Introduction

The PIC18-Q41 microcontroller family is available in 14/20-pin devices for sensor and real-time control applications. This analog-focused family features a 12-bit ADC with Computation (ADCC) automating Capacitive Voltage Divider (CVD) techniques for advanced capacitive touch sensing, averaging, filtering, oversampling and threshold comparison, two 8-bit DAC modules and an Operational Amplifier. The family showcases a 16-bit PWM module that provides dual independent outputs on the same time base. Additional features include vectored interrupt controller with fixed latency for handling interrupts, system bus arbiter, Direct Memory Access (DMA) capabilities, UART with support for asynchronous, DMX, DALI and LIN protocols, SPI, I²C, and a programmable 32-bit CRC with Memory Scan. This family also includes memory features such as Memory Access Partition (MAP) to support users in data protection and bootloader applications, as well as Device Information Area (DIA) that stores factory calibration values to help improve temperature sensor accuracy.
