PIC18LF47K42-ISLASHP中文资料微芯科技数据手册PDF规格书

描述 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.
