The is a popular 28-pin, 8-bit microcontroller often used for low-cost embedded applications. In Proteus, it is used to simulate hardware behavior and verify firmware before moving to a physical PCB. Finding the PIC16F72 in Proteus
If PIC16F72 is insufficient for your simulation needs, consider: pic16f72 proteus library

Missing CLOCK directive or incorrect crystal parameters. Fix: Attach a virtual crystal (from the library, search "CRYSTAL") to OSC1 and OSC2. Then set the processor frequency in Edit Properties to match (e.g., 20MHz). The is a popular 28-pin
