• Serial SPI Architecture — Supports Standard, Dual and Quad SPI with Single/Dual/Quad I/O Fast Read instructions.
• High‑Speed Read — Up to 104 MHz clock rate for Single/Dual/Quad I/O Fast Read; higher quad‑I/O modes referenced in the series documentation for 3.0–3.6V variants.
• Program & Erase Performance — Typical Page Program time 0.6 ms; Sector Erase (4 KB) typical 50 ms; 32 KB block erase 120 ms typical; 64 KB block erase 150 ms typical; chip erase typical 15 seconds.
• Endurance & Retention — Minimum 100K program/erase cycles per sector and 20 years data retention.
• Power Characteristics — Low-power operation with typical active current ~5 mA and typical power-down current ~1 µA.
• Write Protection & Security — Software and hardware write protection, WP# pin enable/disable, plus three OTP lockable 512‑byte security sectors and Read Unique ID.
• Memory Flexibility — Uniform Sector Architecture: 1,024 sectors of 4 KB, 128 blocks of 32 KB and 64 blocks of 64 KB allowing individual sector or block erase.
• Package & Temperature — Available in 16-pin SOP 300mil; industrial operating temperature range −40 °C to 85 °C.
• Standards & Discovery — Supports Serial Flash Discoverable Parameters (SFDP) and burst read with wrap options (8/16/32/64 byte).

Typical Applications

• Industrial Embedded Systems — Non-volatile storage for firmware, configuration and system parameters in industrial controllers and instrumentation.
• Communications & Networking — Storage of boot code, device configuration and system images where reliable serial flash is required.
• Consumer & Professional Electronics — Flash storage for code and data in devices that require sector/block erase flexibility and long data retention.

Unique Advantages

• Flexible I/O Modes — Single/Dual/Quad SPI support enables designers to balance pin usage and throughput according to system needs.
• Granular Erase Options — Uniform 4 KB sectors plus 32 KB/64 KB block erase enable targeted updates and reduce unnecessary wear on other regions.
• Fast Read Performance — 104 MHz Fast Read reduces code and data fetch latency in systems where read throughput matters.
• Robust Protection — Hardware WP# and software protection modes plus OTP lockable security sectors provide multiple layers of write control and security.
• Industrial Readiness — Industrial temperature rating (−40 °C to 85 °C) and Pb‑free packaging options support deployment in demanding environments.
• Low Power Operation — Typical active and power-down currents help minimize system power consumption during active and idle periods.
