EN25QY256A-104FIP(2UC)

The EN25QY256A-104FIP(2UC) is a 256 M-bit serial SPI NOR flash memory from ESMT designed for industrial embedded storage and code retention. It provides a serial interface with Single/Dual/Quad I/O support, high-speed Fast Read up to 104 MHz, and uniform 4-Kbyte sectors for flexible erase and program operations.

Targeted at applications requiring reliable non‑volatile storage, the device combines field update capability, software and hardware write protection, and low-power standby modes to support robust firmware and data storage in industrial environments.

Key Features

• Memory & Organization 256 M-bit capacity (32,768 KByte) with 131,072 pages and 256 bytes per programmable page; uniform sector architecture with 4-Kbyte sectors, 32-Kbyte and 64-Kbyte block options.
• Interface & Performance Serial SPI architecture compatible with Standard, Dual and Quad SPI modes (SPI Mode 0 and Mode 3). Fast Read supported up to a 104 MHz clock rate with configurable dummy cycles and support for 3-byte/4-byte address modes.
• Program & Erase Speed High-performance program and erase timings: typical page program time 0.5 ms and typical sector erase time 40 ms; chip erase typical 120 seconds.
• Power Single power supply operation with full voltage range 2.7–3.6 V. Low power consumption with typical active current ~7 mA and typical power-down current ~1 µA.
• Reliability & Endurance Minimum 100K program/erase cycles per sector or block and more than 20 years data retention; industrial temperature range -40 °C to 85 °C.
• Security & Protection Software and hardware write protection, lockable 3×512 byte OTP security sector, Read Unique ID, and support for Serial Flash Discoverable Parameters (SFDP).
• Package & Mounting Available in a 16-pin SOP 300 mil package with surface-mount mounting; all Pb-free packages are RoHS compliant.

Typical Applications

• Firmware and Boot Storage Reliable program and erase capability with block protection and uniform sectors for in-field firmware updates and boot code storage.
• Industrial Control & Instrumentation Industrial temperature rating (-40 °C to 85 °C) and low-power modes make the device suitable for embedded controllers, PLCs, and instrumentation requiring non-volatile program memory.
• Networking & Communications High read clock (104 MHz) and Quad I/O support enable fast code and configuration fetch for network appliances and edge devices.
• Data Logging & Configuration Storage Uniform 4-Kbyte sectors and software/hardware protection let systems store and selectively update configuration and application data securely.

Unique Advantages

• Flexible Serial I/O Modes: Supports Standard, Dual and Quad SPI for scalable throughput depending on system needs and pin availability.
• Field-Upgradeable Memory: Uniform sectors and software/hardware protection enable safe in-field patching and selective block updates without exposing the entire memory.
• Low-Power Operation: Typical active current around 7 mA with deep power-down current near 1 µA reduces standby power draw in battery-assisted or energy-conscious systems.
• Industrial-Grade Reliability: Specified -40 °C to 85 °C operation and a minimum 100K program/erase cycle endurance support long-term deployments in demanding environments.
• Convenient Package Options: 16-pin SOP 300 mil surface-mount package simplifies PCB layout and assembly for compact embedded designs.
