The chip achieves high integration with simplified peripherals, requiring only one crystal oscillator and a few resistors and capacitors for the solution. It supports BLE 4.1 wireless communication protocol, enabling bidirectional communication with mini-programs. It also supports 2.4GHz communication.
The chip provides a wider range of IO interfaces, compatible with both 3.3V and 5V. It operates at a high clock frequency (240MHz) and offers larger SRAM, ensuring sufficient computing power for the main control applications.
With excellent noise resistance, the chip achieves an 85% recognition rate and 90% wake-up rate in noisy environments up to 75dB. It supports a maximum of 150 command words.
