IS66WVS1M8BLL - 8Mb Serial RAM

Download the IS66WVS1M8BLL datasheet PDF. This datasheet also covers the IS66WVS1M8ALL variant, as both devices belong to the same 8mb serial ram family and are provided as variant models within a single manufacturer datasheet.

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.

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).
  • High Performance - Clock Rate: 33MHz(max) for normal read 104MHz(max) for fast read - Page Size: 1024 Byte - Configurable Wrapped Burst Length: 32 and 1024 (Default=1024) - Always Wrapped Burst Operation within page: - Drive Strength: 50 ohm.
  • Low Power Consumption - Single 1.65V to 1.95V Voltage Supply - S.
