Overview of EN35QXR256A-104YIP(2SC) – 256 Mbit SPI NOR Flash, 104 MHz, Industrial

The EN35QXR256A-104YIP(2SC) is a 256‑Mbit serial NOR Flash memory organized as 32M × 8 designed for industrial applications. It implements a SPI-compatible serial interface with Single, Dual and Quad I/O modes and supports high-speed Fast Read operations at a 104 MHz clock rate.

Engineered for code and data storage in embedded systems, this device delivers sector-level eraseability, fast page programming and low-power standby, making it suitable for firmware storage, boot code and non-volatile data logging in industrial environments.

Key Features

  • Memory Capacity & Organization — 256 Mbit device organized as 32M × 8 with 131,072 pages and 256 bytes per programmable page.
  • Serial SPI Architecture — Supports Standard, Dual and Quad SPI with single/dual/quad I/O options and SPI Mode 0 and Mode 3 compatibility.
  • High-Speed Read — 104 MHz clock rate for Single/Dual/Quad I/O Fast Read to support high-throughput boot and code-fetch scenarios.
  • Program & Erase Performance — Typical page program time 0.5 ms; typical sector erase time 40 ms, half-block and block erase options with typical times provided for each operation.
  • Low Power — Typical active current ~12 mA and typical power-down current ~1 μA for power-conscious embedded designs.
  • Uniform Sector Architecture — 8,192 sectors of 4-Kbyte for flexible sector-level erase and update; also provided as blocks of 32 KB and 64 KB.
  • Security & Reliability — Lockable 3 × 512 byte OTP security sector, replay‑protected monotonic counter (RPMC), minimum 100K program/erase cycles and 20‑year data retention.
  • Package & Temperature — Available in an 8‑contact WSON 8×6 mm package and specified for industrial temperature range (−40 °C to 85 °C).

Typical Applications

  • Embedded Firmware Storage — Reliable storage for boot code and firmware where fast read performance and sector-level updates are required.
  • Industrial Control — Non‑volatile program and parameter storage for PLCs, motor controllers and factory automation systems operating across −40 °C to 85 °C.
  • Factory Imaging & Field Upgrades — Supports block and sector erase operations and high endurance for repeated firmware updates and field flashing.
  • Secure Data Logging — OTP sector and RPMC support secure counters and small secure storage regions for tamper-resistant logging.

Unique Advantages

  • Flexible SPI Modes — Standard, Dual and Quad modes enable designers to scale throughput without changing the memory family.
  • Balanced Performance — 104 MHz fast read and 0.5 ms typical page program provide a practical balance between read throughput and programming efficiency.
  • Sector-Level Granularity — 4‑KB uniform sectors allow precise updates and reduce erase overhead for in-field firmware patches.
  • Industrial‑Grade Reliability — Specified operating temperature range and endurance/retention characteristics support long-term deployments in industrial equipment.
  • Low Standby Power — Sub‑microamp power-down current preserves battery and system standby energy budgets.
