PIC18LF66K80 microcontroller for low-voltage

The PIC18LF66K80-IPT is a new microcontroller supplied in a 64-pin TQFP package. It targets engineers building battery-powered or energy-harvesting devices that need an 8-bit core with integrated peripherals. The part suits designs where code density and peripheral integration matter more than raw throughput.

TQFP64 package suits automated surface-mount

The thin quad flat pack with 64 leads fits standard reflow processes and allows visual inspection of solder joints. Its lead pitch supports typical PCB design rules without requiring exotic stack-ups. The surface-mount format enables high-density layouts for compact control boards.

Verify supply voltage range

Confirm that your design operates within the low-voltage range implied by the LF designation and that the on-chip peripherals match your I/O needs. Check that the 64-pin footprint matches your existing PCB land pattern. Ensure your toolchain supports this specific device variant for programming and debug.

Questions about this item

What does the 64-pin TQFP package require for board layout?

The 64-pin TQFP package needs a 64-position footprint with matching pin pitch and pad geometry on the PCB.

What physical clearance does the TQFP64 body need above the board?

The TQFP64 body sits close to the board surface, so allow enough vertical clearance for the package height and any heatsink or enclosure.

How is the PIC18LF66K80-IPT programmed after soldering, and what step is often missed?

Program the device via the ICSP pins after soldering, and remember to hold MCLR low during the programming sequence.
