Microchip announced its newest family of 8- to 16-bit MCUs: the PIC18F "K42". The family, comprised of 10 products, boasts the largest total memory of previously manufactured MCUs.

The PIC18F "K42" family of 8-bit MCUs includes a high-speed internal oscillator, analog peripherals, and direct memory access (DMA). The DMA controller enables data transfers between memory space and peripherals without CPU involvement. The PIC18F "K42" family is a good choice for a range of applications, including touch sensing, automotive, industrial control, IoT, and medical devices.

Like other Microchip products, the PIC18F "K42" family is supported by Microchip's MPLAB Code Configurator (MCC), a free software plug-in that provides a graphical interface for hardware configuration, and the Curiosity platform. The MCC works alongside Microchip's other development environments: MPLAB X IDE and MPLAB Xpress IDE.
