Key Features

• Memory & Organization 512 M-bit (65,536 KByte) capacity with 262,144 pages and 256 bytes per programmable page; uniform 4-Kbyte sectors with 16,384 sectors for fine-grained erase and protection.
• Interface & Read Performance SPI-compatible serial interface supporting Standard, Dual and Quad I/O; 104 MHz clock rate for Single/Dual/Quad I/O Fast Read and up to 133 MHz for Quad I/O Fast Read (per ordering option).
• Program & Erase Page program typically 0.5 ms; sector erase typically 40 ms, half-block 200 ms, block erase 300 ms and chip erase typically 120 seconds—enabling high-performance program/erase cycles.
• Power Single-supply operation across the full voltage range; low active and standby currents with typical active current around 24 mA and typical power-down current around 2 µA.
• Reliability & Endurance Minimum 100K program/erase cycles per sector/block and typical data retention of 20 years for long-term storage reliability.
• Security & Management Lockable 3×512-byte OTP security sector, Replay-Protected Monotonic Counter (RPMC), and support for Serial Flash Discoverable Parameters (SFDP) and Unique ID readout.
• Packaging & Temperature Supplied in a 16-pin SOP 300mil surface-mount package; industrial operating temperature range (–40 °C to 85 °C) and RoHS-compliant Pb-free construction.

Typical Applications

• Firmware and System Code Storage Stores boot code and firmware with sector-level protection to enable safe in-field updates and selective code patching.
• Configuration and Calibration Data Retains system parameters and calibration tables with long data-retention characteristics for industrial controllers and instrumentation.
• Embedded and Industrial Devices Provides non-volatile program/data storage for industrial controllers, IoT gateways, and embedded appliances requiring industrial temperature range and durable endurance.

Unique Advantages

• Flexible SPI Modes: Standard, Dual and Quad SPI support enables designers to scale read bandwidth to match system performance needs.
• Fine-Grained Erase and Protection: 4-Kbyte uniform sectors and per-sector/block erase allow selective updates and software-controlled protection of critical code regions.
• Fast Program/Erase Performance: Typical page program time of 0.5 ms and sector erase around 40 ms reduce maintenance windows during field updates.
• Industrial Temperature and Robust Endurance: –40 °C to 85 °C rating combined with minimum 100K program/erase cycles supports long-term deployment in demanding environments.
• Low Power Standby: Typical power-down current of 2 µA helps minimize energy use in battery-backed or low-power systems.
• Security and Identification: On-chip OTP, unique ID and RPMC features enable tamper-resistant storage and secure device identification.
