IS66WVE2M16ALL
IS67WVE2M16ALL
1.8V Core Async/Page PSRAM
Overview
The IS66WVE2M16ALL 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 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.
