I'm a bit surprised they have two MCUs though (BCM5976 and STM32)

- p_l 4y agothe BCM5976 is dedicated touchscreen ASIC that Broadcom makes for Apple for their iPhone and iPad devices, there's probably MCU (or four, this is broadcom we're talking about) inside, but that's probably because it's simpler to implement this way.
- magicalhippo 4y agoReminded me of the Raspberry Pi Pico W[1], where they paired a dual-core ARM Cortex M0+ MCU with a wifi chip that has both a Cortex M3 core and a Cortex M4 core[2]. The Arduino Unos being paired with an ESP-01 module is similar. Tons of other examples out there as well of course. Not sure if there's a similar "power inversion" at play here, just find it funny when it shows up.
