MR25H256CDFR

Memory IC Overview

The MR25H256CDFR is a 256-kbit Magnetoresistive Random Access Memory (MRAM) device manufactured by Everspin Technologies. It features a 32K x 8 organization and communicates via a Serial Peripheral Interface (SPI) with a clock frequency of 40 MHz. The component operates within a supply voltage range of 2.7 V to 3.6 V and supports surface mount installation in an 8-DFN (5x6 mm) package. It is designed for non-volatile data storage with a specified operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Utilizes magnetoresistive random access memory technology for non-volatile data retention without requiring power.
• Supports high-speed serial communication through a standard SPI interface compatible with various microcontrollers.
• Provides robust performance across industrial temperature ranges suitable for demanding electronic environments.

Memory IC Applications

• Data logging systems requiring persistent storage of operational parameters
• Parameter storage for efficient operation of electric powertrains
• Industrial control units needing reliable non-volatile memory

Memory IC Procurement Notes

Verify the specific suffix CDFR indicates the reel packaging format, as other suffixes may denote tray or cut tape options. Confirm the component status, as this series may be marked as not recommended for new designs depending on the manufacturing date code. Ensure compatibility with the target system's SPI protocol and voltage levels before integration.

Memory IC Selection Notes

Select this component when a non-volatile memory solution with high endurance and low power consumption is required. The 256-kbit capacity suits applications storing configuration data or small datasets. Verify that the 8-DFN package dimensions fit the printed circuit board layout constraints and that the SPI interface timing meets the system requirements.
