00:29 <whitequark> thought: it's good we don't have an onboard STM32 to manage misc functions and it's all on the FX2

00:29 <whitequark> or we'd be in an even worse situation

00:31 <ebb> an onboard rp2040 on the other hand

00:31 <ebb> (not that anyone should mistake that for a suggestion...)

00:32 <whitequark> heh

00:32 <whitequark> we could put another 8051 on there!

00:32 <whitequark> i don't think we're gonig to have a shortage of those

00:33 <whitequark> i should finish my 8051 softcore

00:34 <d1b2> <Darius> surely there is another 8051 core buried in it somewhere

00:34 <whitequark> w-where?

00:35 <d1b2> <Darius> I dunno but they seem to be everywhere

00:36 <whitequark> i mean yeah

00:43 <d1b2> <brainstorm> sh4 j-core softcore instead of 8051 because why not 😛 ... interesting conversations with the j-core folks in private, btw, I'm reaching out to Renesas folks and see what's their 2021 posture on H-UDI specs releasing... not holding much hope, but worth a shot, imho.

00:50 <icb> Don't you already have the one required 8051 per project in the FX2?

00:50 <whitequark> (one that _we know of_!)

00:51 <whitequark> but yes. the reason to have an STM32 around would be to have more pins / functions

00:51 <whitequark> since the FX2 is IO limited and we bumped into that a few times

00:54 <ebb> bet that TI part has a 8051 for signal processing or something dumb

00:54 <whitequark> which part? we have a lot!

00:54 <ebb> Oh, fair point :') the one that's particularly holding up the production run

00:55 <ebb> But I'm (hopefully) fully joking

00:55 <ebb> TPS73101

00:56 <whitequark> yeah no that one isn't going to have a core in it

00:56 <icb> Linear regulator: probably no 8051. Switching regulator: Probably 8051

01:05 <d1b2> <Darius> you know it's true

01:05 <d1b2> <Darius> the world is not kind enough for it to be wrong

01:12 <icb> 8051s are the cause of, and solution to, all of life's problems

01:15 <davidc__> icb: technically, the C8051F54x is an LDO with integrated 8051

01:16 <davidc__> (though the vendor has chosen to call it an 8051 with integrated LDO, as they lack imagination)

01:19 <d1b2> <Darius> 50MHz* (has internal 2x48MHz clock)

01:28 <davidc__> I know edsen has been running down all possible sources for the TPS73101 - arrow claims to have 2500 in stock. I guess its probably phantom stock?

01:31 <davidc__> (actually, has a slightly different suffix, so might not be the part you need. But if it is: https://www.arrow.com/en/products/tps73101mdbvrep/texas-instruments )

03:07 <d1b2> <esden> @davidc__ ... yeah for $2.51 a piece ... for a ~$0.40 part... we only raised so much money we can't just buy any scalper price part unfortunately 😦

03:08 <d1b2> <esden> sorry $2.14...

03:08 <d1b2> <esden> what the ... lol

03:08 <d1b2> <esden> (I did not intend to send the strange bird 😄

03:09 <d1b2> <esden> but I am indeed sorry 😦

03:09 <esden> ohh interesting it does not show on the IRC side of things

03:12 <d1b2> <esden> in any case.. we do keep searching and finding tiny pockets of more or less reasonably priced TPS73101 that we buy at every opportunity ... when there is enough of them and we sort out all the logistics of sending the parts to china for assembly we will do that. We will get there eventually. 🙂

03:43 <davidc__> esden - ah fair enough. I had no idea what the original pricing was on that, so didn't realize how unrealistic it is

03:49 <davidc__> Good luck with the continued hunt, and I'll let you know if I see any more - assuming they are priced realistically!

05:58 <d1b2> <esden> @davidc__ thank you! doing our best. 🙂

06:09 <davidc__> esden: you've done parts import to china before? (I'm sure thats figured out - but if its not, I thought I might provide a warning)
