General Description

The IS66/67WVS1M8ALL/BLL are integrated memory device containing 8Mb Pseudo Static Random Access Memory using a self-refresh DRAM array organized as 1M 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.

Overview

IS66WVS1M8ALL/BLL IS67WVS1M8ALL/BLL 8Mb SerialRAM 1.8V/3.0V, 104MHZ, SPI & QPI PROTOCOL 8Mb SerialRAM 1.8V/3.

Key Features

  • Industry Standard Serial Interface - SPI Protocol: 1-1-1 & 1-4-4 operation - QPI protocol: 4-4-4 operation - Low Signal Counts :6 Signal pins (CE#, CLK, SIO0~SIO3).
