• Memory Management  Uniform sector architecture with 16,384 sectors of 4-Kbyte, 2,048 blocks of 32-Kbyte and 1,024 blocks of 64-Kbyte; supports individual sector/block erase and full chip erase.
• Package & Temperature  Surface-mount 8-contact WSON package (8 × 6 mm) and industrial operating temperature range (−40 °C to 85 °C).

Typical Applications

• Embedded Firmware Storage  Non-volatile storage for boot code and firmware images where in-field updates and high read throughput are required.
• Industrial Control  Program and configuration storage in industrial controllers that require extended temperature range and robust program/erase endurance.
• IoT & Edge Devices  Local code and parameter storage for edge appliances and IoT gateways that benefit from a compact SMD package and low power standby.
• Secure Data & Identifiers  On‑board unique ID, RPMC and lockable OTP sector support device identity, secure counters and small secure data storage.

Unique Advantages

• High-Speed SPI Read Performance  104 MHz fast read capability enables quicker boot times and faster code fetch for latency-sensitive embedded systems.
• Flexible I/O Modes  Standard, Dual and Quad SPI support allows designers to scale throughput without changing the memory family.
• Granular Memory Protection  Uniform sectors and software/hardware write-protect features let systems protect firmware regions while permitting selective updates to other areas.
• Industrial Robustness  Industrial temperature rating and a durable program/erase endurance (≥100K cycles) support long-term deployment in demanding environments.
• Compact, Surface-Mount Package  8‑contact WSON (8 × 6 mm) offers a small footprint for space-constrained PCBs while maintaining thermal and mechanical stability.
