PIC18F26K42-I/SO 8-bit Microcontrollers MCU 24 Channel Vector
Interrupts TPA3110D2PWPR
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.
