The EV2A16A MRAM (magnetoresistive random-access memory) is an extended-reliability version of the MR2A16A from Freescale Semiconductor. This 4Mbit device is available with full operational performance across the entire military temperature range (-55 to +125°C), for avionic-, defence- and aerospace-application requirements. The solution is engineered to help protect the data when unexpected events occur - such as a power loss- without the need of an external battery back-up. The device operates at SRAM speeds with symmetrical 35ns read and write cycles. It comes in a standard 44-lead TSOP type II package, with a standard SRAM interface for seamless system integration.
