The MX25L25645GM2I-08G from MXIC (Macronix) is a 256Mb (32MB) SPI NOR Flash memory chip in an 8-pin SOIC package, operating within a 2.7V–3.6V voltage range. Designed for applications with stringent requirements for performance, reliability, and power efficiency—such as industrial control, automotive electronics, IoT, and security systems—it combines high-speed data throughput, low-power operation, and flexible memory management to meet modern embedded needs for code storage, data logging, and Execute-In-Place (XIP) functionality.
As part of MXIC’s MXSMIO® series, it supports single/dual/quad SPI interfaces and is compatible with DTR (Double Transfer Rate) mode, achieving a maximum clock frequency of 133MHz and data transfer rates up to 532Mb/s in Quad SPI mode. With an industrial temperature range (-40°C to +85°C), endurance of 100,000 program/erase cycles, and data retention of 20 years, it ensures robust operation in harsh environments.

Technical Advantages in Embedded Systems
1. High-Speed Read & XIP Support
The chip’s 133MHz Quad SPI interface and XIP capability allow MCUs to execute code directly from Flash, eliminating RAM loading delays. This reduces read latency to under 8 clock cycles, accelerates system cold start to ≤50ms, and cuts MCU memory usage by 40%—ideal for real-time applications like industrial PLCs or ADAS sensor processing.
2. Industrial Reliability & Wide Temperature Tolerance
Built on 55nm charge trap technology, it operates stably from -40°C to 105°C, with ±8kV ESD protection and undervoltage detection. Its 20-year data retention and high endurance suit demanding environments such as factory floors or automotive modules.
3. Low-Power Modes for Energy-Sensitive Applications
Featuring multi-level power management—including standby (≤5μA) and deep power-down (≤1μA) modes—it supports battery-powered IoT devices (e.g., smart sensors). A ≤5μs wake-up time ensures rapid response from sleep states, extending portable device battery life from months to years.
4. Flexible Memory Architecture & Security
Supports 4KB sector, 32KB/64KB block, and full-chip erase, with a 256-byte page program buffer. Integrated write-protection latches and OTP (One-Time Programmable) secure areas prevent firmware tampering. Select models include an AES-256 co-processor for hardware-level data encryption in automotive or security systems.
5. Package Compatibility & Ease of Integration
The 8-SOIC package is pin-compatible with mainstream 256Mb SPI NOR Flash variants, enabling drop-in replacement. MXIC provides HAL driver examples for platforms like STM32 and NXP, along with support for Keil and IAR toolchains, simplifying hardware/software integration.
The MXIC (Macronix) MX25L25645GM2I-08G, with its 256Mb density, 133MHz Quad SPI interface, and industrial-grade reliability, serves as a cost-effective choice for embedded storage. Its balanced performance in Execute-In-Place (XIP) capability, power consumption control, and security protection makes it particularly suitable for applications requiring high-speed code execution and long-term data reliability. Through the localized services provided by its distributor, MANDU Technology, customers can further reduce integration risks and enhance product competitiveness.
