Overview

The MX25R4035FZUIL0 is a 4Mbit Serial NOR Flash memory featuring a wide supply voltage range of 1.65V to 3.6V. It supports Single, Dual, and Quad I/O SPI modes and is specifically designed with a dual-tier power architecture that includes an Ultra Low Power mode and a High Performance mode. This versatility allows engineers to optimize for either minimal current draw (2.8mA) or high-speed data throughput (up to 108MHz in High Performance mode).

Why Choose This Part

This memory IC offers exceptional flexibility with its 1.65V to 3.6V operating range, allowing it to interface directly with low-voltage SoCs without level shifters. The dual-mode architecture provides a unique trade-off between power consumption and speed, while the 8-USON (2x3mm) package minimizes PCB footprint. Reliability is ensured through 100,000 program/erase cycles and 20-year data retention.

Applications

Wearable Electronics
Ideal for fitness trackers and smartwatches where ultra-low standby current (5uA Deep Power-down) is critical for battery longevity.
IoT Sensor Nodes
Provides non-volatile storage for sensor logs and firmware updates in power-constrained remote environments.
Portable Medical Devices
Suitable for handheld diagnostic tools requiring small footprint 8-USON packaging and secure data storage.
Battery-Powered Consumer Tech
Efficiently handles boot code storage for low-power microcontrollers in mobile accessories.

Getting Started

When integrating this part, use the Ultra Low Power mode for battery-constrained operations or switch to High Performance mode via internal registers for fast firmware execution. Engineers should ensure SPI Mode 0 or 3 is configured on the host MCU and utilize the 4KB sector architecture for efficient flash management. Evaluation is commonly done using standard SPI flash programmers or by connecting the 8-USON pads to a logic analyzer for timing verification.
