512K x 16 LOW VOLTAGE, ULTRA LOW POWER CMOS STATIC RAM
The IS62WV51216ALL and IS62WV51216BLL are 8‑Mbit static RAMs organized as 512 K words by 16 bits. They feature high‑speed access times (45 ns for ALL, 55 ns for BLL), ultra‑low power consumption (36 mW typical operating, 12 pW standby), and TTL‑compatible interface levels. The devices are available in 48‑pin mini‑BGA and 44‑pin TSOP packages and support industrial temperature ranges.
The datasheet provides detailed pin configurations, truth tables, absolute maximum ratings, DC electrical characteristics, power‑supply specifications, read‑cycle timing, and mechanical dimensions for both package types. It also includes AC test conditions and waveform diagrams to aid designers in integrating the memory into their systems.
