Confused 40X2 pin count - labelling

[JPU]

Can someone please direct me as the Picaxe 40X2 DIL labelling in Picaxe manual 1 does not match the the 40X2 QFN pic available on Picaxe store which appears to have 44pins in total although we believe some are not connected?

Basically is there a reference available for the labelling of the Picaxe 40X2 QFN chip. (it has 44 PIN)

Thank you.

Note: Diptrace PCB layout for Picaxe 40 TQFN does reference 44 pins but the pin labels do not match the 40X2 DIL which is adding to my confusion.

Hi,

I would expect the details in the corresponding MIcrochip Data Sheet to be correct, all linked from here.

Cheers, Alan.

The TQFP is on page 40 of the manual https://picaxe.com/docs/picaxe_manual1.pdf
The QFN part is only available to special order, normally only used by industrial partners as it is so small. It does have a few different pins, the pinouts of all 3 parts are side by side within the Microchip datasheet in table 3.
