LQFP32 & LQFP44 IPC land patterns needed
Circlotron:
Looked and looked for these. Could someone post up a diagram please? Is QFP the same footprint as LQPF?
T3sl4co1l:
They're not in the datasheet?
What EDA?

Circlotron:
Not that I can see.

I used to have an IPC land pattern book but I've lost it.
Siwastaja:
That's a reference manual. It's for a system designer and programmer. You need the datasheet. It's necessary for electrical design, including schematics and layout.
First result in Google:
https://www.nxp.com/docs/en/data-sheet/MC9S08PA16_Rev.1.pdf
Though, unlike typical, they haven't copy-pasted the package drawings, but give you references to the document numbers you need, on page 29:
98ASH70029A and 98ASS23225W
Circlotron:
Okay, thanks. No wonder I couldn’t find it! I do in fact have that data sheet though.
Edit -> had a look at that reference... it only has info on the package appearance and dimensions. No info on the pcb pad sizes and location. :-( Back to square 1.
