UWP5661
Overview¶
UWP5661 is a highly integrated 2-in-1 connectivity single chip which offers the lowest RBOM in the industry for smart home, IoT, industrial control and automotive applications.
This chip includes 2.4GHz and 5GHz WLAN IEEE802.11 a/b/g/n/ac 2x2 MU-MIMO 20/40/80 MHz VHT R2 MAC/PHY/Radio, Bluetooth 5 with supporting high power mode, mesh, direction finding and long range. Additionally, this radio-on-chip integrates power amplifiers, receive low noise amplifiers and RF TR switch.
This chip includes two ARM Cortex-M4 processors. One is used for offloaded Wi-Fi software and Bluetooth controller. The other is used for application processor.
UWP5661 also supports interface including SFC, JTAG, I2S, UART and I2C.
