Macronix MX25L25635FMI-10G – 256Mb Serial NOR Flash Memory
The MX25L25635FMI-10G from Macronix International is a high-performance 256Mb (32MB) Serial NOR Flash memory designed for embedded systems requiring fast read operations and reliable non-volatile storage. It features a standard SPI (Serial Peripheral Interface) with Dual/Quad I/O support, enabling flexible integration with microcontrollers and SoCs. Operating at a wide voltage range (2.7V–3.6V) and supporting clock frequencies up to 104MHz, this device ensures efficient data access for high-speed applications. Its 10ns page access time and uniform 4KB sector architecture make it ideal for firmware storage, boot code, and real-time execution (XIP). The chip comes in an 8-pin SOP (150mil) package, offering a compact footprint for space-constrained designs.
FLASH - NOR Memory IC Key Features
The MX25L25635FMI-10G provides advanced security and reliability features, including individual sector protection (4KB sectors), block locking, and OTP (One-Time Programmable) security registers. It supports Quad I/O (QSPI) mode, significantly boosting data transfer rates compared to standard SPI. The device includes Deep Power-Down mode (<1µA standby current) for ultra-low-power applications. Additional features include a program/erase endurance of 100,000 cycles and 20-year data retention, ensuring long-term reliability. Macronix’s proprietary Fast Read (FR) and Dual/Quad Output Read (DOR/QOR) commands further enhance performance, making it suitable for high-speed embedded systems.
Applications
This NOR Flash memory is widely used in consumer electronics, automotive infotainment, IoT devices, and industrial control systems. It is particularly well-suited for firmware storage in networking equipment, boot code execution in microcontrollers, and real-time OS (RTOS) applications. Its high-speed read performance makes it ideal for XIP (Execute-In-Place) implementations, reducing system latency. Automotive-grade variants (AEC-Q100 qualified) are available for ADAS, instrument clusters, and telematics, ensuring compliance with stringent automotive reliability standards.
Selection Advantages
Compared to parallel NOR Flash or NAND IC alternatives, the MX25L25635FMI-10G offers lower pin count, reduced PCB complexity, and better random access speeds. Its Quad SPI interface provides up to 4x faster data throughput than standard SPI, improving system responsiveness. The low-power operation extends battery life in portable devices, while hardware write protection prevents accidental data corruption. Macronix’s proven reliability in industrial and automotive markets ensures long-term supply stability, making this chip a dependable choice for mission-critical applications.
