PIC18(L)F26/27/45/46/47/55/56/57K42
28/40/44/48-Pin, Low-Power High-Performance
Microcontrollers with XLP Technology
Description
The PIC18(L)F26/27/45/46/47/55/56/57K42 microcontrollers are available in 28/40/44/48-pin devices. These devices
feature 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.
