MR25H10 - Everspin Technologies

MR25H10 1Mb Serial SPI MRAM

An active low chip select for the serial MRAM. When chip select is high, the memory is powered down to minimize standby power, inputs are ignored and the serial output pin is Hi-Z. Multiple serial memories can share a common set of data pins by using a unique chip select for each memory. The data output pin is driven during a read operation and remains Hi-Z .
