Microcontroller for embedded control

The PIC16F1786-E ML QFN28 is a new 8-bit microcontroller supplied in a 28-pin QFN package. It targets engineers developing space-constrained embedded applications that require integrated peripherals and low-power operation. The device suits production designs where board area is at a premium.

Suits compact designs; not for high pin-count needs

This part fits projects that can work within a 28-pin footprint and do not require external memory interfaces. Developers needing more I/O lines, larger program memory, or higher-speed communication blocks should evaluate devices with greater pin counts and expanded peripheral sets.

28-pin QFN package defines board integration

The 28-lead QFN package fixes the physical layout and available I/O count for the design. Verifying that the pin-out matches the schematic and that the thermal pad layout meets the assembly process is the decisive step before committing to this device.

Questions about this item

How is the QFN28 package soldered to the board and what step is often missed?

The 28-pad QFN package requires reflow soldering; the exposed thermal pad on the underside must be soldered to the PCB ground plane or the device will not make reliable electrical contact.

What maintenance or replacement will the PIC16F1786-E need during its service life?

The microcontroller itself has no user-serviceable parts; replacement is only necessary if the device suffers electrical overstress or physical damage during board assembly or operation.

What limit appears first when the device runs continuously at maximum clock rate?

The internal temperature rise from sustained switching current becomes the limiting factor; adequate PCB copper area under the thermal pad is required to keep the junction within its rated operating range.
