Overview

Description

MX25U25635FMI-10G is Macronix’s 256-Mbit serial flash memory from the MX25U family. It provides non-volatile storage for firmware and data via an SPI-compatible interface.
Key points:
- Capacity: 256 Mbit (32 MB)
- Voltage: typically 2.7–3.6 V
- Interface: SPI serial flash (standard SPI; some variants support dual/quad I/O modes—see datasheet for this exact device)
- Organization: 4 KB sectors; 64 KB blocks (and larger erase options); 256-byte page programming
- Speed: fast read up to around 104 MHz clock
- Features: write enable, block/sector protection, security features, deep power-down and low-power standby
- Package: 8-pin (compact) with industrial temperature options
- Applications: boot code, firmware updates, code/data storage in MCUs and FPGAs
For exact timings, mode support (including Quad I/O), and electrical characteristics, consult the official datasheet for the -10G variant.

Package

8-pin SOP package (SOP-8 / US8).

Pinout

- Pin count: 8 pins (SOP-8 package)
- Function: 256-Mbit serial NOR flash memory (SPI interface) for non-volatile storage. Uses standard SPI signals (CS, CLK, DI/MOSI, DO/MISO) with WP and HOLD for write-protect/hold; supports typical flash operations (read, program, erase).

Manufacturer

- Manufacturer: Macronix International Corp., Ltd. (Macronix).
- Company type: Taiwan-based semiconductor company (an integrated device manufacturer, IDM) that designs, develops, and manufactures memory ICs (non-volatile memory such as NOR flash, MRAM, etc.) and related products.

Application

- 256-Mbit serial NOR flash with Quad SPI for fast boot and firmware storage
- Boot flash and code storage for microcontrollers/SoCs in embedded systems
- Data storage for embedded applications in industrial, automotive, and consumer electronics
- Firmware updates for networking gear (routers, gateways) and set-top boxes
- Infotainment and medical devices needing robust non-volatile storage
- Data logging and local firmware storage for IoT devices and smart meters
