IS66WVD2M16DALL
32Mb Async and Burst CellularRAM 2.0
Overview
The IS66WVD2M16DALL is an integrated memory device containing 32Mbit Pseudo Static Random
Access Memory using a self-refresh DRAM array organized as 2M words by 16 bits. The device uses a
multiplexed address and data bus scheme to minimize pins and includes a industry standard burst
mode for increased read and write bandwidth. The device includes several power saving modes :
Reduced Array Refresh mode where data is retained in a portion of the array and Temperature
Controlled Refresh. Both these modes reduce standby current drain. The device can be operated in a
standard asynchronous mode and high performance burst mode. The die has separate power rails,
VDDQ and VSSQ for the I/O to be run from a separate power supply from the device core.
