Frequently Asked Questions
What is the maximum clock frequency of PIC18F2420-I/SO and how does it affect processing throughput?
The PIC18F2420-I/SO operates at up to 40 MHz, delivering 10 MIPS throughput on its 8-bit PIC18 core. At 40 MHz, the device can execute straightforward control loops and sensor polling tasks well within timing budgets for embedded applications like HVAC controllers and consumer electronics.
How many ADC channels does the PIC18F2420-I/SO have, and what is the resolution?
The PIC18F2420-I/SO includes a 10-bit ADC with multiple analog input channels, enabling direct digitization of sensor voltages without external converters. The 10-bit resolution provides 1024 discrete levels across the reference range, adequate for temperature sensors, potentiometers, and light sensors in typical 8-bit embedded designs.
Is the PIC18F2420-I/SO RoHS compliant, and what is the package lead time?
Yes, the PIC18F2420-I/SO carries a Pb-free RoHS-compliant rating and ships in a 28-pin SOIC package with a factory lead time of approximately 1 week. The short lead time means production planners can maintain lean inventory while still ensuring timely delivery of the 8-bit PIC18 microcontroller for assembly runs.
For a battery-powered sensor node, why might PIC18F2420-I/SO be chosen over a higher-end microcontroller?
For a battery-powered node sampling at low rates, the PIC18F2420-I/SO offers a cost-effective 8-bit PIC18 solution with 16 KB Flash, 768 bytes RAM, and sleep modes that reduce current consumption well below 1 mA in idle states. The 40 MHz maximum clock allows quick wake-wake-process-sleep cycles, extending battery life compared to continuously active higher-power MCUs.
