• Addressing & Identification Supports 3-byte/4-byte address switching, Serial Flash Discoverable Parameters (SFDP), and Read Unique ID Number.
• Package & Temperature Available in an 8-pin SOP 200 mil package and specified for industrial temperature operation (−40 °C to 85 °C).

Typical Applications

• Embedded firmware storage — Reliable code storage and in-field firmware patching where sector-level protection and fast read performance are required.
• System boot and code shadowing — High-speed Quad I/O read up to 133 MHz supports fast boot and execute-in-place scenarios.
• Data logging and parameter storage — Uniform 4 KB sectors and erase/program flexibility enable reliable segmented data storage and updates.
• Industrial control systems — Industrial temperature range and robust endurance support deployment in industrial embedded designs.

Unique Advantages

• High-throughput Quad I/O: 133 MHz Quad I/O Fast Read enables faster code fetch and bulk read operations compared to standard SPI reads.
• Fine-grained protection: Uniform 4 KB sectors and software/hardware write-protect mechanisms let you protect critical code while updating other regions.
• Field update-friendly: Fast page program and individual sector erase times simplify firmware update strategies with minimal downtime.
• Low-power operation: Single-supply design with low active and power-down currents reduces system power consumption in active and standby modes.
• Durable and long-lived: 100k program/erase cycle endurance and 20-year data retention support long-term deployed applications.
• Security and discoverability: Lockable OTP sector plus SFDP and unique ID support simplifies device identification and secure data storage.
