These are hardware modules designed to execute tasks without constant intervention from the CPU, significantly boosting system efficiency and freeing up processing power for other functions. Key CIPs include:
Complementary Waveform Generator (CWG): Outputs complementary PWM signals with dead-band control, essential for driving half-bridge and full-bridge circuits in motor control and power conversion.
Configurable Logic Cell (CLC): Allows the user to create custom logic functions (AND, OR, NOT, etc.) by interconnecting signals from other peripherals, reducing external component count.
Numerically Controlled Oscillator (NCO): Generates highly precise frequency waveforms, useful for applications like tone generation or LED dimming.
8-bit and 16-bit Timers/Counters: Including Timer0 and Timer1 for various timing and counting operations.
Communication Interfaces: It supports SPI, I2C, and EUSART modules for seamless communication with sensors, memory chips, and other system components.
Furthermore, the microcontroller includes a 10-bit Analog-to-Digital Converter (ADC) with 12 channels, multiple PWM outputs, and hardware-based Capacitive Voltage Divider (CVD) technology for advanced touch sensing interfaces.
