PIC18-Q40 Microcontrollers (MCUs)

To create customized hardware-based logic functions, the four user-configurable Custom Logic peripherals let you specify combinations of signals as inputs to a logic function and internally connect peripherals such as timers, Pulse-Width Modulators (PWMs), serial ports and I/O pins for easy hardware customization. Because the Custom Logic peripheral enables a higher level of integration without the need for any external components, you can reduce your PCB footprint and system costs.

IDLE and DOZE low-power modes allow you to optimize your application for device performance and power consumption. The Peripheral Module Disable (PMD) allows unused peripherals to be turned off individually, further reducing power consumption. 

Peripheral Pin Select (PPS) provides ultimate flexibility when routing digital signals to device pins. With PPS, any digital peripheral can be connected to any I/O pin on the fly for a customized layout. This allows you to maintain layout compatibility with older PIC® MCUs, even as new features are implemented. 

The PIC18-Q40 family features four Direct Memory Access (DMA) controllers to perform data transfers between all memory spaces and peripherals to boost system performance and improve power consumption.

Delivering advanced capabilities beyond those found on standard PWM modules, the integrated, high-resolution 16-bit PWMs allow you to easily vary phase, duty cycle and offset event count with greater precision. They offer dual independent outputs on the same time base, which helps simplify drive control in a variety of applications. The flexible serial communications interface options include a UART with support for Asynchronous, DMX, DALI and LIN protocols, plus higher-speed, stand-alone I2C and SPI modules.

The on-chip intelligent analog peripherals enable you to develop simple, efficient solutions. They include a Zero Cross Detect (ZCD) module, comparators, two 8-bit Digital-to-Analog Converter (DACs) and a 12-bit Analog-to-Digital Converter with Computation (ADCC) that automates Capacitive Voltage Divider (CVD) techniques for implementing advanced touch sensing, averaging, filtering, oversampling and automatic threshold comparison.
