A new RPI Pico in the works?

Eben Upton Hints at an RP2040 Successor, Promises a Raspberry Pi Compute Module 5 in 2024

"We know what people don't like [and] what people do like," Upton says, "and we have a chip team."

I will call a spade a spade and say the sleep current of the RP2040 @ 1 mA is atrocious. I sincerely hope they improve the sleep current.

I think the QSPI memory controller could be improved as well.

Maybe more PIO memory...

But I don't have that many criticism about the pico.. 

Does the pico have any sore points for you?

  • The main reason that I don't use it at all is the lack of support in Keil MDK. Keil/ARM expect the micro supplier to make the necessary integration files but RPi have obviously not thought this worthwhile. I use the Keil tools all the time - so it really matters to me - others might not find it an issue at all.

    But there are other reasons too, lack of internal flash, odd peripherals -  the PIO is interesting but not very mainstream. The ADC is rudimentary (poor performance, only 4 channels). The timers are not  patch on what ST and others offer.

    The other big reason is that a lot of my work is designs that will be produced commercially  - and the RPI crew are not generally considered to be a serious chip supplier. That may not be fair (although I think it shows in the data sheet and support materials) but the hard fact is that they make only the one chip. I did look at ti quite hard (at RP2040) a couple of years ago but my customer preferred Giga Devices - although Chinese they look more like people seem to expect a chip supplier to look.
