For that price I'd believe you can get only those without packaging

I think you can get 8051 parts for that.

  Yea I'm hoping somebody can provide a list of various manufacturers and part names similar to the article..

    My article includes the Holtek HT-66, the STCmicro STC8, the Nuvoton N76, and the ST STM8 — all hover in the 1-2 RMB range (especially when purchased in volume from within the mainland). The STC8 and N76 parts are 8051, the other two are their own design. The HT-66 looks very much like a PIC16 part, and IDE and compiler are totally free. The STM8 is probably the best-performing part in that price range, and has a free IDE and compiler. My review includes pretty extensive discussion on the main page, plus separate reviews for all these parts — check it out and let me know if I need to clarify anything!

      This is a great blog post but I'd also like to throw in that the STM line has a pretty great linux toolchain (official or not, I'm not sure). I made a repository for the toolchain necessary to get STM boards working here: https://github.com/abraithwaite/STM32 https://github.com/abraithwaite/STM32 Although it's outdated, the links at the bottom appear to link to updated tools which are presumably better :-)

      Yeah, the STM8S003 is pretty hard to beat around $0.25, with excelent code-density, free IAR development and a very assembly-friendly architecture.

I will be Shenzhen in a few weeks. Will try to buy something for 1¥ :)

There's a popular CPU in China meet your requirement: http://stcmcu.com/ http://stcmcu.com/ but in Chinese

  Any website where I can order a few for testing?

Recently I was looking for a project that required a network of microcontroler and was looking for the cheapest mcu in around quantity 50. My requirements where pretty modest, I just needed 2 GPIO and 1 PWM ouput. I ended up ordering the Attiny13A as that was the cheapest option in aliexpress/ebay with freeshipping in small quantities (around USD $0.3 a piece). I would have loved to find something even cheaper!
