or latched operations, tri‑state outputs, and standard memory‑controller compatibility. Applications include caches, frame buffers, DSP data paths, and other memory expansion needs in consumer, automotive, or industrial electronics. For precise electrical characteristics, timing diagrams, pinout, and packaging, consult the latest ISSI datasheet for IS42S32800J-7BLI. If you can share your target voltage, speed, and temperature range, I can tailor the overview further.
