The CI13LC series chip integrates the self-developed brain neural network processor BNPU V3.5 and CPU core by Chipintelli. The system clock frequency can reach 210MHz, with up to 288KByte of SRAM built-in. It also integrates PMU power management unit and RC oscillator, as well as single channel high-performance low-power Audio codec and multiple peripheral control interfaces such as UART, IIC, PWM, GPIO, etc. It supports speech recognition and noise reduction, and can provide the most cost-effective intelligent speech solution for small appliances, lighting, toys and other products.
