The EN35QX512A-133WIP(2SC) is a 512 Mbit serial NOR flash memory device offering high-density non-volatile storage in a compact surface-mount package. It implements a serial SPI architecture with support for single, dual and quad I/O, delivering fast read throughput and flexible program/erase control for embedded and industrial designs.

Designed for applications that require reliable firmware and data storage, the device provides uniform 4-Kbyte sectors, hardware and software write protection, and an industrial operating temperature range of -40°C to 85°C.

Key Features

• Memory Capacity & Organization — 512 Mbit (65,536 KByte) total capacity organized as 64M × 8 with 256-byte programmable pages and 262,144 pages for efficient block/page-level updates.
• Serial SPI Interface — Supports Standard, Dual and Quad SPI modes with standard pins (CLK, CS#, DI, DO) and DQ₂/DQ₃ for Dual/Quad. Default Quad Enable (QE) = 1 and WP#/HOLD# are disabled by default.
• High-Speed Read — Fast read support up to 104 MHz for Single/Dual I/O and up to 133 MHz for Quad I/O Fast Read modes.
• Program & Erase Performance — Typical page program time ~0.5 ms; typical erase times include 40 ms for a 4-Kbyte sector, 200 ms half-block, 300 ms block, and ~120 s chip erase.
• Uniform Sector Architecture — 16,384 × 4-Kbyte sectors with additional block granularities (2,048 × 32-Kbyte and 1,024 × 64-Kbyte) for flexible erase and update strategies.
• Reliability — Minimum 100K program/erase cycles per sector and 20 years data retention for robust field lifetime expectations.
• Power — Low power profile with typical active current ~14 mA and typical power-down current ~2 μA.
• Security & Identification — Lockable 3 × 512-byte One-Time-Programmable (OTP) sector and unique ID read capability; supports Serial Flash Discoverable Parameters (SFDP).
• Voltage & Temperature Range — Single-supply operation with full voltage range 2.7–3.6 V and industrial operating temperature range −40°C to 85°C.
• Package — Available in an 8-contact WSON/VDFN (6 × 5 mm) surface-mount package; standard surface-mount mounting for compact board designs.

Typical Applications

• Firmware and Boot Code Storage — Store system firmware and bootloaders with support for in-field updates and subroutine-level patching.
• Embedded & Industrial Systems — Industrial temperature rating and robust endurance make it suitable for embedded controllers and industrial instruments.
• Modular Code Updates — Uniform-sector architecture and per-sector protection enable selective updates to code/data without erasing unrelated regions.

Unique Advantages

• Flexible I/O Modes: Single/Dual/Quad SPI support lets designers trade off pin count and throughput to match system requirements.
• Granular Erase & Protection: 4-Kbyte uniform sectors plus block options and software/hardware write protection simplify firmware management and secure regions of memory.
• High Read Performance: Quad I/O Fast Read at up to 133 MHz accelerates code execution and data transfer for time-sensitive applications.
• Field-Proof Endurance: 100K program/erase cycle minimum and 20-year retention provide predictable lifetime characteristics for long-life products.
• Low Power Standby: Very low power-down current reduces standby energy consumption in battery-assisted or always-on systems.
• Industry-Grade Operating Range: −40°C to 85°C rating supports deployment in industrial and demanding environments.
