Frequently Asked Questions

What is the maximum clock frequency of PIC18F8493-I/PT, and how does it impact real-time control tasks?

The PIC18F8493-I/PT operates at up to 40 MHz, delivering 10 MIPS of instruction throughput, which is sufficient for real-time PID loops, sensor polling, and multi-channel communication tasks in industrial embedded systems.

How does the 80-pin TQFP package of PIC18F8493-I/PT benefit high-I/O embedded designs?

The TQFP-80 package provides 80 pins in a compact square SMT footprint, giving designers access to numerous GPIO, ADC inputs, and peripheral pins without requiring external I/O expanders, reducing BOM cost and PCB area.

Is PIC18F8493-I/PT suitable for industrial temperature environments, and what compliance markings does it carry?

The 'I' temperature suffix indicates industrial-grade operation, typically rated from -40°C to +85°C, and the part carries a lead-free (Pb-free) code, confirming RoHS compliance for designs targeting global regulatory markets.

What lead time should procurement teams plan for when sourcing PIC18F8493-I/PT in volume?

The factory lead time for PIC18F8493-I/PT is approximately 5 weeks, so procurement teams should plan buffer stock or place blanket orders at least 6 to 8 weeks ahead of production schedules to avoid line stoppages.
