PIC18F26/45/46Q10
28/40-Pin, Low-Power, High-Performance Microcontrollers
Description
PIC18F26/45/46Q10 microcontrollers feature Analog, Core Independent, and Communication Peripherals
for a wide range of general purpose and low-power applications. These 28/40/44 -pin devices are
2
equipped with a 10-bit ADC with Computation (ADC ) automating Capacitive Voltage Divider (CVD)
techniques for advanced touch sensing, averaging, filtering, oversampling and performing automatic
threshold comparisons. They also offer a set of Core Independent Peripherals such as Complementary
Waveform Generator (CWG), Windowed Watchdog Timer (WWDT), Cyclic Redundancy Check (CRC)/
Memory Scan, Zero-Cross Detect (ZCD), Configurable Logic Cell (CLC), and Peripheral Pin Select
(PPS), providing for increased design flexibility and lower system cost.
