EN25S64A-104HIP

The EN25S64A-104HIP is a 64 M-bit SPI NOR non-volatile flash memory in the EN25S64A family, delivered in an industrial temperature grade. Built on a serial SPI architecture, it supports Standard, Dual and Quad SPI modes and is optimized for high-speed code and data storage in embedded systems that require block-level erase and robust write protection.

Key value propositions include high read throughput (up to 104 MHz fast read), flexible sector/block erase granularity, and hardware/software protection features that simplify firmware update and secure storage use cases in industrial applications.

Key Features

• Memory Capacity & Organization 67.11 Mbit organized as 512K × 8 with 256-byte programmable pages and 32,768 pages total as documented for the EN25S64A family.
• High-speed Read Performance Fast read operation up to 104 MHz (Standard/Dual SPI) with configurable dummy cycles; normal read supported at 83 MHz. Typical access time is 7.5 ns.
• Program & Erase Performance Typical page program time 0.5 ms (datasheet typical); sector erase, half-block and block erase times listed as 40 ms, 200 ms and 300 ms typical respectively; chip erase time typical 32 seconds. Product specification lists write cycle time (word/page) at 3 ms.
• Interface Options Serial SPI compatible interface supporting Mode 0 and Mode 3, with Standard, Dual and Quad SPI command sets and dedicated control pins (CLK, CS#, DI/DO, WP#, HOLD#/RESET#).
• Protection & Security Uniform sector architecture with 4 KB sectors, support for software and hardware write protection, WP# pin control, software/hardware reset, and a lockable 512-byte OTP security sector.
• Endurance & Retention Minimum 100K program/erase cycles per sector or block and typical data retention time of 20 years.
• Power & Low Power Modes Low active and standby currents reported for the series (typical active current ~3.5 mA, typical power-down current ~1 μA) to help minimize system power draw.
• Package & Temperature Available in an 8-pin SOP 200mil surface-mount package; industrial operating temperature range of −40 °C to 85 °C. RoHS compliant.

Typical Applications

• Firmware and Boot Storage Block-erasable sectors and page-program capability make the device suitable for storing boot code, firmware images and in-field updates.
• Industrial Control Systems Industrial temperature rating and non-volatile storage characteristics support control firmware, configuration and logging in factory and process automation equipment.
• Networking & Communications Equipment High-speed SPI read modes and quad I/O options enable fast fetch of code and configuration data in routers, switches and edge devices.
• Embedded Appliances & Consumer Devices Compact 8-pin packaging and low power standby behavior suit compact embedded controllers and user-interface modules that require persistent storage.

Unique Advantages

• Flexible SPI Modes: Standard, Dual and Quad SPI support lets system designers balance performance and pin count according to application needs.
• Fine-Grained Erase Control: 4 KB uniform sectors and larger block erase options allow targeted updates and reduce wear on unaffected code/data regions.
• Built-in Protection Mechanisms: Software and hardware write protection, plus a lockable OTP sector, provide layered protection for critical code and data.
• Industrial Reliability: Rated for −40 °C to 85 °C and a minimum of 100K erase/program cycles, the device is suited to long-life embedded applications.
• Compact, Surface-Mount Packaging: An 8-pin SOP 200mil package enables small-footprint board designs while maintaining access to dedicated control pins.
