VC7xxx系列是一款高度集成的無線MCU,專為物聯網應用設計。 它集成了Cortex-M3 MCU,高性能 sub-GHz 無線,Flash、SRAM 記憶體,各種接口(例如 UART、SPI、I2C、PWM) 與多種輔助功能(例如 ADC、高精度計時器),支持低功耗的省電模式。 嵌入式的 sub-GHz 無線收發器完全符合IEEE802.15.4g/x標準。它集成了高性能 LNA 和 PAs (13dBm or 20dBm) 以實現低功耗和長距離無線連結。 先進的DSP技術確保VC7xxx在同類產品中提供最佳的通信系統性能,例如強大的鏈路預算,極高的ACI抑制率等。
其中VC7000可協助客戶為自己選擇的MCU添加無線連結功能,VC7200為中小型物聯網應用提供網狀網路連接能力和 Open-CPU,而VC7300(相容Wi-SUN FAN1.0)和VC7351(相容Wi-SUN FAN1.1)則支持大規模工業物聯網應用,例如智能電錶。
