MX25R1635FZNIH0
Overview
The MX25R1635FZNIH0 is an ultra-low-power 16Mbit Serial NOR Flash memory featuring a wide operating voltage range from 1.65V to 3.6V. It supports Single, Dual, and Quad I/O SPI modes with a maximum clock frequency of 80 MHz in High Performance mode. This device is specifically engineered for power-sensitive applications where minimizing standby and deep power-down current is critical for battery longevity.
Why Choose This Part
The primary advantage is the dual-mode operation, allowing engineers to switch between Ultra Low Power and High Performance modes based on system needs. Its wide VCC range (1.65V to 3.6V) simplifies power tree design by allowing direct connection to various battery chemistries without additional regulation. The Quad I/O capability significantly increases data throughput compared to standard SPI flash while maintaining a small 8-WSON footprint.
Applications
Key Specifications
Getting Started
To interface with the MX25R1635FZNIH0, configure your MCU SPI peripheral for Mode 0 or Mode 3 and ensure the VCC matches your logic levels. Use standard NOR Flash driver libraries supporting the SFDP (Serial Flash Discoverable Parameters) standard to quickly implement read, erase, and program functions. For prototyping, ensure the 8-WSON (6x5mm) land pattern includes the exposed thermal pad connected to ground for mechanical stability.
