Ideal for applications that use closed-loop control, a key advantage of using 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 required to write and validate. Both families have features for functional safety and operate up to 5V, increasing noise immunity and providing compatibility with the majority of analog output and digital sensors.

Offered in a compact 3 x 3 mm 20-pin QFN package, the new ATtiny1607 family is optimized for space-constrained closed-loop control systems such as handheld power tools and remote controls. In addition to the integrated high-speed Analog-to-Digital Converter (ADC) that provides faster conversion of analog signals resulting in deterministic system response, the devices provide improved oscillator accuracy, allowing designers to reduce external components and save costs.

Among CIPs in the PIC18 Q10 family are the Complementary Waveform Generator (CWG) peripheral, which simplifies complex switching designs, and an integrated Analog-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.

“We continue to see increased demand for flexible PIC and AVR microcontrollers in all kinds of embedded control applications,” said Steve Drehobl, vice president of Microchip’s 8-bit MCU business unit. “By focusing on the challenges faced by closed-loop control system designers, we’ve been able to offer them unprecedented ease of use and performance with the PIC18 Q10 and ATtiny1607 families.”
