"PIC16F18856-E/ML" is 28 pin or 40 pin?

[ocset]

Hello
We are looking to find the part number for the 28 pin QFN (6x6mm) version of the PIC16F18856 microcontroller.

Page 680 of the datasheet says that both 40 and 28 pin versions both have the "ML" suffix.

Surely this cant be right?

page 670 but yes, it's strange, as they usually use different suffixes for different pin variants of the same package in the same datasheet

in the table from page 3 you can clearly see that the '56 is the 28 pin variant. (by the number of IOs)

The part number is printed in the middle of each pinout diagram. You cannot miss it.

i don't know what you guys are thinking.

The suffix on Microchip micros has always described the type of package, nothing more.

Both of these devices come in an ML package. This basically means QFN. The 44 pin ML package is 8x8mm. The 28 pin ML package is 6x6mm.

/ML = QFN  (6x6mm up to 28 pin, 8x8mm for the 44 pin)
/MV = uQFN (4x4mm up to 28 pin, 5x5mm for the 44 pin)
/SO = SOIC
/SS = SSOP
/IL = DIP
/PT = QFP  (they seem to have stopped making new micros in QFP around 10 years ago, at least in the 8 bit families)

Some of these packages are not available in all pin counts. But all of the first 5 are typically available for both 28 and 40 pin micros.

Sometime you might see a "-T" after the suffix. This means the part comes on tape/reel. There are other suffix modifiers, but the package part "/XX" has been consistent for as long as I would know.
