PIC18F K42 MCU family. Source: Microchip. Microchip’s PIC18F K42 family, which combines an extensive array of Core Independent Peripherals (CIPs), high-resolution analog, on-chip Direct Memory Access (DMA) and vectored interrupts for fast processing, is now available. 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 PIC18F K42 family suited for an extensive range of applications and markets, including touch sensing, automotive, industrial control, Internet of Things (IoT), medical and white goods.
The PIC18F K42 family features reportedly the largest total memory of any 8-bit PIC® MCU with 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 PIC18F K42 features a 12-bit ADC with computation that 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.
