Going forward, which MCU has Jeelabs settled on?

Added by NeverDie over 3 years ago

LPC810, LPC812, LPC824, or something else, or still undecided?

I’d like to get whatever MCU it is so I can follow along “hands on”, rather than just read along, with future Jeelabs posts. Which MCU should I get?

I think that LPC824 is a good general choice since it is generally a superset of the others with more flash, ram and an ADC.

OK, but what does jcw have to say? By all means express yourself, but since he’s running the show (or so I thought), in the end his answer is the only one that matters.

As you say but jcw is having a holiday from all this foolishness at the moment. I am sure he will share his view on his return. I just didn’t want you to feel lonely.

Oh, when’s he due back?
Yes, it is rather quiet here, so thanks for the company.

May I suggest the Atmel SAM L21? It consumes 35uA/Mhz, while in active mode, which appears to be much lower than ARM from its current competitors. It’s deep sleep is 200nA, which I would guess is “good enough.”

Interesting difference in the emulated EEprom endurance versus flash endurance on the L21, similar discrepancies on the D21.

I was hoping that @martyn would come in and cast some light on it since eeprom and flash appear to use the same area of the chip and yet have different cycle lifetimes.
