Product overview

Description

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.

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.

In addition, the P variant supports:

  • External PA/LNA to increase power up to 30 dBm
  • Rx antenna diversity to increase the reach of your final product using several antennas.

  • All features
