The PIC18(L)F25/26K83 microcontroller family with CAN^TM technology in 28-pins features a 12-bit ADC with Computation (ADC²) automating Capacitive Voltage Divider (CVD) techniques for advanced touch sensing, averaging, filtering, oversampling and threshold comparison. In addition, the product family includes Vectored Interrupt Controller with fixed latency for handling interrupts, System Bus Arbiter, Direct Memory Access capabilities, UART with support for Asynchronous DMX, DALI and LIN transmissions, SPI, I²C, memory features like Memory Access Partition (MAP) to support customers in data protection and bootloader applications, and Device Information Area (DIA) which stores factory calibration values to help improve temperature sensor accuracy.

Features :

Supports CAN 1.2, 2.0A and 2.0B
Six modes of operation
Supports legacy – Fully backward compatibly
Vectored Interrupt (VI) capability – Faster interrupt response time
