Microchip Technology PIC18-Q20 Microcontrollers

Microchip Technology PIC18-Q20 Microcontrollers are one of the smaller PIC18 product families available in 14/20-pin devices for sensor-interfacing, real-time control, and communication applications. This family showcases the Improved Inter-Integrated Circuit® (I3C) Target module with a higher communication rate and a 10-bit 300ksps ADC with Computation for responsive sensor designs. The family features a MultiVoltage I/O (MVIO) interface with multiple pins powered by V_DDIO2 and V_DDIO3, allowing these pins to operate at a different voltage domain than the rest of the microcontroller. The Microchip Technology PIC18-Q20 also features the 8-bit Signal Routing Port module to interconnect digital peripherals without using external pins. Additional features include a vectored interrupt controller with fixed latency for handling interrupts, a system bus arbiter, Direct Memory Access (DMA) capabilities, UART with support for asynchronous, DMX, DALI, and LIN protocols, SPI, I²C, and a programmable 32-bit CRC with memory scan. The Microchip Technology PIC18-Q20 family also includes Memory Access Partition (MAP) and SAFLOCK to support users in bootloader applications. SAFLOCK allows one-time programmability of the Storage Area Flash (SAF). The Device Information Area (DIA) stores factory calibration values to help improve temperature sensor accuracy.
