The big thing is not this phone, it's the chip.
The chip(MT6250) is a processor for feature phones which includes 260 mhz arm7 cpu,8Mbyte
of ram , dsp,bluetooth,2.5G and All kinds of IO. It can run games on a touchscreen phone.
And it costs $2 in large volumes. This is much less than many microcontrollers who offer much less capability. And with such performance and memory , it can support much better languages and tools, faster time to market, and more complex systems, for cheap.
Also , this chip uses 2 different silicon pieces(one for processor and one for ram), for very low cost, instead of what we do today: build different stuff on the same silicon piece and compromise performance and cost and development time along the way. This could open the way to a lot of innovation.
- michaelt 13y agoIt's not at all unusual to see separate CPU, RAM and flash memory in products like routers. The thing is the interfaces between CPU, RAM and flash tend to use a lot of pins - especially if you want them fast and with support for lots of memory. Look at the number of contacts you get on a stick of RAM in a PC. Lots of pins is acceptable in a product like this which is BGA surface mounted - but for things like Arduino where the pins are 0.1" apart for easy manual working, having the memory and flash on-chip is much more practical :)
