cheapest microcontroller
Hi,
I'm designing a 3.3V microcontroller based project that need to interact with two chips using UART and I2C. I would like to ask everyone what is the cheapest/smallest microcontroller to use? We plan to make tens of thousands of boards with the chosen microcontroller so I want to ask professional opinion before we decide what to use.
Basically the Microcontroller has to read data from the first chip using UART(3.3V, 19200bps), then write it to the second chip using I2C; The microcontroller then read the processed data from the second chip via I2C and write it to the first chip via UART. The microcontroller need to be the I2C master.
I see there are many 8-bit PIC microcontrollers from Microchip that have hardware based I2C & UART modules. But I heard PICs are not really used in a industrial setting and are used mostly by hobbyists.
I'd be really grateful if anyone can share suggestions on where do I start to decide the best microcontroller to use? it needs to be as small as possible, and due to the large number of PCB boards we will make, price is also a big concern.
Thanks in advance!!!
John.
