The WS128K32V-XXX 128Kx32 3.3V SRAM MULTICHIP PACKAGE is a low power CMOS memory that supports a 3.3V power supply, has TTL compatible inputs and outputs, and has built-in decoupling capacitors and multiple ground pins for low noise operation.
The WS128K32V-XXX is a 128‑Kbit by 32‑bit SRAM offered by White Microelectronics. It features low‑power CMOS operation, TTL‑compatible I/O, and configurable organization (256K×16 or 512K×8). The device is supplied in several ceramic packages, including a 66‑pin hex‑in‑line (HIP) and 68‑lead quad flat packs.
The data sheet provides detailed electrical characteristics, absolute maximum ratings, timing diagrams for read and write cycles, and ordering information for commercial, industrial and military temperature grades. It also lists package dimensions and lead finish options.
