Overview

The IS66WVE1M16ALL is an integrated memory device containing 16Mbit Pseudo Static Random Access

Memory using a self-refresh DRAM array organized as 1M words by 16 bits. The device includes several

power saving modes : Partial Array Refresh mode where data is retained in a portion of the array and

Deep Power Down mode. Both these modes reduce standby current drain. 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.
