EN25QX256A-104HIP(2SC)

The EN25QX256A-104HIP(2SC) from ESMT is a 256 M-bit serial NOR flash memory device offering high-density non-volatile storage in SPI-compatible architectures. Designed around a serial SPI NOR core, it supports Standard, Dual and Quad SPI modes and provides uniform 4-Kbyte sectors for flexible program/erase control.

This industrial-grade device is optimized for applications that require high-capacity code and data storage with sector-level erase and robust write-protection mechanisms. Key value comes from fast read performance, multiple I/O modes, and long-term data retention suitable for demanding embedded and industrial environments.

Key Features

• Memory Capacity & Organization  256 M-bit (32,768 KByte) organized as 32M × 8 with 131,072 pages and 256 bytes per programmable page.
• Serial SPI Interface  Supports Standard, Dual and Quad SPI with SPI-compatible Mode 0 and Mode 3 signaling; standard pins include CLK, CS#, DI, DO and extended DQ₂/DQ₃ for Quad I/O.
• High-Speed Read Performance  Fast Read up to 104 MHz for Single/Dual/Quad I/O and up to 133 MHz for Quad I/O (3.0–3.6 V operation), with configurable dummy cycle number.
• Program & Erase Performance  Typical page program time 0.5 ms; sector erase typically 40 ms; half-block and block erase options and typical chip erase time 120 s enable flexible memory maintenance.
• Uniform Sector Architecture  8,192 uniform 4-Kbyte sectors, plus 1,024 × 32-Kbyte and 512 × 64-Kbyte block arrangements for fine-grained or large-area erase operations.
• Write Protection & Security  Hardware and software write-protect features, lockable 3×512-byte OTP security sector, and volatile status register bits to control protection.
• Reliability & Data Retention  Minimum 100K program/erase cycles per sector/block and typical data retention of 20 years.
• Low Power Operation  Typical active current ~7 mA and typical power-down current ~1 µA for energy-conscious designs.
• Industrial Temperature & Package  Industrial operating range −40 °C to 85 °C and available in compact surface-mount packages including 8-pin SOP (200 mil) body width.

Typical Applications

• Firmware Storage & In-field Updates  Sector-level erase and software/hardware protection enable safe patching and field updates of program code without affecting protected regions.
• Boot and System Code  High-density serial flash for storing bootloaders and system firmware that require reliable non-volatile retention and read performance.
• Configuration & Data Logging  Dedicated OTP and lockable sectors along with long data retention make the device suitable for secure configuration and persistent data storage.

Unique Advantages

• Large, Byte-Programmable Capacity: 256 M-bit density with 256-byte programmable pages supports sizable code and data storage in a compact footprint.
• Flexible I/O Modes: Standard, Dual and Quad SPI support accelerates read throughput and enables designers to optimize performance vs. pin count.
• Granular Erase Controls: Uniform 4-Kbyte sectors and multiple block sizes allow targeted erase operations to reduce wear and speed updates.
• Robust Protection Features: Combined hardware and software protection, volatile status bits, and an OTP security sector enhance data and code integrity.
• Industrial Reliability: Rated for −40 °C to 85 °C operation with 100K program/erase cycles and 20-year data retention for long-term deployments.
• Low Power Profile: Typical active and power-down currents support battery-backed and low-power embedded systems.
