DESCRIPTION

The TC51WHM516AXBN is a 33,554,432-bit pseudo static random access memory(PSRAM) organized as 2,097,152 words by 16 bits. Using Toshiba’s CMOS technology and advanced circuit techniques, it provides high density, high speed and low power. The device operates single power supply. The device also features SRAM-like W/R timing whereby the device is controlled by CE1 , OE , and WE on asynchronous. The device has the page access operation. Page size is 8 words. The device also supports deep power-down mode, realizing low-power standby.
