Hello all,
I am looking for a low cost micro with 4 UARTS. The requirments are quite staringhtforward since none of the ports will be going that quickly (4800 baud to 19200 baud) and only a few hundred bytes per second on 3 of the 4 ports (with the last port mostly idle).
I'll also need some simple I/O (about 6 I/O lines should be OK) plus an I2C or similar (but that could be bit-banged since there won't be much data to pass on this bus).
Ideally I'd like FLASH and RAM on chip.
The target volume for this product would be a few thousand per year.
I know of rabbit and it looks like the latest ATMega2560 would be OK but are there any others?
Thanks
Iain
