PIC18F27/47/57Q43
28/40/44/48-Pin, Low-Power, High-Performance
Microcontroller with XLP Technology
Introduction
The PIC18 Q43 microcontroller family is available in 28/40/44/48-pin devices for real-time control applications. This
family features a 12-bit ADC with Computation (ADC2) automating Capacitive Voltage Divider (CVD) techniques for
advanced capacitive touch sensing, averaging, filtering, oversampling and threshold comparison. This family
showcases a new 16-bit PWM module which 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,
memory features like Memory Access Partition (MAP) to support users in data protection and bootloader applications,
and Device Information Area (DIA), which stores factory calibration values to help improve temperature sensor
accuracy.
