Device Overview

Summary

Designed for fast, reliable real-time control applications, PIC18 Q43 MCUs feature a rich set of configurable peripherals, intelligent analog peripherals, large Flash/RAM/EEPROM memories and 5V operation for increased noise immunity.  The hardware-based Core Independent Peripherals offload timing-critical and core-intensive functions from the CPU allowing it to focus on critical tasks within the system. These 28-, 40- and 48-pin devices are also equipped with a 12-bit ADC with computation, 16-bit PWMs which provides dual outputs on the same timebase, Direct Memory Access capabilities, Configurable Logic Cells (CLCs) and 5 UARTS  for improved system efficiency and flexibility for a variety of applications.

Additional Features
  • Six Direct Memory Access (DMA) Controllers:
    • Hardware and software triggered data transfers
  • Vectored Interrupt (VI) Capability - Faster interrupt response time
    • Selectable high/low priority
    • Fixed interrupt latency of three instruction cycles
    • Programmable vector table base address
    • Backwards compatible with previous interrupt capabilities
  • Memory Access Partition (MAP): The Program Flash Memory can be partitioned into:
