PIC18F47K40-I PT TQFP44 Microcontroller

The PIC18F47K40-I PT TQFP44 is an 8-bit microcontroller supplied in a 44-pin TQFP package. It provides integrated Flash program memory and peripherals for embedded control tasks. Engineers select this device for new designs requiring a compact surface-mount form factor. The component is stocked as new inventory.

Suits firmware engineers building new boards

This part suits firmware engineers developing new printed circuit boards that specify the 44-pin TQFP footprint. It is not for technicians repairing legacy boards that use a different pin count or package style. Hobbyists without surface-mount soldering equipment should look at through-hole alternatives. Buyers needing a different memory density or peripheral set must choose another device.

44-pin TQFP package defines board layout

The 44-pin TQFP package fixes the PCB footprint and pin assignment for the design. Layout engineers must match this exact package to the board cad library. A different package variant will not fit the same land pattern. Confirm the package code before ordering to avoid assembly mismatches.

Questions about this item

How much power does the PIC18F47K40-I PT TQFP44 draw when running continuously?

The datasheet for this 18-pin microcontroller lists typical active current in the microampere range per MHz, so all-day operation adds minimal load to a regulated supply.

What external components are required to make this 44-pin TQFP device function?

A stable VDD supply, decoupling capacitors on each power pair, a pull-up resistor on MCLR, and an optional crystal or resonator for the oscillator.

Can this 47-series part share a 40 MHz bus with older 8-bit peripherals?

Its synchronous serial ports and parallel I/O support legacy timing, letting it interface with slower 5 V logic through level shifters.
