This piece compares hardware CIPs against software-emulated equivalents across three categories: timers (hardware vs. software-defined vs. external RTC), serial communication (hardware modules vs. bit-banging), and discrete logic (external gates/FPGAs/CPLDs vs. on-chip CLC/CCL/CLB). Key trade-offs include precision and bandwidth for hardware versus flexibility and pin-independence for software. The configurable logic block (CLB) on PIC18-Q35 MCUs is highlighted as a middle ground — essentially a small FPGA embedded in the MCU. The guidance helps engineers choose the right MCU by balancing available CIPs with software implementations to control cost while meeting application requirements. ## Full article daily.dev links to this article rather than hosting it.
