PIC12F and PIC16F Microcontroller Product Family

The PIC12F family in available in small 8-pin packages, while PIC16F variants are offered in 14-pin through 64-pin packages. These family devices are suitable for proportion control (Level 2 integration). Some variants in the PIC16F family have one or more enhanced capture compare PWM (ECCP) modules that can be used to generate references for analog control loops. Built-in ADCs can be used to monitor input/output voltage and current and temperature. Comparators can be used to monitor fault inputs. Communication peripherals like UART, SPI and I2C™ can be used for remote monitoring and control.

.PIC18F and PIC24F Product Family

The PIC18F product family also has an 8-bit CPU and offers extended performance over the PIC16F device family. The PIC18F device family can operate at speeds up to 12 MIPS and has a hardware multiplier for faster calculation of control algorithms. There are variants in the PIC18F family with specialized PWM, ECCP modules.

The PIC24F product family is Microchip’s entry level 16-bit microcontroller, providing a path from the PIC18F to extended performance, program memory and RAM. The PIC24F can operate at speeds up to 16 MIPS and has a hardware multiplier for fast calculation of control algorithms. The PIC24F family offers devices with multiple UART, SPI and I2C serial communication channels for remote monitoring or control. The PIC24F devices also include multiple Input Capture and Output Compare/PWM, comparators and a high-speed 10-bit ADC

16-bit Product Family with Advanced Peripherals for Digital Power Control

Implementing advanced software digital control loops for power applications requires a high performance DSP engine along with specialized peripherals. The high performance CPU and rich peripherals of the dsPIC devices enable solutions that do not require much in the way of external support chips. In addition to the space and cost-saving features that are in the dsPIC® DSC solutions, it also has special features enabling advanced power conversion.

The DSP engine can perform single cycle MAC with data saturation, zero overhead looping and barrel shifting required to support fast control loop execution. These devices include peripherals specifically designed for power conversion. They include peripherals such as a high-speed PWM, ADC and analog comparators that can be tied together using an internal configurable control fabric that enables them to interact directly with one another resulting in stunning performance in digital power applications.
