Give me a microcontroller with between 32K and 2MB of onboard flash, some eeprom, multiple CAN peripherals, ADC, SPI, good timers, and some specialized peripherals - synched PWMs with dead time for driving power electronics, and some other special things. Dual-core lockstep for safety critical things (like the fronk latch). Some combination of all that at a price starting under a dollar.
Oh, and a temperature range of -40 to +125C ambient.
Can Intel do that on their obsolete 16nm multipatterning process for anywhere near the price target? Didnt think so.
- YetAnotherNick 5y agoESP32 satisfies each of your requirement. They are available for $1(without BT sensor) in bulk pricing, have 4MB flash, have eeprom, have CAN, ADC, SPI, goof timers, good PWM, good DAC, is realtime, dualcore, and ambient temperature range of -40 to +125 C.
