EN25QH64A-104FIP(2A)

The EN25QH64A-104FIP(2A) from ESMT is a 64 Mbit serial NOR flash memory device with a Serial Peripheral Interface (SPI) architecture designed for reliable code and data storage. It delivers a combination of high-speed SPI operation, flexible I/O modes (Standard/Dual/Quad), and sector-level erase/program control tailored for embedded and industrial designs.

Built for systems requiring robust in-field update and protection mechanisms, the device supports high clock rates and low-power modes while operating across an industrial temperature range, enabling dependable non-volatile storage for firmware, configuration, and secure data.

Key Features

• Memory Capacity & Organization 64 M-bit serial flash organized as 8M × 8 with 8,192 KByte total capacity, 32,768 pages and 256 bytes per programmable page.
• Interface & Read Performance Serial SPI architecture supporting Standard, Dual and Quad SPI modes; up to 104 MHz clock for Standard, Dual and Quad reads with equivalent Quad throughput up to 416 MHz (104 MHz × 4) when using Quad Output Read instructions. Configurable dummy cycles and burst read with wrap (8/16/32/64 byte).
• Program / Erase Performance High performance program/erase timings: typical page program 0.5 ms, sector erase 40 ms, half-block erase 200 ms, block erase 300 ms, and full chip erase ~32 seconds (typical).
• Power Low power consumption with typical active current 5 mA and typical power-down current 1 μA. Single power supply operation over the device’s supported voltage range.
• Uniform Sector Architecture 2,048 uniform 4-Kbyte sectors, 256 blocks of 32-Kbyte and 128 blocks of 64-Kbyte enabling fine-grained erase and update control.
• Write Protection & Reset Software- and hardware-based write protection (WP# pin), write suspend/resume, and software/hardware reset support to protect code and critical data during updates.
• Security & Identification Lockable 3 × 512-byte OTP security sectors and Read Unique ID Number feature for device identification and secure storage zones.
• Reliability Minimum 100K program/erase cycles per sector and 20-year data retention specification for long-term storage stability.
• Package & Temperature Available in a 16-pin SOP 300 mil Pb‑free package with industrial operating temperature range –40 °C to 85 °C and RoHS compliance.

Typical Applications

• Industrial Control & Automation Non-volatile storage for firmware, configuration tables and field updates where industrial temperature range and sector-level erase are required.
• Embedded Firmware Storage Primary flash for boot code, firmware images and in-field code patches using sector/block erase and write-protect mechanisms.
• Secure ID & Configuration Storage of unique device identifiers and small secure configuration blocks using the lockable OTP sectors and Read Unique ID features.
• Systems Requiring In-Field Updates Devices that need reliable program/erase cycles and write suspend/resume support for safe firmware upgrades and rollback strategies.

Unique Advantages

• Flexible SPI I/O Modes: Support for Standard, Dual and Quad SPI modes at up to 104 MHz enables designers to balance pin usage and throughput for their application.
• Fine-Grained Erase Control: Uniform 4-Kbyte sectors and multiple block sizes let systems update small code modules without erasing larger memory regions, simplifying OTA and patch workflows.
• Fast Program and Erase: Typical page program at 0.5 ms and sector erase at 40 ms reduce update windows and speed system bring-up or field upgrades.
• Low-Power Operation: Typical active current of 5 mA and 1 μA power-down current help minimize energy impact in battery-assisted or energy-conscious systems.
• Robust Protection & Identification: Integrated software and hardware write protection, lockable OTP sectors and unique ID support secure storage of critical firmware and device identity.
• Industrial-Ready Packaging: Supplied in a 16-pin SOP 300 mil package with –40 °C to 85 °C operation and RoHS compliance for industrial deployment.
