Wi-Fi

This all‑in-one design and capability contribute to reduced costs and enhanced performance, making it an attractive choice for IoT edge devices requiring a single‑chip solution.

ST67W611M1 operates as an IoT connectivity transceiver, with an external STM32 host MCU running applications.

All wireless stacks running on the module, or there is an option for IP on the host.

ST67W611M1 integrates:

• A PCB antenna (version -B), a RF connector (version-U) for external antenna, or version with a dedicated RF pin typically for support of multi-antenna implementations with external RF switch
• 4 MB NOR flash
• 40 MHz high-precision quartz for optimal RF performance
• SMPS functionality and associated bill of material (BOM)
• All needed discrete components to reduce the overall board BOM
• Data interface through SPI
• 32768 Hz internal oscillator. For low-power use cases, two pins are provided to use a 32768 Hz quartz. One pin can also be used to receive an accurate 32768 Hz from the host processor.
