EN35QX512A-133HIP(2SC)

The EN35QX512A-133HIP(2SC) is a 512 Mbit serial SPI NOR Flash device optimized for high-speed Quad I/O read operations in industrial-temperature applications. Built on a serial interface architecture with single-supply operation and advanced protection features, it is suited for embedded code and data storage where fast read performance, flexible erase granularity and robust endurance are required.

Key Features

• Memory Core 512 M-bit organized as 64M × 8 with 256-byte programmable pages and 4-Kbyte uniform sectors for predictable block management.
• High-speed Read Modes Supports Standard, Dual and Quad SPI. Fast Read performance up to 104 MHz for single/dual/quad I/O and up to 133 MHz for Quad I/O fast read.
• Program / Erase Performance Typical page program time 0.5 ms (500 µs). Typical erase times: 4 KB sector ~40 ms, half-block ~200 ms, block ~300 ms, chip erase ~120 s.
• Power and Supply Single power supply operation with full voltage range specified in the datasheet; low active and standby currents with typical active current ~14 mA and power-down current ~2 μA.
• Interface and Addressing SPI-compatible commands (Mode 0 and Mode 3) with support for 3-byte and 4-byte address switching and Serial Flash Discoverable Parameters (SFDP).
• Data Protection & Security Software and hardware write-protect mechanisms, lockable 3 × 512-byte OTP security sector, volatile status register bits, and read-unique ID support.
• Reliability & Endurance Minimum 100K program/erase cycles per sector or block and typical data retention of 20 years.
• Package & Temperature Available in 8-pin SOP 200 mil package (surface mount) and specified for industrial temperature operation (–40 °C to 85 °C). RoHS compliant.

Typical Applications

• Embedded firmware storage — Store boot code and application firmware with fast Quad I/O read for quicker system boot and code fetch.
• Field upgradeable systems — Uniform 4 KB sectors and software/hardware protection enable selective sector updates and secure firmware patching.
• Industrial control and instrumentation — Industrial temperature range and robust endurance make it suitable for long-life embedded systems.
• External program/data storage — Large density and page-program capability support complex application images and persistent data logs.

Unique Advantages

• High-density storage: 512 M-bit capacity provides ample room for large firmware images and multiple data partitions without external memory stacking.
• Flexible erase granularity: 4 KB uniform sectors and larger block options permit efficient updates and minimize erase time for small patches.
• Quad I/O performance: Up to 133 MHz Quad I/O fast read reduces read latency for boot and code execution compared with standard SPI read speeds.
• Endurance and retention: Minimum 100K program/erase cycles and 20-year data retention support long-term deployment and field updates.
• Robust protection features: Hardware and software write protection plus lockable OTP sector help safeguard code and critical data.
• Industrial-ready packaging: Surface-mount 8-pin SOP 200 mil option and –40 °C to 85 °C rating support rugged system designs.
