MCUs optimized for closed-loop control applications
The PIC and AVR MCUs’ architectures make these devices optimized for implementing closed-loop control, enabling systems to offload the Central Processing Unit (CPU) to manage more tasks and save power. A key advantage of the PIC18 Q10 and ATtiny1607 MCUs are the CIPs that independently manage tasks and reduce the amount of processing required from the CPU. System designers can also save time and simplify design efforts with the hardware-based CIPs, which significantly reduce the amount of software that needs to be written and validated. Both families have features for functional safety and operate up to 5V, increasing noise immunity and providing compatibility with the majority of analogue output and digital sensors.
The ATtiny1607 family comes in a 3x3mm 20-pin QFN package for space-constrained closed-loop control systems such as hand-held power tools and remote controls. In addition to the integrated high-speed Analogue-to-Digital Converter (ADC) that provides faster conversion of analogue signals resulting in deterministic system response, the devices provide improved oscillator accuracy, allowing designers to reduce external components and save costs.
Among the CIPs in the PIC18 Q10 family are the Complementary Waveform Generator (CWG), which simplifies complex switching designs, and an integrated Analogue-to-Digital Converter with Computation (ADC2) that performs advanced calculations and filtering of data in hardware without any intervention from the core. CIPs such as these allow the CPU to execute more complex tasks, such as Human Machine Interface (HMI) controls, and remain in a low-power mode to conserve power until processing is required.
