Overview

Description

The MR25H256ACDF is a non-volatile magnetoresistive random-access memory (MRAM) device. It offers 256 kilobits of storage organized in a 32K x 8-bit configuration. MRAM technology combines the speed of SRAM with the non-volatility of Flash memory, allowing it to retain data without power. The device operates over a wide voltage range and provides fast read and write capabilities, typically with no delay between operations due to its non-volatile nature.
Key features of the MR25H256ACDF include a high-speed SPI interface, low power consumption, and virtually unlimited read/write endurance, making it suitable for applications requiring fast, frequent data access and storage. The MRAM is housed in a small package, making it ideal for space-constrained applications.
The MR25H256ACDF is commonly used in applications such as data logging, industrial automation, and embedded systems where reliable and fast non-volatile memory is crucial. It combines the best characteristics of various memory technologies, offering durability, speed, and energy efficiency.

Pinout

The MR25H256ACDF is a 256-kilobit non-volatile magnetoresistive random-access memory (MRAM) device. It is typically housed in an 8-pin small outline integrated circuit (SOIC) package. The pin count for this device is 8. Here are the functions of each pin:
1. CS# (Chip Select): Activates the device when low.
2. SO (Serial Output): Outputs data from the device and serves as the serial data output pin.
3. WP# (Write Protect): Protects part or all of the memory array from write operations.
4. VSS (Ground): Ground reference for the device.
5. SI (Serial Input): Serial data input pin for inputting data to the device.
6. SCK (Serial Clock): Provides the clock signal for the SPI bus.
7. HOLD#: Pauses the serial communication without deselecting the device.
8. VDD (Power Supply): Positive power supply for the device.
The MR25H256ACDF uses an SPI (Serial Peripheral Interface) protocol for communication, making it suitable for applications requiring fast and reliable non-volatile memory.
