IS66WVE4M16EBLL-70BLI

IS66WVE4M16EBLL-70BLI is a 64Mb async/page PSRAM. It is an integrated memory device containing 64Mbit pseudo static random access memory using a self-refresh DRAM array organized as 4M words by 16bits. 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. It include the industry-standard, asynchronous memory interface found on other low-power SRAM or pseudo-SRAM (PSRAM) offerings. For seamless operation on an asynchronous memory bus, PSRAM products incorporated a transparent self-refresh mechanism. The hidden refresh requires no additional support from the system memory controller and has no significant impact on device read/write performance.
