EN25QH256A-104YIP(2RC)

The EN25QH256A-104YIP(2RC) from ESMT is a 256 Mbit serial SPI NOR Flash memory device designed for industrial embedded applications. It provides high-performance SPI read/write capability with support for Standard, Dual and Quad SPI modes and a 104 MHz clock rate for single-, dual- and quad-bit transfers.

Built with a uniform-sector architecture and both hardware and software write-protection features, this device is suited for firmware and code storage, in-field updates, and systems that require durable non-volatile storage across an industrial temperature range.

Key Features

• Memory Capacity & Organization — 256 Mbit total capacity organized as 32M × 8 with 256-byte programmable pages and 131,072 pages for flexible code and data layout.
• High-Speed SPI Interface — Supports Standard, Dual and Quad SPI with a 104 MHz clock rate for single, two-data-bit and four-data-bit transfers to accelerate code execution and data access.
• Uniform Sector Architecture — 8,192 × 4-Kbyte sectors (also 1,024 × 32-Kbyte and 512 × 64-Kbyte blocks) enabling individual sector or block erase operations and fine-grained update control.
• Program & Erase Performance — Typical page program time 0.5 ms; typical sector erase 40 ms, half-block 120 ms, block erase 150 ms and typical chip erase 100 seconds.
• Power & Low-Power Modes — Low active current (typical 6 mA) and low power-down current (typical 1 µA) for energy-conscious embedded systems.
• Write Protection — Software and hardware mechanisms including global or partial software protection and WP# pin support to enable/disable protection.
• Addressing & Standards — Supports 3-byte and 4-byte address modes and Serial Flash Discoverable Parameters (SFDP) signature for interoperability.
• Reliability — Minimum 100K program/erase cycles per sector and a typical data retention of 20 years.
• Package & Temperature — Available in an 8-contact WSON/VDFN 8 × 6 mm package and specified for industrial operation from −40 °C to 85 °C.

Typical Applications

• Industrial Control & Automation — Non-volatile code storage and field firmware updates for controllers and instrumentation operating across −40 °C to 85 °C.
• Embedded Systems & Microcontroller Storage — High-speed SPI boot and execute-in-place scenarios that benefit from 104 MHz read capability and quad SPI support.
• Connectivity & Edge Devices — Storage of firmware, configuration and calibration data with sector-level erase and robust write-protection options.

Unique Advantages

• Flexible SPI Modes: Standard, Dual and Quad SPI support with configurable dummy cycles enables designers to optimize throughput and latency for their interface needs.
• Fine-Grained Memory Management: Uniform 4-Kbyte sectors and multiple block sizes let systems perform targeted updates without erasing large memory regions.
• Robust Data Protection: Combined software and WP# hardware controls allow selective protection of code and data regions to reduce risk during updates.
• Low Power Operation: Typical active and power-down currents (6 mA active, 1 µA power-down) help minimize energy use in battery-backed or always-on systems.
• Long-Term Reliability: Rated for a minimum of 100K program/erase cycles per sector and ~20 years data retention for durable field operation.
• Industrial Temperature Range: Specified operation from −40 °C to 85 °C for deployment in temperature-challenging environments.
