Key Features

• Memory Capacity & Organization 128 M-bit serial flash organized as 16M × 8 with 65,536 pages and 256 bytes per programmable page; uniform sector architecture with 4 KB sectors (4,096 sectors), 512 blocks of 32 KB and 256 blocks of 64 KB.
• High-Speed SPI Interface Supports Standard, Dual and Quad SPI; Fast Read up to 104 MHz for Single/Dual/Quad I/O to accelerate code and data access.
• Program & Erase Performance Typical page program time 0.5 ms, sector erase time 40 ms, half-block erase 200 ms, block erase 300 ms and chip erase ~60 seconds, enabling efficient in-system updates.
• Power and Consumption Low power operation with typical active current ~12 mA and typical standby current ~1 μA, suitable for power-conscious embedded designs.
• Reliability & Data Retention Endurance of at least 100K program/erase cycles per sector and typical data retention of 20 years for long-lived deployments.
• Security & Protection Software and hardware write protection, lockable 3 × 512-byte OTP sectors, write suspend/resume, blank check bit, Replay-Protected Monotonic Counter (RPMC), and Read Unique ID support.
• Voltage & Interface Signals Serial SPI interface with CLK, CS#, DI (DQ0), DO (DQ1), and optional DQ2/DQ3 for Dual/Quad modes; device supports SPI modes 0 and 3 as part of its serial interface architecture.
• Package & Temperature Surface-mount 8-pin WSON 5×6 mm package and industrial operating temperature range of −40 °C to 85 °C. RoHS compliant.

Typical Applications

• Industrial Control Firmware and parameter storage for PLCs, motor drives, and factory automation equipment where sector-level update and long retention are required.
• Embedded Firmware Storage Non-volatile code and configuration storage for microcontroller-based systems that need in-field updates and secure protection of critical code regions.
• Communications & Networking Boot code and configuration storage in industrial routers, gateways, and IoT connectivity modules that benefit from fast SPI read performance.
• Data Logging & Instrumentation Storage of calibration data, logs and operational parameters in measurement instruments and dataloggers operating across industrial temperatures.

Unique Advantages

• Fast SPI Read Performance 104 MHz Fast Read enables quicker boot and code fetch cycles, improving system responsiveness.
• Flexible I/O Modes Standard, Dual and Quad SPI support provides designers flexibility to trade off pin usage and throughput for different system requirements.
• Uniform Sector Architecture 4 KB uniform sectors and the ability to erase individual sectors or blocks simplify firmware updates and reduce erase-impact on unrelated data.
• Robust Data Endurance and Retention Minimum 100K program/erase cycles and 20-year retention provide longevity for deployed systems.
• Low Standby Power Typical standby current ~1 μA helps minimize power draw in systems with infrequent write/read activity.
• On-chip Protection & Security Features Software/hardware write protection, lockable OTP, RPMC and unique ID support help protect sensitive code and system counters.
