The EN35QXR512A-133FIP(2SC) is a 512 Mbit serial flash memory device in the ESMT EN35QXR512A series. It implements a SPI serial-interface architecture with Single, Dual and Quad I/O support and is offered in a 16‑pin SOP 300mil package for surface-mount applications.

Designed for firmware and code storage, field updates and data logging in industrial environments, the device delivers fast Quad I/O read performance (133 MHz Quad I/O Fast Read) and supports uniform 4‑Kbyte sectors, flexible erase granularity and software/hardware write protection.

Key Features

• Memory Capacity & Organization — 512 M‑bit (65,536 KByte) memory organized as 262,144 pages with 256 bytes per programmable page and uniform 4‑Kbyte sectors.
• SPI Interface Modes — Standard, Dual and Quad SPI support with standard SPI signals (CLK, CS#, DI, DO) and extended Quad signals (DQ0–DQ3). Default QE (Quad Enable) = 1 and configurable dummy cycles.
• High-Speed Read — Quad I/O Fast Read up to 133 MHz; also supports Fast Read up to 104 MHz for single/dual/quad I/O modes.
• Program & Erase Performance — Typical page program time 0.5 ms; sector erase typical 40 ms; half block and block erase timings provided for flexible memory management.
• Reliability & Data Retention — Minimum 100K program/erase cycles per sector/block and typical data retention of 20 years.
• Security & System Features — Lockable 3×512‑byte OTP security sector, Read Unique ID, Replay‑Protected Monotonic Counter (RPMC), and support for Serial Flash Discoverable Parameters (SFDP).
• Power & Low-Power Modes — Low active current (typical 24 mA) and low power-down current (typical 2 µA) for energy-conscious designs.
• Voltage & Supply Options — Series supports single-supply operation and a full voltage range described in the product documentation; exact supply variant is defined by ordering option.
• Package & Temperature Range — Surface-mount 16‑pin SOP 300mil package; industrial operating temperature range −40 °C to 85 °C.
• Addressing & Capacity Scaling — Supports both 3‑byte and 4‑byte addressing modes to access full memory space.

Typical Applications

• Industrial Control — Store firmware and configuration data with sector-level erase and protect features suitable for industrial controllers and PLCs operating across −40 °C to 85 °C.
• Embedded Systems — Host code and boot images for microcontrollers and FPGAs where Quad I/O fast read and page program flexibility accelerate boot and update processes.
• Networking & Communications — Non-volatile storage for configuration, authentication IDs and firmware images in networking modules and edge devices.
• Consumer & IoT Devices — Reliable code and data storage for field updates, secure ID and monotonic counters in connected products.

Unique Advantages

• Large, Uniform Memory Layout: 4‑Kbyte uniform sectors and page‑program granularity simplify partitioning for code, data and secure storage regions.
• Flexible SPI Modes: Standard, Dual and Quad I/O options enable designers to trade bandwidth and pin usage according to system needs.
• Fast Quad Read Performance: 133 MHz Quad I/O Fast Read reduces code fetch time and improves system boot and update responsiveness.
• Field Update and Protection: Software and hardware write protection combined with lockable OTP and RPMC support secure in‑field updates and sensitive data storage.
• Industrial Temperature Rating: Qualified for −40 °C to 85 °C operation for robust deployment in demanding environments.
• Proven Endurance and Retention: 100K program/erase cycle endurance and 20‑year data retention provide long-term reliability for product lifecycles.
