EN25QX256A-104FIP(2SC)

The EN25QX256A-104FIP(2SC) is a 256 Megabit serial NOR flash memory device based on SPI NOR architecture. It delivers single/dual/quad SPI operation and high-speed Fast Read performance, targeting industrial embedded storage and code/data shadowing applications that require non-volatile, field-updatable memory.

Designed for industrial temperature operation, the device combines uniform-sector erase architecture, hardware and software write protection, and fast program/erase timing to support firmware storage, boot code, and data logging in space-constrained surface-mount designs.

Key Features

• Memory Capacity and Organization 256 M-bit density organized as 32M × 8 with 256-byte programmable pages and 131,072 pages total.
• Serial SPI Interface SPI-compatible serial interface with Standard, Dual and Quad I/O support (CLK, CS#, DI/DO, DQ₂, DQ₃). Supports SPI Mode 0 and Mode 3.
• High-Speed Read Fast Read operation up to 104 MHz for Single/Dual/Quad I/O; Quad I/O Fast Read can operate at 133 MHz when supplied within 3.0–3.6 V range.
• Program/Erase Performance Typical page program time 0.5 ms; sector erase typical 40 ms; half-block and block erase typical 200 ms and 300 ms respectively; full chip erase typical 120 s.
• Uniform Sector Architecture 4 KByte uniform sectors with 8,192 sectors, plus 1,024 32-KByte blocks and 512 64-KByte blocks for flexible erase granularity.
• Power Single power-supply operation with low-power behavior: typical active current ~7 mA and typical power-down current ~1 μA.
• Reliability and Security Minimum 100K program/erase cycles per sector and 20 years data retention. Includes lockable 3 × 512-byte OTP security sector and support for Serial Flash Discoverable Parameters (SFDP) and Unique ID read.
• Package and Mounting Surface-mount package in 16-pin SOP 300 mil body width, suitable for compact PCB layouts.
• Industrial Temperature Range Specified operation from −40 °C to +85 °C for industrial applications.

Typical Applications

• Embedded Firmware Storage Store boot code and firmware images with uniform-sector erase and in-field update capability.
• Microcontroller Shadowing / Execute-in-Place High-speed SPI Fast Read and Quad I/O options enable faster code retrieval for performance-sensitive systems.
• Data Logging and Configuration Non-volatile storage for configuration parameters, logs, and calibration data with long retention and write-protect features.
• Industrial Control and Instrumentation Robust temperature range and surface-mount packaging make it suitable for industrial controllers and embedded instrumentation.

Unique Advantages

• Flexible SPI Modes: Standard, Dual and Quad I/O provide designers options to scale throughput without changing the memory family.
• Fine-Grained Erase Control: 4 KByte uniform sectors and larger block sizes allow precise updates and efficient use of erase cycles.
• Fast Program and Erase: Short typical program and sector-erase times reduce firmware update windows and improve production programming throughput.
• Low-Power Standby: Typical 1 μA power-down current helps conserve energy in battery-assisted or low-power systems.
• Industrial-Rated Operation: −40 °C to +85 °C range supports deployment in demanding ambient conditions.
• Security and Identification: Lockable OTP sector and Read Unique ID support system-level protection and device tracking.
