EN25QY256A-133FIP(2SC)

The EN25QY256A-133FIP(2SC) is a 256 Mbit serial SPI NOR Flash memory optimized for industrial-grade embedded storage. It implements a serial interface architecture supporting Standard, Dual and Quad SPI modes and is designed for code storage, in-field updates and data retention in industrial systems.

Built for high-performance read and program operations, the device provides configurable I/O modes, uniform 4 Kbyte sectors and industry-focused reliability features such as 100k program/erase endurance and 20-year data retention.

Key Features

• Memory Capacity & Organization  256 Mbit total capacity organized as 32M × 8 with 131,072 pages and 256 bytes per programmable page.
• Serial SPI Interface  Supports Standard, Dual and Quad SPI with SPI-compatible Mode 0 and Mode 3 signaling; Default QE=1 enables Quad I/O operation.
• High-Speed Read  Quad I/O Fast Read support up to 133 MHz (104 MHz for Single/Dual/Quad I/O Fast Read in lower modes), with configurable dummy cycle number.
• Program & Erase Performance  Typical page program time 0.5 ms; typical sector erase 40 ms, half-block 200 ms, block erase 300 ms, and chip erase 120 s.
• Robust Data Integrity  Minimum 100k program/erase cycles per sector/block and 20 years data retention ensure long-term storage reliability.
• Uniform Sector Architecture  8,192 uniform 4-Kbyte sectors plus 1,024 32-Kbyte blocks and 512 64-Kbyte blocks for flexible erase granularity.
• Protection & Security  Software and hardware write protection, lockable 3 × 512-byte OTP security sector and read-unique ID number.
• Power & Operating Range  Single-supply operation across 2.7–3.6 V with low typical active current (~7 mA) and ~1 µA power-down current.
• Package & Temperature  Available in 16-pin SOP 300 mil surface-mount package; industrial temperature range (-40 °C to 85 °C) and RoHS compliant.

Typical Applications

• Industrial Control & Automation  Non-volatile code and configuration storage for controllers and PLCs where industrial temperature range and endurance are required.
• Embedded Firmware Storage  Primary or secondary firmware/boot storage supporting in-field updates, partial sector protection and code patching.
• IoT & Edge Devices  Reliable program and data retention for edge nodes that require compact, low-power non-volatile memory with fast read performance.

Unique Advantages

• Flexible I/O Modes: Standard, Dual and Quad SPI support (with default Quad Enable) gives designers options to balance pin count and throughput.
• Granular Erase Architecture: Uniform 4 KB sectors and multiple block sizes allow selective erasure and efficient firmware updates without full-chip erase.
• Industrial Reliability: 100k program/erase cycle endurance and 20-year data retention provide robust long-term storage for critical applications.
• Fast Read Performance: Up to 133 MHz Quad I/O Fast Read capability accelerates code fetch and boot times in performance-sensitive designs.
• Low Power Standby: Typical 1 µA power-down current helps minimize energy use in battery-assisted or low-power systems.
• Compact, Surface-Mount Package: 16-pin SOP 300 mil SMD package enables straightforward placement on high-density PCBs for industrial assemblies.
