IS62WV5128ALL/IS62WV5128BLL are high-performance CMOS static RAMs with high speed, low power, three-state outputs, industrial temperature and lead-free.
The IS62WV5128ALL and IS62WV5128BLL are 512 K × 8 ultra‑low‑power CMOS static RAM devices offering high‑speed access times of 55 ns and 70 ns respectively. They operate from a single supply voltage (1.65‑2.2 V for the ALL version, 2.5‑3.6 V for the BLL version) and feature a standby power consumption as low as 9 pW.
The devices are available in multiple package types, including 32‑pin TSOP, 32‑pin sTSOP, and 36‑pin mini‑BGA, and support both commercial (0 °C to +70 °C) and industrial (‑40 °C to +85 °C) temperature ranges. Detailed electrical characteristics, timing diagrams, and packaging dimensions are provided in the following sections.
