28-Pin, Low-Power, High-Performance Microcontrollers
with XLP Technology
The PIC18(L)F24/25K42 microcontroller family is available in 28-pin devices. This family features a 12-bit ADC with
Computation (ADC2) automating Capacitive Voltage Divider (CVD) techniques for advanced touch sensing, averaging,
filtering, oversampling and threshold comparison, Temperature Sensor, 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.
