PIC18 MCUs with core independent peripherals

9 November 2016 DSP, Micros & Memory

Microchip announced the PIC18F ‘K40’ family of microcontrollers (MCUs) consisting of 10 new devices ranging from 16 to 128 KB of Flash memory with package options covering 28 to 64 pins. These cost optimised 8-bit MCUs are the first PIC18 product family to offer Microchip’s popular core independent peripherals (CIPs).

CIPs 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 needed for validation.

The PIC18F ‘K40’ features the ADC with computation (ADC²), an intelligent analog-to-digital converter which, independent of the core, can control data-acquisition and signal-analysis functions required in sensor interface applications, such as capacitive touch sensing.

These new devices offer 5 V operation, EEPROM and extensive peripheral integration. They include a full complement of core independent peripherals for safety-critical applications (CR/memory scan, windowed watchdog timer and hardware limit timer), up to seven hardware PWMs and multiple communications interfaces. In addition, the product family offers intelligent analog peripherals including zero cross detect (ZCD), on-chip comparator and ADC². The ADC² handles the signal analysis functions of averaging, filtering, oversampling and automatic threshold comparison independent of the CPU.

The devices are well suited for a broad range of applications and market segments including touch sensing, industrial control, consumer, automotive and the Internet of Things (IoT). The new PIC18F ‘K40’ family is supported by the Curiosity High Pin Count (HPC) board and Microchip’s established software development platforms including MPLAB Code Configurator (MCC), MPLAB IDE, XC8 Complier, and Microchip’s new cloud-based IDE MPLAB Xpress.
