Do these have cost savings over a budget-series 32-bit MCU, eg using Cortex-M0? For example, STM32G0 is very cheap (~$1-4 USD depending on variant and quantity)

Do these have cost savings over a budget-series 32-bit MCU, eg using Cortex-M0? For example, STM32G0 is very cheap (~$1-4 USD depending on variant and quantity), and has a number of peripherals.
My guess: 8-bit MCUs are used for high-production run, minimal cost uses where the MCU does one specific task, probably in a network with other MCUs. In these cases, they could offer cost savings, even over an M0/M0+.
- iasay 4y agoYes. You can get an 8-bit for $0.15 in quantity and they go down to 6-pin SOT-23 or even smaller parts. The PIC10F320 is an interesting one as it can replace a fairly large amount of discrete logic very easily. I think I paid $0.47 in one off quantity for those! It was used to entirely replace a couple of timers and a state machine.
