The UC62LV0256 is a high performance, very low power CMOS Static Random Access Memory organized as 32,768 words by 8 bits and operates from a wide range of 2.0V to 3.6V supply voltage. Advanced CMOS technology and circuit techniques provide both high speed and low power features with a typical CMOS standby current of 1uA and maximum access time of 70ns in 2.0V operation. Easy memory expansion is provided enable (CE), and active LOW output enable (OE) and three-state output drivers. The UC62LV0256 has an automatic power down feature, reducing the power consumption significantly when chip is deselected. The UC62LV0256 is available in the JEDEC standard 28 pin 330mil Plastic SOP, 300mil Plastic SOJ, 600mil Plastic DIP and 8mmx13.4mm TSOP (normal type).
The UC62LV0256 is a high‑performance, very low‑power CMOS static RAM organized as 32,768 words by 8 bits. It operates from a wide supply range and offers three‑state TTL‑compatible outputs, automatic power‑down when deselected, and data‑retention capability down to 1.2 V.
The datasheet provides electrical characteristics, pin descriptions, timing diagrams for read and write cycles, and ordering information for several package options (SOP‑28, SOJ‑28, DIP‑28, TSOP‑28). Temperature grades of -35 °C, -55 °C and -70 °C are supported.
