Microchip’s PIC18-Q43 family adds more Core Independent Peripherals with an extensive development tool ecosystem to improve real-time control.
The configurable peripherals on the chip have smart interconnection which allows near-zero latency sharing of data, logic inputs or analog signals without additional code. The series is intended for a wide range of real-time control and connected applications, reducing board space, BoM, costs and time to market.
