EN25SX128A-104FIP(2PC)

The EN25SX128A-104FIP(2PC) is a 128 Mbit serial SPI NOR Flash memory device in the EN25SX128A family from ESMT. It implements a serial SPI architecture with Standard, Dual and Quad I/O modes and is designed for code and data storage in industrial embedded systems.

With a fast 104 MHz read clock, uniform sector architecture and advanced write-protection mechanisms, this device targets firmware storage, field updates and embedded data segments where robust erase/program flexibility and long-term data retention are required.

Key Features

• Memory Capacity & Organization — 128 Mbit serial flash organized as 16M × 8 with 65,536 pages and 256 bytes per programmable page.
• SPI Interface & I/O Modes — Supports Standard, Dual and Quad SPI (Mode 0 and Mode 3) with standard SPI pins and Quad enable by default.
• High-Speed Read — 104 MHz clock rate for Single/Dual/Quad I/O Fast Read for responsive code and data access.
• Voltage and Power — Single power-supply operation with a documented full voltage range of 1.65–1.95 V; low active and deep power-down currents minimize system consumption.
• Program & Erase Performance — Typical page program time 0.5 ms; sector erase ~40 ms; half-block and block erase times documented for fast region-level updates.
• Endurance & Retention — Minimum 100K program/erase cycles per sector/block and greater than 20 years data retention.
• Flexible Memory Protection — Software and hardware write protection with block-level lock/unlock, lockable OTP security sector and write suspend/resume support.
• Uniform Sector Architecture — 4,096 × 4-Kbyte sectors, plus block granularity (32-Kbyte, 64-Kbyte) for selective erase operations.
• Package & Temperature — Available in 16-pin SOP 300 mil package; industrial operating range −40 °C to 85 °C.

Typical Applications

• Firmware & Boot Storage — Stores boot code and firmware images with support for in-field updates and page-level programming.
• Code Patching & Module Updates — Block- and sector-level protection enables selective updating of code modules while protecting other regions.
• Embedded Data Logging & Configuration — Non-volatile storage for configuration, calibration data or logged information with long retention and high endurance.

Unique Advantages

• Quad I/O Performance: Quad SPI support and 104 MHz read clock speed reduce read latency for code and data fetches.
• Granular Erase & Protection: Uniform 4-Kbyte sectors with block-level erase and software/hardware protection simplify secure updates and region management.
• Low Power Operation: Documented low active and power-down currents reduce system energy use in battery- or power-sensitive designs.
• High Endurance & Long Retention: Minimum 100K program/erase cycles and over 20 years data retention provide durability for long-life products.
• Industrial Temperature Range: −40 °C to 85 °C operation supports deployment in harsh or industrial environments.
• Design Flexibility: Standard, Dual and Quad SPI modes with default Quad Enable and SFDP support simplify integration across MCUs and controllers.
