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 Analog-to-Digital Converter with Computation (ADCC) automating Capacitive Voltage

Divider (CVD) techniques for advanced capacitive touch sensing, averaging, filtering, oversampling and threshold

comparison. This family showcases a new 16-bit Pulse-Width Modulator (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, Universal

Asynchronous Receiver-Transmitter (UART) with support for asynchronous, Digital Multiplex (DMX), Digital

Addressable Lighting Interface (DALI) and Local Interconnect Network (LIN) protocols, Serial Peripheral Interface

(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.
