Typical Applications

• Industrial Control & Automation — Reliable firmware and configuration storage for controllers and PLCs that operate across −40 °C to 85 °C.
• Embedded Firmware Storage — Primary code storage and in-field firmware updates using uniform sectors and flexible erase/program granularity.
• IoT & Edge Devices — Non-volatile storage for boot code, system images and small data logs where low power standby and fast read performance matter.
• Secure ID & Configuration — Store device-unique IDs and small secure parameters using the lockable OTP sectors and Read Unique ID feature.

Unique Advantages

• High-capacity serial storage: 512 M-bit capacity provides ample non-volatile space for large firmware images and multiple application partitions.
• Flexible SPI I/O modes: Support for Standard, Dual and Quad SPI plus Mode 0/3 operation enables designers to trade off pin usage and throughput.
• Uniform 4 KB sectors: Fine-grained erase control reduces unnecessary erase/program cycles and simplifies firmware update strategies.
• Low-power standby: Typical 2 µA power-down current helps minimize energy consumption in battery-assisted or always-on systems.
• Industrial-grade operation: −40 °C to 85 °C rating and robust endurance (≥100K cycles) make the device suitable for demanding environments.
• Hardware and software protection: WP# pin and software protection combine to let systems selectively safeguard critical code and data regions.
