The EN25QH64A-104FIP(2AC) is a 64 Mbit serial NOR Flash memory from ESMT, designed for high-performance code and data storage in embedded systems. It implements an SPI serial architecture with support for Standard, Dual and Quad SPI modes and a maximum clock rate of 104 MHz, enabling fast reads and flexible interface options.

With uniform 4-Kbyte sectors, industry-range operating temperatures and low-power modes, this device targets industrial embedded applications that require reliable non-volatile storage, block-level erase/program control and long data retention.

Key Features

• Memory Capacity & Organization — 64 Mbit (8,192 KByte) organized as 32,768 pages with 256 bytes per programmable page and 2048 uniform 4-Kbyte sectors for granular erase and program operations.
• Serial SPI Interface — SPI compatible with Mode 0 and Mode 3; supports Standard, Dual and Quad SPI (CLK, CS#, DI, DO and DQ₂/DQ₃ signals) with configurable dummy cycles.
• High-Speed Operation — 104 MHz clock rate for Standard, Dual and Quad operations, delivering equivalent Quad throughput up to 416 MHz (104 MHz × 4) when using Quad read instructions.
• Program and Erase Performance — Typical page program time 0.5 ms; sector erase ~40 ms; half-block erase ~200 ms; block erase ~300 ms; chip erase ~32 seconds. Page program supports 1–256 byte programming.
• Low Power — Typical active current around 5 mA and typical power-down current of 1 µA to support power-sensitive designs.
• Reliability & Data Retention — Minimum 100K program/erase cycles per sector or block and data retention specified at 20 years.
• Security & Protection — Software and hardware write protection options, write suspend/resume, lockable 3×512 byte OTP sector and unique ID read capability for system-level protection and identification.
• Package & Temperature — Available in a 16‑pin SOP 300 mil package; industrial temperature range specified from -40° C to +85° C. Device packages are RoHS compliant.

Typical Applications

• Embedded Firmware Storage — Store boot code, firmware images and patchable subroutines with sector-level protection to update specific modules without affecting the rest of memory.
• Industrial Control — Retain configuration, calibration data and application code in industrial environments requiring -40° C to +85° C operation.
• Consumer & IoT Devices — High-speed SPI and Quad read support for fast code execution and data access in connected devices and user interfaces.

Unique Advantages

• Flexible SPI Modes: Standard, Dual and Quad SPI support lets designers trade pin count for throughput and use the same device across different interface requirements.
• Granular Memory Management: Uniform 4-Kbyte sector architecture and multiple block sizes enable precise erase/program operations and simpler code update strategies.
• High Throughput at 104 MHz: Fast clocking for Standard, Dual and Quad operations reduces read latency and accelerates code fetch and data access.
• Low-Power Standby: Sub-microamp power-down current helps minimize energy draw in battery-assisted or power-constrained systems.
• Industrial Temperature Range: Specified -40° C to +85° C operation for use in demanding environments.
• Durability and Retention: 100K program/erase cycle endurance per sector or block and 20-year data retention support long-term field deployments.
