PIC18-Q20 Compact MCUs with I3C and MVIO
Microchip's PIC18-Q20 14/20-pin, low-power, high-performance microcontroller features eXtreme low-power (XLP) technology
Microchip's PIC18-Q20 microcontroller family is one of the smallest 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 300 ksps ADC with computation for responsive sensor designs. The family features a multivoltage I/O (MVIO) interface with multiple pins powered by VDDIO2 and VDDIO3 that allow these pins to operate at a different voltage domain than the rest of the microcontroller. The family 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, 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. This 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.
