Active9 in stock

Overview

The MX25V4035FM1I is a 4Mbit Serial NOR Flash memory featuring an SPI interface with Dual and Quad I/O capabilities. It operates on a wide voltage range from 2.3V to 3.6V and supports clock frequencies up to 108 MHz. Designed for efficiency, it offers a 512K x 8 organization and a low 1uA standby current, making it suitable for compact, battery-powered embedded designs.

Why Choose This Part

The component provides high-speed data throughput via Quad I/O mode while maintaining extremely low power consumption with a 1uA standby current. Its wide supply voltage range (2.3V to 3.6V) ensures compatibility with both legacy 3.3V systems and modern low-voltage microcontrollers.

Applications

Firmware Storage
Ideal for storing boot code and application firmware in resource-constrained IoT devices.
Parameter Logging
Used to store system configuration data and sensor calibration constants across power cycles.
Wearable Electronics
The low power consumption and small 8-SOP footprint suit space-limited wearable applications.

Getting Started

Integrate this flash IC using standard SPI drivers; most modern MCU HALs support the standard JEDEC ID and command set used by Macronix. When designing the PCB, ensure short traces for the 108 MHz clock and place a 0.1uF decoupling capacitor close to the VDD pin. For prototyping, the 8-SOP package can be mounted on a standard SOIC-8 to DIP adapter.
