• Interface & Performance  SPI serial interface supporting Standard, Dual and Quad SPI. Fast read clock up to 104 MHz for Single/Dual/Quad I/O and up to 133 MHz for Quad I/O fast read.
• Memory Organization  Uniform 4-Kbyte sector architecture (8,192 sectors), plus block and page structures: 1,024 blocks of 32-Kbyte and 512 blocks of 64-Kbyte for flexible erase granularity.
• Program/Erase Speed  High performance program/erase: typical page program time 0.5 ms, sector erase time 40 ms, half-block 200 ms, block erase 300 ms, chip erase 120 s.
• Endurance & Retention  Minimum 100K program/erase cycles per sector or block with typical data retention of 20 years.
• Protection & Security  Software and hardware write protection, default Quad Enable (QE=1), lockable 3×512-byte OTP security sector, Read Unique ID and Replay‑Protected Monotonic Counter (RPMC).
• Power & Low Power  Single power supply operation with low power consumption: typical active current 12 mA and typical power-down current 1 μA.
• Addressing & Compatibility  Supports 3-byte and 4-byte addressing mode switch and Serial Flash Discoverable Parameters (SFDP) signature.
• Package & Temperature  Available in an 8-pin SOP 200 mil body width, surface-mount package; industrial operating range (−40 °C to 85 °C).
• Compliance  All Pb-free packages are RoHS compliant.

Typical Applications

• Industrial controllers  Non-volatile firmware and configuration storage with sector-level protection and high endurance for field updates.
• Embedded systems & IoT devices  Code and data storage requiring compact package, low power standby, and fast SPI read performance for boot and runtime code execution.
• Networking & communications equipment  Boot code and parameter storage where fast read throughput and robust erase/program cycles support reliable field operation.
• Secure storage segments  Lockable OTP sectors, unique ID and RPMC provide mechanisms for device identity and replay-protected counters in secure applications.

Unique Advantages

• Flexible erase granularity: Uniform 4-Kbyte sectors and multiple block sizes enable precise updates and reduced erase overhead during firmware patches.
• Multi-mode SPI performance: Standard, Dual and Quad SPI with up to 133 MHz Quad read capability reduces read latency for critical boot and execution code.
• Robust lifetime and retention: Designed for a minimum of 100K program/erase cycles and typical 20-year data retention for long-term deployments.
• Integrated protection features: Hardware WP# and software write protection plus lockable OTP sector help safeguard code and sensitive data in-system.
• Industrial temperature range: Specified −40 °C to 85 °C operation for deployment in temperature-variable industrial environments.
