Microchip Technology PIC18-Q71 28/40/44/48-Pin Microcontrollers

Microchip Technology PIC18-Q71 28/40/44/48-Pin Microcontrollers are designed for high bandwidth mixed-signal and sensor applications. The PIC18-Q71 MCUs are an ideal solution for lighting, motor control, and medical market segments.

The analog-focused Microchip PIC18-Q71 MCUs incorporate a 12-bit differential ADC with computation and context switching, two operational amplifiers, a 10-bit Digital-to-Analog Converter (DAC), and two 8-bit DAC modules with buffered outputs and internal connections to other peripherals, and two advanced high-speed analog comparators. Additionally, the devices feature the Analog Peripheral Manager to manage analog peripherals for optimizing power consumption.

The PIC18-Q71 microcontrollers offer the 8-bit virtual port module to interconnect digital peripherals without utilizing external pins.
