EN25QY256A-104HIP(2UC)

The EN25QY256A-104HIP(2UC) is a 256 M-bit SPI NOR serial flash memory designed for industrial-grade embedded storage. It provides a serial SPI architecture with Single, Dual and Quad I/O support and high-speed read capability at a 104 MHz clock rate.

Targeted for systems that require reliable non-volatile code and data storage, this device delivers uniform 4 Kbyte sectors, flexible block/sector erase, and hardware/software protection features to support firmware updates and controlled data modification in industrial environments.

Key Features

• Memory Capacity & Organization — 256 M-bit capacity organized as 32,768 KByte total with 131,072 pages and 256 bytes per programmable page; uniform 4 Kbyte sectors (8,192 sectors) for predictable erase/program control.
• High-Speed SPI Interface — Supports Standard, Dual and Quad SPI modes with Single/Dual/Quad I/O Fast Read up to 104 MHz clock rate for fast code and data access.
• Voltage & Power — Single-supply serial flash operating across a full 2.7–3.6 V range; low power with typical active current ~7 mA and typical power-down current ~1 µA.
• Program & Erase Performance — Page program time typically 0.5 ms; sector erase typically 40 ms, half block erase typically 200 ms, block erase typically 300 ms, and chip erase typically 120 s for a full-chip operation.
• Reliability & Endurance — Minimum 100K program/erase cycles per sector and greater than 20-year data retention for long-term field reliability.
• Security & Identification — Lockable 3×512-byte OTP security sector and Read Unique ID support; supports Serial Flash Discoverable Parameters (SFDP) for interoperability.
• Flexible Addressing & Protection — 3-byte/4-byte address mode support and software/hardware write protection to protect code and data segments selectively.
• Package & Temperature — Available in 8-pin SOP 200 mil package and other package options; industrial temperature range from −40 °C to 85 °C.

Typical Applications

• Firmware storage and in-field updates — Maintain and update program code on a subroutine or module basis using sector/block protection and uniform sector architecture.
• Embedded systems and controllers — Store boot code, configuration data, and firmware in industrial embedded designs operating across −40 °C to 85 °C.
• Data and configuration retention — Preserve device parameters, calibration data, and logs with long data-retention characteristics and high endurance.

Unique Advantages

• Quad I/O performance: Native Quad SPI support and default Quad Enable (QE=1) enable higher throughput for fast code fetch and large-data reads.
• Predictable erase granularity: 4 Kbyte uniform sectors and multiple block sizes (32 Kbyte, 64 Kbyte) allow precise erase operations and efficient use of flash space.
• Low-power operation: Typical active and power-down currents help reduce system power consumption during active transfers and deep-sleep modes.
• Field-update readiness: Software and hardware write-protect features plus lockable OTP support simplify secure firmware update and protected data storage workflows.
• Industrial robustness: Industrial temperature rating and proven endurance (≥100K cycles) make the device suitable for long-life deployments in demanding environments.
