Frequently Asked Questions
How low can PIC18F46K22-I/ML's supply voltage go, and what clock speed is available at that voltage?
PIC18F46K22-I/ML operates from a 2.3 V minimum supply at 20 MHz, making it suitable for 2-cell alkaline or single-cell LiPo battery systems. At higher voltages approaching 5 V, the device can run at up to 64 MHz for compute-intensive tasks.
What distinguishes the nanoWatt XLP technology in PIC18F46K22-I/ML for IoT sensor applications?
nanoWatt XLP delivers sleep currents in the sub-100 nA range and fast wake-up times under 1 µs, enabling duty-cycled IoT sensors to operate for years on a small battery. This is critical for remote data loggers, wireless sensor nodes, and smart agriculture systems that cannot be serviced frequently.
Does PIC18F46K22-I/ML's QFN-44 package offer any thermal or board-density advantage over a TQFP-44?
Yes. The QFN-44 package has a smaller body and an exposed thermal pad on the bottom, reducing junction-to-board thermal resistance compared to a leaded TQFP-44. This helps dissipate heat when running at 64 MHz in compact IoT or industrial sensor designs with limited airflow.
What is the procurement lead time for PIC18F46K22-I/ML and is this part RoHS compliant?
Factory lead time is approximately 6 weeks, and the part carries a Pb-free (RoHS-compliant) designation, qualifying it for EU, Chinese RoHS, and other lead-free regulatory frameworks. Designers planning production volumes should order 8 to 10 weeks in advance to maintain uninterrupted supply.
