AMD's Geode LX SoC won't ship its last order until this year, 2019. The Geode line predates the C3, and the Geode LX is just as old as the C3. I can't confirm when the C3 stopped shipping, but it was probably this decade.
As for microcode vulnerabilities, don't be surprised if they start coming down the pipeline. It was only recently that researchers figured out (publicly, at least) how to hack and upload microcode on Intel chips: https://media.ccc.de/v/34c3-9058-everything_you_want_to_know_about_x86_microcode_but_might_have_been_afraid_to_ask https://media.ccc.de/v/34c3-9058-everything_you_want_to_know...

[0] > This alternate instruction set includes an extended set of integer, MMX, floating-point, and 3DNow! instructions along with additional registers and some more powerful instruction forms over the x86 instruction architecture. > This alternate instruction set is intended for testing, debug, and special application usage. Accordingly, it is not documented for general usage. If you have a justified need for access to these instructions, contact your VIA representative. It then goes on to explain in detail the mechanism for initiating execution of this alternate set of instructions. So while I am sure the researchers put plenty of work in this it seems reading the manual helped a lot more than one would expect for a "backdoor"...
