Microchip Launches New PIC18 Microcontrollers With Core Independent Peripherals

New PIC18 “K40” Family Offers Intelligent ADC Which Operates Independent to the Core CPU

Microchip® have released the PIC18F “K40” family of microcontrollers (MCUs). The family consists of 10 new devices ranging from 16-128 KB of Flash memory with package options covering 28-64 pins. These cost-optimized 8-bit MCUs are the first PIC18 product family to offer Microchip’s popular Core Independent Peripherals (CIPs).

This results in reduced power consumption, allows for deterministic response time, and decreases firmware development and validation time. 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.

The addition of CIPs to the PIC18F “K40” builds upon the legacy of the successful PIC18F “K20” family. These new devices are cost effective and offer up to 128 KB of Flash, 5V operation, EEPROM and extensive peripheral integration. The devices include a full complement of Core Independent Peripherals for safety-critical applications (CRC/Memory Scan, Windowed Watchdog Timer, and Hardware Limit Timer), up to seven hardware PWMs and multiple communications interfaces. Additionally, the PIC18 “K40” 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.

“Microchip continues to expand our 8-bit portfolio with new on-chip peripherals for both the PIC® and AVR® architectures,” said Steve Drehobl, vice president of Microchip’s 8-bit MCU division. “The PIC18F ‘K40’ family combines large memories with the Core Independent Peripherals and Microchip’s MPLAB® Code Configurator (MCC) to significantly reduce product development time and improve system performance.”
