Product Summary

The MT45W4MW16PCGA-70IT is a high-speed CMOS PSRAM memory device developed for low-power, portable applications. The MT45W4MW16PCGA-70IT is a 64Mb DRAM core device, organized as 4 Meg x 16 bits. This device includes an industry-standard asynchronous memory interface found on other low-power SRAM or PSRAM offerings. For seamless operation on an asynchronous memory bus, MT45W4MW16PCGA-70IT incorporate 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.

Parametrics
