The MT45W4MW16PFA-85 WT is a 64Mb asynchronous/page mode memory device from Quarktwin Technology Ltd., featuring a 4 Meg x 16 configuration. It operates with a voltage range of 1.70V to 1.95V for VCC and 1.70V to 3.30V for VCCQ. The device offers random access times of 85ns and supports low power consumption modes, with an asynchronous read current of less than 25mA and a standby current of 120µA, which can be reduced to 100µA in low-power mode. The memory supports a page mode read access with a page size of sixteen words, allowing for intrapage read access times of 25ns. It includes features such as temperature-compensated refresh, partial-array refresh, and deep power-down mode, making it suitable for applications requiring low power and efficient memory management. However, it is noted that this part is not recommended for new designs.
