After i have done lot of searches i found this one MK30DX256VLH7-ND from NXP kinetis. but i need with lower price
My application is tracking system with OBD,This system will have gsm,gps,interface
What about LPC11x6x family from NXP? I am using a really small development board with NXP LPC11U68 Cortex-M0+ from this site ([url]https://eigerdb.eu/)[/URL] where I also found some interesting basic tutorials. That is why I am using it. I think that the micro-controller has all peripherals that you need.
