EN25QH64A-104HIP(2AC)

The EN25QH64A-104HIP(2AC) is a 64 Mbit serial NOR Flash memory device in the ESMT EN25QH64A(2AC) series. It implements a SPI serial-interface architecture with support for Standard, Dual and Quad SPI modes and high-speed operation up to a 104 MHz clock.

Designed for industrial-grade embedded storage, the device provides uniform 4 KB sectors, flexible erase/program options and hardware/software protection mechanisms suited for code and data storage in industrial and embedded systems operating from −40°C to 85°C.

Key Features

• Memory & Organization 64 Mbit serial flash organized as 8M × 8 with 8,192 KByte total capacity, 32,768 pages and 256 bytes per programmable page.
• High-Speed SPI Interfaces Supports Standard, Dual and Quad SPI with configurable dummy cycles and up to 104 MHz clock rate (equivalent quad rates up to 416 MHz using Quad Output reads).
• Uniform Sector Architecture 4 KB uniform sectors (2,048 sectors), 256 blocks of 32 KB and 128 blocks of 64 KB; sectors or blocks can be erased individually.
• Program & Erase Performance Typical page program time 0.5 ms, sector erase time 40 ms, half-block erase 200 ms, block erase 300 ms and chip erase typical 32 seconds.
• Low Power Typical active current ~5 mA and typical power-down current ~1 μA to support low-power embedded designs.
• Protection & Reliability Software and hardware write protection (including WP#), software/hardware reset, write suspend/resume, minimum 100K program/erase cycles per sector and 20-year data retention.
• Security & Identification Lockable 3 × 512-byte OTP security sector and Read Unique ID Number for device identification.
• Package & Temperature Available in an 8-pin SOP 200 mil package; industrial temperature range of −40°C to 85°C. RoHS compliant.

Typical Applications

• Industrial Control Firmware and configuration storage where industrial temperature range and reliable erase/program cycles are required.
• Embedded Systems Code shadowing, boot storage and data logging for microcontroller-based systems using SPI interface at up to 104 MHz.
• Consumer & IoT Devices Non-volatile storage for firmware updates, configuration data and small file systems using Standard/Dual/Quad SPI.
• Networking & Communications Storage of boot images and configuration tables in devices that benefit from fast read throughput and Quad SPI support.

Unique Advantages

• Multi-Mode SPI Flexibility: Standard, Dual and Quad SPI support allows designers to scale throughput without changing the memory family.
• Uniform Sector Erase: 4 KB uniform sectors and block-level erase offer granular update capability for firmware patches or data segments.
• Fast Read Performance: 104 MHz clock rate enables high read throughput for fast boot and code execution from serial flash.
• Robust Data Retention and Endurance: 100K program/erase cycles and 20-year retention provide long-term reliability for deployed systems.
• Industrial-Grade Operation: −40°C to 85°C rating and SOP package options support rugged embedded deployments.
