Microcontrollers complete with core independent peripherals

The PIC18F K40 family of MCUs from Microchip consists of 10 devices ranging from 16 to 128KB of flash memory with package options covering 28 to 64 pins. The 8bit MCUs are claimed to be the first PIC18 product family to offer core independent peripherals (CIPs). The devices are suited for a broad range of applications and market segments, including touch sensing, industrial control, consumer, automotive and the IoT.

CIPs are said to provide developers with the ability to accomplish tasks in hardware whilst freeing up the CPU to do other tasks or go to sleep. This results in reduced power consumption, allows for deterministic response time, decreased firmware development and the time need for validation. The family features an A/D converter (ADC2) which, independent of the core, can control data-acquisition and signal-analysis functions required in sensor interface applications, such as capacitive touch sensing.

The devices are said to be cost effective and offer 5V operation, EEPROM and extensive peripheral integration. The devices include CIPs for safety critical applications, up to seven hardware PWMs and multiple communications interfaces. In addition, the family offers intelligent analogue peripherals including Zero Cross Detect, on-chip comparator and ADC2.

The family is supported by the Curiosity High Pin Count board and the company’s software development platforms, including MPLAB Code Configurator, MPLAB IDE, XC8 Complier, and cloud-based IDE MPLAB Xpress.

Package options include UQFN (4 x 4 x 0.5mm), QFN, SOIC, SSOP, TQFP, and DIP packages.
