Frequently Asked Questions
At what minimum supply voltage can PIC18LF452-I/PT operate for low-power applications?
PIC18LF452-I/PT operates at a minimum supply voltage of 2 V when clocked at 4 MHz. This wide voltage range makes it suitable for battery-powered sensor nodes and portable instruments that need to draw down battery capacity while maintaining microcontroller operation.
What clock frequency does PIC18LF452-I/PT support and how does it compare to PIC16 family devices?
PIC18LF452-I/PT supports a maximum clock frequency of 40 MHz on its 8-bit PIC18 core, which is higher than many PIC16 devices rated at 20 or 32 MHz. The PIC18 architecture also provides a more efficient instruction set with a larger instruction word for more compact code.
How many pins does the TQFP-44 package of PIC18LF452-I/PT provide for I/O expansion?
PIC18LF452-I/PT is housed in a 44-pin TQFP-44 package with a 10 x 10 mm body and 1 mm height. This provides 33 or more usable GPIO pins for connecting sensors, displays, and communication peripherals in space-efficient SMT designs.
Is PIC18LF452-I/PT suitable for designs requiring RoHS and lead-free manufacturing compliance?
Yes. PIC18LF452-I/PT carries a Pb-free code designation, confirming RoHS compliance for use in end products targeting the EU and other markets with environmental manufacturing restrictions. The lead-free TQFP-44 package is compatible with standard Pb-free solder reflow profiles.
