Microchip PIC18F K42 controllers

The Microchip PIC18F K42 controllers have core independent peripherals (CIPs), high-resolution analog, on-chip direct memory access (DMA) and vectored interrupts for fast processing.

The DMA controller enables data transfers between memory space and peripherals without core processing unit (CPU) involvement, improving system performance and lowering power consumption. When interrupts are required, vectored interrupts provide faster response times with fixed latency reducing software overhead. Code development is also simplified with the user-friendly MPLAB code configurator, making the product well suited to an extensive range of applications and markets, including touch sensing, automotive, industrial control, Internet of Things (IoT), medical and whitegoods.

The product has up to 128 KB Flash and 8 KB RAM. CIPs simplify the implementation of common system functions like sensor interface, signal generation, power conversion, motor control, safety management and system communications. The product features a 12-bit ADC with computation which automates analog signal analysis for real-time system response. The MCUs also include configurable logic cells, low power modes (IDLE, DOZE and peripheral module disable) to reduce power consumption and improved serial communications including UART with support for asynchronous systems, DMX, DALI and LIN protocols along with higher speed, standalone I²C and SPI.
