• Interface & Performance: Serial SPI architecture supporting Standard, Dual and Quad SPI; SPI compatible Mode 0 and Mode 3; Fast Read up to 104 MHz for Single/Dual/Quad I/O.
• Program/Erase Performance: Typical page program time 0.5 ms (500 µs); sector erase ~40 ms typical; half-block ~200 ms, block ~300 ms and chip erase ~60 seconds typical.
• Power: Single power supply operation with full voltage range specified in the datasheet; low active current (~12 mA typical) and very low standby current (~1 µA typical).
• Reliability & Retention: Endurance: minimum 100K program/erase cycles per sector/block; data retention time: 20 years (typical per datasheet).
• Security & Protection: Software and hardware write protection, lockable 3 × 512-byte OTP sectors, Replay-Protected Monotonic Counter (RPMC), Read Unique ID, blank-check bit, and write suspend/resume support.
• Packaging & Temperature: Available in an 8-pin SOP 200 mil package (part-specific); industrial operating temperature range (−40 °C to 85 °C) and surface-mount mounting.
• Standards & Discovery: Supports Serial Flash Discoverable Parameters (SFDP) signature; default Quad Enable (QE=1) and WP#/HOLD# disabled as per device defaults in the datasheet.
• Regulatory: RoHS compliant.

Typical Applications

• Industrial Control: Firmware and configuration storage for PLCs, motor drives and factory automation where industrial temperature range and robust erase/program cycles are required.
• Embedded Systems: Code storage and in-field firmware updates for microcontroller-based products that benefit from Serial SPI and Quad I/O fast read modes.
• IoT and Edge Devices: Non-volatile storage for boot code, device configuration and secure counters in low-power edge devices and sensor gateways.
• Consumer & Commercial Electronics: External program memory for user interfaces, multimedia controllers and feature updates that require uniform sectors and reliable erase/program behavior.

Unique Advantages

• Fast Read Throughput: 104 MHz Fast Read support for Single/Dual/Quad modes reduces boot and code fetch latency in systems that utilize high-speed SPI read paths.
• Flexible Memory Management: Uniform 4-Kbyte sectors and multiple block sizes allow targeted erase/update operations to minimize flash wear and simplify firmware patching.
• Low Idle Power: Typical standby current around 1 µA helps maintain low power consumption during long idle periods without sacrificing active performance.
• Robust Endurance and Retention: Minimum 100K program/erase cycles and 20-year data retention support long-lived products and field-update scenarios.
• Security & Partitioning: Hardware and software write-protect features plus lockable OTP sectors and RPMC provide options for secure storage and protected device regions.
• Industrial-Grade Packaging: Surface-mount 8-pin SOP 200 mil package and −40 °C to 85 °C rating address durability requirements for industrial deployments.
