EN35QXR512A-104YIP(2SC)

The EN35QXR512A-104YIP(2SC) is a 512 Megabit serial NOR Flash memory device from ESMT, engineered for industrial embedded applications. It implements a serial SPI architecture with Single, Dual and Quad I/O modes and is optimized for high-performance code and data storage in constrained, surface-mount form factors.

This industrial-grade device delivers fast read performance up to a 104 MHz clock rate (with additional Quad I/O options up to 133 MHz), uniform 4-Kbyte sector architecture and durable program/erase characteristics suitable for in-field updates and protected memory regions.

Key Features

• Memory Capacity & Organization — 512 Mbit serial Flash organized as 2M × 8 with 256‑byte programmable pages and 262,144 pages total for granular data and code storage.
• Interface & Read Performance — SPI-compatible serial interface supporting Standard, Dual and Quad SPI; Fast Read up to 104 MHz for Single/Dual/Quad I/O and Quad I/O support up to 133 MHz (series capability).
• Erase & Program Performance — Typical page program time of 0.5 ms; sector erase ~40 ms, half-block ~200 ms, block erase ~300 ms and full chip erase ~120 s, enabling fast updates and flexible memory management.
• Endurance & Data Retention — Minimum 100K program/erase cycles per sector and typical data retention of 20 years for long-term reliability in fielded systems.
• Power & Low‑Power Modes — Low active current (typical 24 mA) and power-down current (typical 2 µA) to help manage energy in battery-assisted or low-power systems.
• Security & Protection — Uniform 4-Kbyte sector architecture with software and hardware write protection, lockable OTP sector and Replay‑Protected Monotonic Counter (RPMC) for secure storage options.
• Package & Temperature — Surface-mount 8‑contact WSON package (8 × 6 mm) and industrial operating range of −40 °C to 85 °C for harsh-environment deployments.

Typical Applications

• Firmware and boot storage — Store boot code and firmware images with sector-level protection and support for in-field updates and code patching.
• Embedded system code shadowing — Use Quad SPI fast read modes to accelerate execute-in-place or code shadowing from serial Flash in microcontroller and MPU systems.
• Configuration and secure data storage — Leverage software/hardware write protection and lockable OTP for secure storage of configuration, calibration or device identity data.

Unique Advantages

• High-throughput serial read options — Up to 104 MHz (Single/Dual/Quad) with Quad I/O capability up to 133 MHz to reduce boot and data transfer times.
• Fine-grained memory control — 4-Kbyte uniform sector architecture and multiple block sizes allow selective erasure and updates without full-chip operations.
• Robust program/erase lifecycle — Designed for a minimum of 100K cycles per sector, supporting long-term updateable storage needs.
• Low-power standby — Typical 2 µA power-down current helps minimize standby energy consumption in always‑on or battery-assisted designs.
• Industrial-grade packaging — 8‑pin WSON 8×6 mm surface-mount package and −40 °C to 85 °C operating range for reliable installation in industrial environments.
• Flexible SPI modes — Standard, Dual and Quad SPI support provides compatibility with a wide range of host controllers and throughput requirements.
