With Quad I/O Fast Read at up to 133 MHz, a uniform 4-Kbyte sector architecture, and industrial temperature operation from -40 °C to 85 °C, this device is suited to firmware/boot storage, field updates and secure configuration storage where performance, endurance and long-term data retention are required.

Key Features

• Capacity & Organization 512 M-bit (65,536 KByte) total capacity; organized as 64M × 8 with 262,144 pages and 256 bytes per programmable page.
• Serial SPI Interface & Modes SPI-compatible interface supporting Mode 0 and Mode 3. Standard, Dual and Quad SPI I/O are supported (CLK, CS#, DI/DO and DQ₂/DQ₃ pins).
• High-speed Read Performance Quad I/O Fast Read operation up to 133 MHz (104 MHz supported for Single/Dual/Quad Fast Read at lower supply range), enabling higher throughput for code and data reads.
• Voltage & Power Single-supply operation across 2.7–3.6 V. Low power characteristics with typical active current ~14 mA and typical power-down current ~2 μA.
• Program/Erase & Endurance Fast program/erase performance with typical page program time ~0.5 ms, sector erase ~40 ms, and chip erase ~120 s. Minimum 100K program/erase cycles per sector and 20-year data retention.
• Uniform Sector Architecture Flexible erase granularity with 16,384 sectors of 4-Kbyte, 2,048 blocks of 32-Kbyte and 1,024 blocks of 64-Kbyte—any sector or block can be erased individually.
• Protection & Security Hardware and software write-protect features, software-configurable protection of all or part of memory, lockable 3×512-byte OTP security sector, and Read Unique ID support.
• Package & Temperature Available in an industrial-grade 8-contact WSON package (8 × 6 mm) and specified for operation from -40 °C to 85 °C. RoHS-compliant packaging.

Typical Applications

• Firmware and Boot Storage Non-volatile storage for system boot code and firmware images, with sector protection to safeguard critical code sections during updates.
• Field Upgradeable Systems Supports page program and individual sector/block erase operations enabling reliable in-field firmware patches and updates.
• Data Storage and Logging Large capacity and 4-Kbyte sector granularity accommodate data segments and logging where non-volatile retention is required.
• Device Identity and Configuration Read Unique ID and lockable OTP sector provide persistent device identity and secure configuration storage.

Unique Advantages

• High-throughput Quad I/O: Quad I/O Fast Read at up to 133 MHz improves read performance for code execution and large data transfers.
• Flexible SPI Modes: Standard, Dual and Quad SPI support enables interface scalability across different host controllers and performance needs.
• Fine-grained Erase Architecture: Uniform 4-Kbyte sectors and multiple block sizes simplify firmware patching and selective data updates.
• Durable Storage: Minimum 100K program/erase cycles per sector and 20-year data retention support long-life deployments.
• Low Power Standby: Typical power-down current of ~2 μA helps reduce system standby power.
• Industrial-ready Packaging: WSON 8×6 mm packaging and -40 °C to 85 °C operating range meet industrial environment requirements.
