• Serial SPI Interface — SPI compatible architecture supporting Standard, Dual and Quad SPI I/O with Mode 0 and Mode 3 operation.
• High-Speed Read — Fast read support: up to 104 MHz for Single/Dual/Quad I/O Fast Read and up to 133 MHz for Quad I/O Fast Read.
• Voltage & Power — Single power supply operation with full voltage range 1.65–1.95 V; low power profile with typical active current ~14 mA and typical power‑down current ~2 μA.
• Uniform Sector Architecture — 16,384 sectors of 4 KB each (also organized as 2,048 blocks of 32 KB and 1,024 blocks of 64 KB) enabling individual sector or block erase operations.
• Program/Erase Performance — Typical page program time ~0.5 ms; sector erase time ~40 ms; half‑block and block erase times ~200 ms and ~300 ms respectively; chip erase ~120 s (typical).
• Reliability — Minimum 100K program/erase cycles per sector/block and data retention time of 20 years.
• Security & Identification — Lockable 3 × 512‑byte OTP security sector and Read Unique ID Number support; supports Serial Flash Discoverable Parameters (SFDP).
• Package & Temperature — Available in an 8‑pin WSON package (5 × 6 mm) for this device; datasheet lists additional package options. Industrial temperature range (−40 °C to 85 °C).
• Standards & Compliance — Pb‑free packages compliant with RoHS; halogen‑free and REACH compliant status indicated for Pb‑free offerings.

Typical Applications

• Embedded firmware storage — Store boot code and application firmware with sector‑level erase and program flexibility to support in‑field updates and code patching.
• Non‑volatile data logging — Use uniform 4 KB sectors and page programming to record and update configuration or sensor data in industrial systems.
• Code shadowing and execute‑in‑place — High read throughput with Quad I/O Fast Read up to 133 MHz supports fast code fetch for performance‑sensitive embedded designs.

Unique Advantages

• Flexible I/O modes: Standard, Dual and Quad SPI support allows designers to scale throughput without changing memory architecture.
• Fine‑grained erase control: 4 KB uniform sectors enable targeted updates and reduce erase‑write overhead compared with larger block‑only devices.
• Industrial readiness: Specified for −40 °C to 85 °C and offered in an 8‑pin WSON surface‑mount package suited for space‑constrained, rugged designs.
• Low standby power: Typical power‑down current of 2 μA helps preserve energy in battery‑powered or low‑power applications.
• Endurance and retention: Minimum 100K program/erase cycles and 20‑year data retention provide long‑term reliability for deployed systems.
