EN35QX512A-104FIP(2S)

The EN35QX512A-104FIP(2S) is a 512 M-bit serial NOR Flash memory device built on SPI serial architecture. It offers high-density, non-volatile storage organized as 64M × 8 with 256-byte programmable pages and uniform 4-Kbyte sectors, suitable for embedded and industrial systems that require in-system programmability and reliable code/data retention.

With single/dual/quad SPI I/O, fast read clock support and hardware/software write-protect features, this device targets applications needing flexible update strategies, block-level protection and long-term data retention across an industrial temperature range.

Key Features

• Memory Capacity & Organization — 512 M-bit capacity (64M × 8) providing 65,536 KByte of serial Flash with 256-byte programmable pages and 262,144 programmable pages in total.
• Serial SPI Interface & Modes — SPI-compatible single, dual and quad I/O support with standard pins (CLK, CS#, DI, DO, WP#, HOLD#) and multi-bit I/O (DQ0–DQ3) for flexible system integration.
• High-Speed Read — Fast Read operation up to 104 MHz for Single/Dual/Quad I/O, enabling efficient code and data fetch in performance-sensitive designs.
• Program/Erase Performance — Typical page program time 0.5 ms; sector erase ~40 ms; block and chip erase times provided for rapid field updates and manufacturing programming.
• Power & Reliability — Low-power operation with typical active current ~14 mA and typical suspend/power-down current ~2 μA; supports a full operating voltage range of 2.7–3.6 V.
• Sector Architecture & Flexibility — Uniform 4-Kbyte sectors (16,384 sectors) plus 32-Kbyte and 64-Kbyte block organization, allowing individual sector or block erase operations.
• Protection & Security — Software and hardware write protection with WP# pin, volatile status register bits, and a lockable 3 × 512-byte OTP security sector for secure storage of critical data.
• Endurance & Data Retention — Minimum 100K program/erase cycles per sector and data retention specified at 20 years.
• Package & Temperature — Supplied in a 16-pin SOP 300 mil package and rated for industrial temperature range (−40 °C to 85 °C).
• Standards & Features — Supports SFDP (Serial Flash Discoverable Parameters), Read Unique ID, and both 3-byte and 4-byte addressing modes for large-memory addressing.

Typical Applications

• Embedded Firmware Storage — Store and execute firmware with in-system programmability and fast read performance for boot code and application code storage.
• Field Updates & Code Patching — Enable module-level updates or patches by unprotecting specific sectors or blocks while keeping other regions protected.
• Industrial Control Systems — Non-volatile configuration and code storage across −40 °C to 85 °C; suitable for industrial equipment requiring reliable retention and endurance.
• Secure Data & Configuration Storage — Protect critical calibration data or device-specific IDs using the lockable OTP sector and hardware write-protect features.

Unique Advantages

• Large, Uniform Sector Layout: 4-Kbyte uniform sectors allow fine-grained erase and update operations without requiring large block erases.
• Multi-Mode SPI Flexibility: Standard, Dual and Quad SPI support lets designers balance pin count and throughput to match system requirements.
• Fast Read Throughput: 104 MHz Fast Read capability for Single/Dual/Quad I/O accelerates code fetch and data transfer in embedded systems.
• Robust Program/Erase Characteristics: Typical page program time of 0.5 ms and defined sector/block/chip erase times support efficient manufacturing and field reprogramming.
• Low-Power Standby and Active Operation: Typical 14 mA active current and ~2 μA power-down current reduce system power draw during active and standby modes.
• Durability and Longevity: Specified minimum 100K program/erase cycles per sector and 20-year data retention support long-term deployment needs.
