• High‑speed Read: 104 MHz clock rate for Single/Dual/Quad I/O fast read; supports SPI Mode 0 and Mode 3 and configurable dummy cycles for timing flexibility.
• Flexible I/O Modes: Standard, Dual and Quad SPI (CLK, CS#, DI/DO, DQ0–DQ3) with default Quad Enable (QE=1) and WP#, HOLD# disabled by default.
• Program/Erase Performance: Typical page program time 0.5 ms; typical sector erase 40 ms; half‑block and block erase times 200 ms and 300 ms respectively; full chip erase typical 120 s.
• Sector/Block Architecture: Uniform sector architecture with 16,384 sectors of 4 Kbyte; also provided are 2,048 blocks of 32 Kbyte and 1,024 blocks of 64 Kbyte for flexible erase granularity.
• Reliability & Endurance: Minimum 100K program/erase cycles per sector and greater than 20‑year data retention for long‑term storage needs.
• Security & System Features: Lockable 3×512 byte OTP security sector, Read Unique ID, Replay‑Protected Monotonic Counter (RPMC) and SFDP support for device discovery.
• Power Consumption: Low power design with typical active current 24 mA and typical power‑down current 2 µA.
• Voltage & Temperature: Single supply operation with full voltage range 2.7–3.6 V and industrial operating temperature −40 °C to 85 °C.
• Package & Mounting: Surface‑mount 8‑pin WSON package (5×6 mm) suitable for compact industrial boards.

Typical Applications

• Embedded Firmware Storage: Reliable non‑volatile storage for boot code and application firmware in industrial controllers and appliances.
• Industrial Control Systems: Stores configuration, calibration data and firmware images where industrial temperature range and endurance matter.
• Connectivity & IoT Gateways: Holds firmware, security parameters and unique IDs for remote devices requiring robust field updates.
• Consumer & Professional Equipment: Firmware and parameter storage for devices that benefit from Quad SPI read performance and low power standby.

Unique Advantages

• High‑density Non‑volatile Storage: 512 Mbit capacity with 256‑byte programmable pages enables large firmware images and data sets in a compact footprint.
• Fast, Flexible Read Modes: Single/Dual/Quad SPI at 104 MHz allows designers to scale read throughput to system needs without changing package.
• Granular Erase Control: 4 Kbyte uniform sectors and multiple block sizes let you minimize erase scope during in‑field updates to reduce wear.
• Field‑oriented Reliability: 100K program/erase cycles and >20‑year data retention support long product lifecycles in industrial deployments.
• Low Standby Power: Typical 2 µA power‑down current conserves energy in battery‑backed or low‑power systems.
• Compact Industrial Package: 8‑pin WSON (5×6 mm) offers a small board footprint while maintaining robust thermal and mechanical characteristics for industrial use.
