Microchip PIC18LF26K83-I/SP

PIC18LF26K83-I/SP 일반적인 설명

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