EN25SX64A-104HIP(2UC)

The EN25SX64A-104HIP(2UC) is a 64 Mbit serial SPI NOR flash memory device designed for industrial embedded applications. Built on a serial interface architecture, it provides standard, dual and quad SPI modes with fast read performance and low power consumption.

Its combination of uniform 4 Kbyte sectors, fast program/erase characteristics and industrial temperature rating makes it suitable for code and data storage in systems that require durable non-volatile memory with flexible protection options.

Key Features

• Memory Capacity & Organization  64 Mbit (8,192 Kbyte) serial flash with 256-byte programmable pages and uniform 4-Kbyte sectors; supports sector, block and full-chip erase.
• Interface & Read Performance  SPI-compatible serial interface supporting Standard, Dual and Quad SPI. Fast read operation up to 104 MHz in Single/Dual/Quad I/O and up to 133 MHz for Quad I/O Fast Read.
• Program/Erase Performance  High-performance program and erase: typical page program time 0.5 ms, sector erase 40 ms, half-block and block erase times, and typical chip erase time of 30 seconds.
• Power & Voltage  Single power-supply operation with full voltage range of 1.65–1.95 V. Typical active current ~4.5 mA and power-down current ~0.1 μA for low-power operation.
• Reliability & Endurance  Minimum 100K program/erase endurance cycles per sector and data retention specified at 20 years.
• Protection & Security  Advanced software and hardware write protection, write suspend/resume, volatile status register bits and a lockable 3×512-byte OTP security sector.
• Packages & Temperature Range  Available in an 8‑lead SOP (200 mil) surface-mount package among other package options; industrial temperature range −40 °C to +85 °C.
• Standards & Compliance  Supports Serial Flash Discoverable Parameters (SFDP) and Read Unique ID Number commands. All Pb‑free packages are RoHS compliant.
• Performance Detail  8 ns access time and support for 1 to 256‑byte programming per Page Program instruction for flexible write granularity.

Typical Applications

• Industrial Control  Code and configuration storage for industrial controllers and automation equipment requiring an extended temperature range and robust erase/program endurance.
• Embedded Systems  Firmware and data storage for microcontroller-based designs that benefit from Serial/Quad SPI for fast code execution and in-field updates.
• Communications Equipment  Non-volatile storage of boot code, configuration tables and device identifiers where fast random access and protection mechanisms are required.

Unique Advantages

• Flexible SPI Modes: Standard, Dual and Quad SPI support gives designers options to trade off pin count vs. throughput without changing the memory family.
• Fast Read Throughput: Up to 104 MHz Fast Read (and 133 MHz on Quad I/O) enables quicker code fetch and data transfer for performance-sensitive applications.
• Granular Erase & Program: 4 Kbyte uniform sectors with page-level programming (up to 256 bytes) allow targeted updates and efficient flash management.
• Industrial Qualification: Rated for −40 °C to +85 °C and offered in surface-mount packages suitable for industrial environments.
• Low Power Operation: Typical active and power-down currents reduce system power consumption during both active and idle states.
• Robust Data Retention & Endurance: Minimum 100K program/erase cycles and 20 years of data retention provide long-term reliability for product lifecycles.
