EN25QH64A-104FIP

The EN25QH64A-104FIP is a 64 Mbit serial NOR flash memory device in the ESMT SPI NOR EN25QH64A series, optimized for embedded storage and code execution in industrial applications. It uses a serial SPI architecture with support for Standard, Dual and Quad SPI modes to deliver high-speed reads and flexible I/O configurations.

Designed for robust system-level protection and long-term data retention, this industrial-grade device combines uniform sector architecture, hardware and software write-protection, and proven endurance characteristics to support firmware, parameter storage and boot code in industrial and embedded systems.

Key Features

• Memory & Organization  64 Mbit (8,192 K-byte) capacity organized as 8M × 8 with 256‑byte programmable pages and 4 Kbyte uniform sectors.
• High-performance Read  Standard, Dual and Quad SPI read modes with Standard/Dual/Quad fast read operation up to 104 MHz (configurable dummy cycles) for accelerated code and data fetch.
• Program / Erase Performance  Typical page program time 0.5 ms; sector erase typically 40 ms, half-block 200 ms, block 300 ms and chip erase ~30 seconds (typical values).
• Power and Supply  Single power supply operation with full voltage range specified in the family; low operating currents (typical active current ~5 mA) and ultra-low power-down current (~1 µA typical) to minimize system power consumption.
• Security & Protection  Software and hardware write protection, WP# pin, lockable 512‑byte OTP security sector, volatile status register bits and read-unique ID feature for secure identification.
• Reliability & Endurance  Designed for a minimum of 100K program/erase cycles per sector and typical data retention of 20 years.
• Package & Temperature  Available in a 16-pin SOP 300 mil package option with industrial temperature support (−40 °C to 85 °C) for harsh environments.

Typical Applications

• Embedded Firmware Storage  Non-volatile storage for boot code, firmware images and field updates where sector-level erase and high read throughput are required.
• Industrial Control  Storage of configuration, calibration and logging data in industrial controllers and automation equipment operating across an industrial temperature range.
• Networking & Communications  Firmware and parameter storage for network appliances and edge devices needing fast SPI reads and support for Dual/Quad I/O modes.
• Consumer & IoT Devices  External code/data storage for embedded consumer products and IoT modules that benefit from low-power standby and high-speed boot/read performance.

Unique Advantages

• Flexible SPI Interfaces  Standard, Dual and Quad SPI support enables designers to trade pin count versus throughput without changing the memory family.
• Uniform Sector Architecture  4 KB uniform sectors and multiple block sizes simplify firmware update strategies and enable targeted sector erase operations.
• Robust Protection Mechanisms  Combined software and hardware write-protect features plus a lockable OTP sector reduce the risk of accidental or unauthorized memory modification.
• Industrial Temperature Range  Specified −40 °C to 85 °C operation suits deployment in industrial and other temperature-demanding environments.
• Low Power Standby  Very low power-down current supports battery-backed and energy-efficient designs that need long idle periods.
• Proven Endurance and Retention  Minimum 100K program/erase cycles and long data retention provide predictable lifecycle behavior for deployed systems.
