Overview

The IS66/67WVS4M8ALL/BLL are integrated memory device containing 32Mb Pseudo Static Random Access Memory using a self-refresh DRAM array organized as 4M words by 8 bits. The device supports SPI (Serial Peripheral Interface) & QPI (Quad Peripheral Interface) protocols, Very Low Signal Count (6 signal pins; CLK, CE#, and 4 SIOs), Hidden Refresh Operation, and Industrial temperature and Automotive A2 grade temperature. In-Band Reset is supported instead of dedicated RESET# pin, and minimum transferred data size is 8bit. PERFORMANCE SUMMARY.
