I was looking into these recently. The current batch of the nRF54L15's was recalled, so I wonder when mass availability will happen. It looks like an interesting upgrade to the nRF52 though. The reason why I was looking at it is because I'm trying to hook up a 1kHz sampling ADC while streaming the data over BLE, and I need either a good DMA engine that can trigger on an external pin without a CPU interrupt, or a second core. I went down the dual core route, but I'd love to hear people's experience with DMA on the nRF52's and esp32-h2's and if it's finicky or not, and it's worth investing time into.

DMA will work fine. I remember a time when we were rewarded for making do with what we had rather than putting a handful of CPU cores on a sensor. These do not sound interesting to me, honestly. It sounds more like they can't figure out what they need to make.

  That was a time when gates were not as plentiful as they are now. Both the new Nordic SoCs are designed at 22nm. It can be a challenge as to what to use all the gates for.
