just thought about building a motor driver with an STM32G431 and calling it... STDrive.

i'll see myself out.

@AgathaSorceress apparently you're not supposed to propose we guillotine the billionaires

what.

> NRAM is non-volatile memory utilizing a new technology called carbon nanotubes

heck,,

i think i'm gonna make a separate account "adventures of business catgirl" where i just infodump about projects and ideas that float in my head and nice chips i see and stuff.

now i just need to think of a handle and find an avi >.>

Zoé just invented a cocktail out of necessity tonight: the molyirtó. taste resembles a mojito but with none of the ingredients.

that took a bit longer to write, but i hope i condensed it nicely :D

be it internal presentations, more test reports or PCNs by other vendors which use the same process node.

With some effort one can then map out corporate structures, where what is made and how that changes over time, etc.

That's all, I hope ny'all had some fun :3

the tl;dr is: look out for specific codes which seem interesting and see where this leads you to.

Another fun part i randomly picked by browsing Mouser is STM32G431CBU6. This leads to... mouser.com/PCN/STMicroelectron
What's this? Capacity increase? Back in March already? Huh. So this has been going on for a while maybe.
*scroll* *scroll* *scroll* uwu, what's this? *notices presentation in the middle*
Page 24 gives us some more info as to where what was made and what the process codes are. This in turn can lead us to even more interesting information.

but naming can vary.

My second result leads to mouser.com/PCN/STMicroelectron distributors thankfully host PCNs for parts
as vendors mostly only give them to you if you're subscribed to changes.

reading this report gives us all kinds of interesting information, but the thing i want is on page 4:

TSMC 0.18µm, that's what we wanted to know. A few pages down it gets further detailed as "TSMC 0.18 Generic Embedded Flash logic TSMC" produced in Fab3 in Taiwan.

forecasting is a whole different thing though and bores me to death,
this is just about being curious and wanting to learn more about semiconductors.

Okay, let's start! i'm going with ST because of the current specific shortage and because i haven't looked at them before yet.

Let's go with the STM32F103 because it's just everywhere. let's search for "stm32f103 pcn" google.com/search?&q=stm32f103
we're more interested in the "process change" rather than "product change" type

Here's a thread on how to find out more about your IC.

I wanted to know more about a chip i was curious about and ended up finding out in which Fabs it was being manufactured
and in which process nodes. This can be useful if you want to compare parts from the same manufacturer (e.g. is just the design shit or is the node not that great)
or to see if you need to be scared about supply because of current events.

should i do a thread on google-dorking commodity ICs to find out where and with which internal process name a chip was made?

it's a fun OSINT exercise which isn't stalker-adjacent like "where and when was this picture taken"

also which manufacturer should i do? 👀

I really wish shipping costs would be lower within the EU, the 10-20 € flat fee per order makes lots of webshops very unattractive compared to amaz* or ali. :(
