Overview of EN35QX512A-133FIP(2SC) – 512 Mbit SPI NOR Flash, Industrial 16-pin SOP
The EN35QX512A-133FIP(2SC) is a 512 Mbit serial NOR flash memory device designed for industrial embedded systems requiring non-volatile code and data storage. It implements a serial SPI architecture with single, dual and quad I/O modes and delivers high-speed read performance with a Quad I/O Fast Read option at up to 133 MHz.
Engineered for reliability and in-field updates, the device provides uniform sector architecture, robust program/erase endurance, and hardware/software write protection features well suited for firmware, boot storage and other embedded memory uses across industrial temperature ranges.
Key Features
- Memory Capacity & Organization — 512 Mbit (64M × 8) serial NOR flash organized into 262,144 pages with 256 bytes per programmable page.
- High-Speed SPI Interface — SPI-compatible single/dual/quad I/O support. Quad I/O Fast Read up to 133 MHz (device supports 104 MHz for single/dual/quad fast read under typical conditions).
- Voltage and Power — Full operating voltage range noted in documentation at 2.7–3.6 V; low power consumption with typical active current ~14 mA and typical power-down current ~2 µA.
- Program / Erase Performance — Page program time ~0.5 ms typical; sector erase ~40 ms typical; half-block and block erase times and chip erase documented for system planning.
- Endurance & Retention — Minimum 100K program/erase cycles per sector/block and data retention time specified at 20 years.
- Uniform Sector Architecture & Protection — 4 KB uniform sectors (16,384 sectors), with software and hardware write-protect options, and lockable 3×512-byte OTP security sector for secure data.
- Advanced Functionality — Supports Serial Flash Discoverable Parameters (SFDP) signature and Read Unique ID Number for system identification and compatibility.
- Package & Temperature — Industrial-grade device available in a 16-pin SOP 300 mil package, surface-mount, with operating temperature range −40 °C to 85 °C.
Typical Applications
- Industrial Embedded Systems — Non-volatile storage for firmware, boot code and configuration data in controllers and automation equipment operating across industrial temperature ranges.
- Firmware Storage & Field Updates — Uniform sectors and program/erase endurance enable reliable in-field firmware updates and partial block programming.
- Boot and Code Storage — High-density serial flash for storing system bootloaders and application code with Quad SPI read performance for fast code fetch.
Unique Advantages
- High-capacity Serial Storage: 512 Mbit density provides ample space for large firmware images, code, and data while maintaining a compact package footprint.
- Flexible SPI I/O Modes: Single, Dual and Quad SPI support enables designers to trade off pin count and throughput to match system requirements.
- Fast Read Performance: Quad I/O Fast Read at up to 133 MHz reduces read latency for code execution and data access in performance-sensitive applications.
- Granular Erase & Protection: 4 KB uniform sectors with software and hardware write protection allow selective updates and secure memory regions without full-chip erases.
- Industrial-grade Reliability: Specified endurance and 20-year data retention, together with −40 °C to 85 °C operation, support long-term deployed systems.
- Compact Surface-Mount Package: 16-pin SOP 300 mil package simplifies PCB routing and assembly for space-constrained designs.
