All this engineering work was done by Cypress for a device sold at a few dollars or so in quantity. Hardware wise most of these sig cap devices were reference designs clearly heavily using reference libraries. This isn’t bad, but the whole point of these relatively expensive (compared to say a bare 8051) devices (which is literal pennies) is to save all this R&D money. It also isn’t bad when someone takes this same off the shelf design and put it in a slightly shittier packaging and sell it closer to cost. This “infamous” line is silly as this microcontroller line existed nearly a decade before it became a thing in low-end/hobbyist sig cap devices. It originally was produced by a company called Anchor Chips in the late 90s and bought out by Cypress. It has been used in a lot of shit.
