PIC18(L)F25/26K83
28-Pin, Low-Power, High-Performance Microcontrollers
with CAN Technology
Description
The PIC18(L)FXXK83 is a full-featured CAN product family that can be used in automotive and industrial applications.
The multitude of communication peripherals found on the product family, such as CAN, SPI, two I
2
Cs, two UARTs, LIN,
DMX, and DALI can handle a wide range of wired and wireless (using external modules) communication protocols for
intelligent applications. This family includes a 12-bit ADC with Computation (ADC
2
) extensions for automated signal
analysis to reduce the complexity of the application. This, combined with the Core Independent Peripherals integration
capabilities, enables functions for motor control, power supply, sensor, signal and user interface applications.
