Help me find the right microcontroller.
I a doing a project with 8051 series microcontroller and keil C51. I need help finding a micro with 2 hardware UART, 16 KB or 32 KB ROM and which works at 3.3V. I found this but it works at 5V (AT89C51RE2 ). Can I use this at 3.3V. I need to interface it witha device which works at 3.3V and I don't want to use voltage level translator. I have another question, does both UART have same interrupt priority? What happens if both UARTs receive data at the same time?
