Overview

The PIC18F24K42-I/SO is a high-performance 8-bit microcontroller featuring 16KB of Flash and a rich set of Core Independent Peripherals (CIPs). It is specifically designed for functional safety applications, integrating hardware features that reduce software overhead for safety-critical tasks while operating at speeds up to 64MHz.

Why Choose This Part

The inclusion of Dual DMA controllers and a Vectored Interrupt controller significantly improves system response time and reduces CPU load. It features a wide operating voltage of 2.3V to 5.5V and hardware-based automated signal monitoring, making it highly reliable in electrically noisy environments.

Applications

Functional Safety Systems
Utilizes hardware CRC, Windowed Watchdog Timer (WWDT), and Memory Access Partitioning (MAP) to meet safety standards with minimal CPU intervention.
Sensor Interfacing
Leverages the 24-channel 12-bit ADC with Computation (ADC2) and two DMA controllers to automate data acquisition and filtering.
Industrial Control
Provides robust I2C, SPI, and UART communication for motor control and factory automation modules requiring high noise immunity.
Power Management
Employs eXtreme Low Power (XLP) technology for battery-operated devices needing long standby times with periodic wake-ups.

Getting Started

Development is primarily supported through Microchip's MPLAB X IDE and the XC8 C Compiler. For rapid prototyping, use the MPLAB Code Configurator (MCC) to graphically initialize the Core Independent Peripherals and DMA channels. Hardware debugging is typically performed using the MPLAB PICkit 4 or ICD 4 in-circuit debuggers.
