EN35QX512A-104WIP(2S)

The EN35QX512A-104WIP(2S) from ESMT is a 512 Mbit serial SPI NOR flash memory device designed for industrial embedded storage. It implements a serial SPI architecture with Single/Dual/Quad I/O support and is optimized for code and data storage, firmware updates, and protected sector-level modifications.

With high-density 64M × 8 organization, uniform 4 KB sectors and fast read/program performance, this surface-mount 8‑pin WSON package delivers the capacity and reliability required for industrial applications across a wide operating range (–40 °C to 85 °C).

Key Features

• Memory Capacity & Organization — 512 Mbit serial flash with 64M × 8 organization, 65,536 KByte total and 256‑byte programmable pages for efficient block and page programming.
• Serial SPI Interface — Serial Interface Architecture compatible with Standard, Dual and Quad SPI modes (CLK, CS#, DI/DO, plus DQ₂/DQ₃ for extended I/O).
• High-speed Read — 104 MHz clock rate for Single/Dual/Quad I/O Fast Read; Quad I/O Fast Read up to 133 MHz (per device voltage range), enabling fast code execute-in-place and data access.
• Program & Erase Performance — Typical page program time ~0.5 ms, typical sector erase ~40 ms, half‑block and block erase options for flexible memory management.
• Write Protection & Security — Software and hardware write protection, WP# pin to enable/disable protection and lockable 3×512‑byte OTP security sector for small, permanent data storage.
• Endurance & Retention — Minimum 100K program/erase cycles per sector and 20 years data retention, supporting long-term field updates and reliability.
• Power & Low‑Power Modes — Single power supply operation across the full device range; low active and power‑down currents for efficient system power management.
• Industrial Temperature & Package — Industrial grade (–40 °C to 85 °C) in an 8‑pin WSON surface-mount package (5 × 6 mm) suitable for compact board designs.
• Standards & Discoverability — Supports Serial Flash Discoverable Parameters (SFDP) and Read Unique ID for device identification and compatibility in SPI ecosystems.
• RoHS Compliant — Pb‑free packages compliant with RoHS and environmental requirements.

Typical Applications

• Embedded Firmware Storage — Reliable non‑volatile storage for system boot code and firmware images, with sector-level protection for safe in-field updates.
• Field Upgrade & Patching — Supports partial block protection and page programming for targeted code patches and incremental firmware upgrades.
• Industrial Control & Instrumentation — Industrial temperature range and robust endurance make it suitable for controllers, PLCs and instrumentation that require long-term code retention.
• System Configuration & Secure Data — Lockable OTP sector and unique ID features provide a small secure area for device configuration or calibration data.

Unique Advantages

• High-density, compact solution: 512 Mbit capacity in an 8‑pin WSON reduces board space while offering large storage for code and data.
• Flexible SPI I/O modes: Standard, Dual and Quad SPI support enables designers to balance pin usage and throughput according to system needs.
• Sector-level management: Uniform 4 KB sectors and multiple block/sector erase options let you update or protect only the regions you need, minimizing erase/program cycles on other data.
• Fast program and read performance: Low page program time (~0.5 ms) and high-frequency Fast Read modes accelerate firmware updates and system boot times.
• Robust field reliability: Minimum 100K P/E cycles and 20‑year data retention support long-life deployments and repeated update cycles in the field.
• Hardware and software protection: WP# pin plus software protection bits provide layered write protection for critical code and data.
