• Serial SPI Interface — Supports Standard, Dual and Quad SPI modes with CLK, CS#, DI/DO (DQ0/DQ1) and DQ2/DQ3 signals; SPI Mode 0 and Mode 3 supported.
• High-Speed Read — Up to 104 MHz clock rate for Single/Dual/Quad I/O Fast Read operations, enabling fast code execution and data transfers.
• Program / Erase Performance — Typical page program time 0.5 ms; typical sector erase time 40 ms; supports page program of 1–256 bytes.
• Uniform Sector Architecture — 4,096 sectors of 4-Kbyte with flexible erase options (sector, half-block, block, or full chip) and individual sector/block erase capability.
• Durability & Retention — Minimum 100K program/erase cycles per sector and typical data retention of 20 years.
• Low Power — Typical active current ~8 mA and typical power-down current ~0.1 µA for efficient standby operation.
• Security & Protection — Software and hardware write protection, lockable 3 × 512-byte OTP security sector, volatile status register bits, and replay-protected monotonic counter (RPMC).
• Package & Temperature — Available in 8-pin SOP 200 mil package; surface-mount mounting; industrial operating temperature range −40 °C to 85 °C.
• Standards & Compatibility — Supports Serial Flash Discoverable Parameters (SFDP) and provides Read Unique ID Number; default Quad Enable (QE=1).
• Regulatory — RoHS compliant.

Typical Applications

• Industrial Control — Non-volatile program and data storage for PLCs, motor controllers and factory automation requiring robust sector protection and industrial temperature range.
• Embedded Systems & Firmware Storage — Reliable storage for boot code, firmware images and field updates with support for individual sector erase and secure OTP areas.
• Networking & Communications — Fast SPI read and Quad I/O support for firmware and configuration storage in communications modules and network appliances.
• IoT & Edge Devices — Low-power standby and high endurance for remote devices that need long retention and secure update mechanisms.

Unique Advantages

• High-speed Quad SPI I/O: 104 MHz single/dual/quad read capability shortens firmware load and boot times.
• Flexible erase granularity: 4-Kbyte sectors and multiple block sizes enable targeted updates and reduce erase/program overhead.
• Long-term reliability: 100K program/erase cycles and 20-year data retention support extended product lifecycles.
• Low-power operation: Typical 8 mA active current with very low power-down current (~0.1 µA) to conserve energy in standby scenarios.
• Industrial-ready packaging: 8-pin SOP 200 mil surface-mount package with −40 °C to 85 °C rating for harsh environments.
• Integrated protection features: Software/hardware write protection, lockable OTP sector and RPMC for secure update and storage workflows.
