MR25H256CDCR

Memory IC Overview

The MR25H256CDCR is a non-volatile magnetoresistive random-access memory (MRAM) integrated circuit manufactured by Everspin Technologies. It features a storage capacity of 256 kilobits organized as 32K x 8 bits. The device utilizes a Serial Peripheral Interface (SPI) for data communication with a maximum clock frequency of 40 MHz. It operates within a supply voltage range of 2.7V to 3.6V and supports an industrial temperature range from -40°C to +85°C. The component is housed in an 8-lead Thin Dual Flat No-lead (TDFN) package measuring 5x6 mm with an exposed pad, designed for surface-mount technology applications.

Memory IC Feature Summary

• Non-volatile data retention utilizing magnetic tunnel junction technology without requiring power for storage
