Yes, the tiny Freescale, Cypress, etc can be obtained for less than a dollar in a reasonable quantity [1]. The microcontroller market is changing pretty rapidly of late, with the number of products getting more and more broad. For your high reliability stuff, you'd probably want to look at the cortex-r series, which is built for the type of use cases you describe.

- nickpsecurity 11y agoAppreciate the confirmation. Outside embedded, one use for these people aren't appreciating is offloading interrupts or security checks of I/O devices. Along with sensors/mgmt stuff you can trust more. Cost being so low let's one do physical partitioning of domains instead of software. Also, thanks for the mention of Cortex-R as I hadn't heard of it. A quick glance at their description looks good. About $8 on low end to $50 on high-end. Getting quite cheap indeed for what 8-bits would be required for. Way cheaper than the old champ (RCA 1802 MCU) is today ($150 w/ 1k units). http://www.intersil.com/content/intersil/en/products/space-and-harsh-environment/harsh-environment/microprocessors-and-peripherals/CDP1802A.html?part=t&_charset_=UTF-8#overview http://www.intersil.com/content/intersil/en/products/space-a... Ok. So, I'll probably not have to go to 8-bit or drop large $$$ if I take-on certain projects. Good to know. Dirt cheap chips with large ecosystem, lock-step, real-time, and MPU's... it's like the golden era in tech for embedded start-ups, eh? :)
