I hear this argument a lot in the EE community. Yet, the cheapest 8051 part in single quantities on DigiKey: $0.43. Cheapest ARM Cortex-M0 part on DigiKey: $0.47. I'll take the ease of development and features on ARM for $0.05. You can develop without proprietary development environments. I do my development with a basic gcc+make setup.
Of course you can pick up old parts which fell off a truck for cheaper but I'd rather not do that when I depend on these parts for many years to come.
- janekm 8y agoThe cheaper 8051s aren't on digikey (they are usually integrated into something like the custom MCU used for a pregnancy test or tooth brush), and $0.05 is very worth it if you are making 1000000.
- vardump 8y ago8051 is a complete overkill for a pregnancy test or a toothbrush. That's why those applications use less known 4-bit processors.
