Key Features

• Memory Capacity & Organization — 512 Mbit total capacity arranged as 64M × 8 with 256-byte programmable pages and 262,144 pages for fine-grained programming.
• High-speed Read — Fast Read support up to 104 MHz for Single/Dual/Quad I/O and up to 133 MHz for Quad I/O Fast Read.
• Voltage Range — Single power-supply operation across a full 1.65–1.95 V range for low-voltage system compatibility.
• Program & Erase Performance — Typical page program time ~0.5 ms; typical sector erase ~40 ms; half-block erase ~200 ms; block erase ~300 ms; full-chip erase ~120 s.
• Power Consumption — Low active current (typical 14 mA) and low power-down current (typical 2 μA) for energy-conscious designs.
• Uniform Sector Architecture — 16,384 sectors of 4 KB, 2,048 blocks of 32 KB and 1,024 blocks of 64 KB enabling per-sector or per-block erase operations.
• Write Protection & Security — Software and hardware write protection options, lockable 3 × 512-byte OTP sector, and volatile status register bits for control.
• Endurance & Retention — Minimum 100K program/erase cycles per sector and typical data retention of 20 years.
• Package & Temperature — Supplied in an 8-pin WSON (5 × 6 mm) package; industrial temperature range (−40 °C to 85 °C).

Typical Applications

• Embedded Firmware Storage — Reliable non-volatile storage for boot code and firmware images with sector-level erase and fast page program capability.
• Consumer & Industrial IoT Devices — Stores configuration, authentication data and updates with low standby power and SW/HW protection.
• Communications Equipment — Holds bootloaders, reference data and field-upgradeable firmware using Quad I/O fast read for quick code fetch.
• Industrial Control Systems — Industrial temperature operation and robust endurance for application-critical program and data storage.

Unique Advantages

• Flexible SPI Modes: Standard, Dual and Quad SPI support lets designers scale read throughput without changing memory architecture.
• Fine-Grained Erase Control: Uniform 4 KB sectors and multiple block sizes enable targeted updates and reduce unnecessary erase/write cycles.
• Low-Voltage Operation: 1.65–1.95 V single-supply operation supports low-power system designs and simplifies power rail requirements.
• Durable Data Retention: 100K P/E cycles and 20-year retention provide lifecycle predictability for long-lived products.
• Industrial Ready: Industrial temperature rating and small 8-pin WSON package simplify board-level integration for space-constrained designs.
• Security & Protection: Hardware and software protection features plus OTP locking help safeguard critical code and data.
