EN25QX128A-104FIP(2X)

The EN25QX128A-104FIP(2X) from ESMT is a 128 Mbit serial SPI NOR Flash memory organized as 16M × 8. It implements a Serial Peripheral Interface with support for Standard, Dual and Quad I/O and delivers high performance reads at a 104 MHz clock rate for fast code and data access.

Designed for industrial applications, this non-volatile memory provides uniform 4 Kbyte sectors, flexible block/sector erase options, robust write protection and low-power standby behavior—making it suitable for firmware storage, field upgrades and long-term data retention in embedded systems.

Key Features

• Memory & Organization 128 Mbit capacity arranged as 16M × 8 with 256-byte programmable pages and 65,535 pages for fine-grained programming.
• Serial SPI Interface Supports Standard, Dual and Quad SPI modes (CLK, CS#, DQ0–DQ3) and SPI modes 0 and 3 for flexible system integration.
• High-Speed Read Fast read performance with a 104 MHz clock rate for Single/Dual/Quad I/O fast read operations to accelerate code fetch and data transfer.
• Uniform Sector Architecture 4,096 uniform 4-Kbyte sectors, 512 blocks of 32-Kbyte and 256 blocks of 64-Kbyte allow individual sector or block erase operations.
• Program & Erase Performance Typical page program time 0.5 ms; sector erase ~40 ms; half-block erase ~200 ms; block erase ~300 ms; chip erase ~60 s.
• Power & Reliability Low power consumption with ~6 mA typical active current and ~1 µA typical standby current; data retention time specified at 20 years and minimum 100K program/erase cycles per sector/block.
• Write Protection & Security Software and hardware write protection with WP# pin, volatile status register bits, and lockable 3 × 512-byte OTP security sectors.
• Industrial Temperature Range Specified for operation from −40 °C to 85 °C and available in Pb‑free, RoHS-compliant packages.
• Package Options Available in a 16-pin SOP 300 mil surface-mount package option (other series packages noted in datasheet).

Typical Applications

• Firmware Storage & Boot Non-volatile program storage for embedded controllers and boot code where fast read performance and sector-level erase are required.
• Field Upgrades & Code Patching Supports partial block protection and individual sector writes for reliable in-field firmware updates and patching of code modules.
• Configuration & Parameter Storage Secure storage of device configuration, calibration data or unique ID numbers with optional OTP security regions.
• Data Logging & Retention Low standby current and 20-year data retention make it suitable for long-term storage of logged data in industrial systems.

Unique Advantages

• Flexible I/O Modes: Standard, Dual and Quad SPI support enables designers to trade off pin count and throughput to match system needs.
• Fast System Boot and Reads: 104 MHz fast read capability reduces code fetch latency for quicker boot and application response.
• Granular Erase & Protection: Uniform 4-Kbyte sectors and software/hardware protection allow targeted updates while protecting critical regions.
• Robust Endurance & Retention: Specified ≥100K program/erase cycles and 20 years data retention ensure long-term reliability for deployed equipment.
• Low Power Standby: ~1 µA typical standby current helps minimize power consumption in battery-backed or always‑on systems.
• Industrial Temperature Rating: −40 °C to 85 °C operation supports deployment in a wide range of industrial environments.
