IC RAM 4MBIT SPI 40MHZ 8DFN

Manufacturer: Everspin Technologies Inc.

Categories: Memory

Quality Control: Learn More

The Everspin Technologies Inc. MR25H40VDFR is a 4Mbit Magnetoresistive RAM (MRAM) memory component featuring a Serial Peripheral Interface (SPI) with a 40 MHz clock frequency. This non-volatile RAM offers a 9 ns access time and a memory organization of 512K x 8. Designed for surface mount applications, it is housed in an 8-VDFN Exposed Pad package, specifically the 8-DFN-EP, Small Flag (5x6) variant. Operating within a 3V to 3.6V supply voltage range, this component is qualified to AEC-Q100 standards and rated for an automotive grade, with an operating temperature range of -40°C to 105°C (TA). Its characteristics make it suitable for applications in automotive systems, industrial control, and data logging where high reliability and non-volatility are critical.

Integrated Circuit FAQs

An integrated circuit (IC) is a semiconductor chip that contains transistors, resistors, capacitors, and other electronic components on a single silicon substrate. ICs are the foundation of modern electronics and power devices such as smartphones, computers, automotive systems, and industrial equipment.

Integrated circuits work by routing electrical signals through microscopic semiconductor components fabricated onto a silicon chip. Depending on the design, ICs can process, amplify, store, or control electronic data.
