Hi Doing CPU vs ASIC switch, going from 300 uA to 3 uA can matter a lot when you are on a little battery
If you are going to put these in 10,000,000 watches / clocks a month, then saving twenty cents on a chip is a really big deal. Moving twenty cents a chip from your pocket to my pocket is enough to pay for a lot of development.. Yes, at that rate everybody in the country has a WWVB watch in three or so years. Cheap watch / clock lasts for a year or two …. How many watches and clocks are there around here…. Even at a couple million a year, the your pocket to my pocket math for the low power ASIC makes a lot of sense.
