Description
IS62WV102416EBLL-55BLI is a high-density static RAM device from ISSI (IS62WV family). It offers 1,024K × 16 organization, totaling 16 Mbits (about 2 MB) of storage. The -55 indicates a 55 ns access time. It is a parallel, asynchronous SRAM with a 16‑bit data bus, designed for fast random access and relatively low power. Typical supply is around 3.3 V (broadly 2.7–3.6 V for many IS62WV parts); there are commercial and industrial temperature variants—check the datasheet for exact ranges. Key features include standby when CE is high and straightforward OE/WE control for reads/writes. Applications include cache memory, frame buffers, graphics buffering, and other buffering roles in embedded systems requiring fast 16‑bit access. The EBLL packaging code denotes the specific mechanical/packaging variant. For exact pinout, electrical characteristics, timing diagrams, and ordering details, consult the ISSI IS62WV102416EBLL-55BLI datasheet.
Equivalent
I can provide exact cross-references, but I need details: what is the operating voltage (1.8V/2.5V/3.3V), package type (SOIC, TSOP, etc.), and the target density (16 Mb, i.e., 1M x 16). Once you confirm, I’ll list exact equivalents from Micron, Winbond, Cypress, Renesas, ISSI, etc.
