I am developing a card with msp430f249mpmep micro controller.
I use with UART protocol at a baud rate of 430.2Kbps and with internal ADC.
The micro controller will operate in a wide temperature range: -55 deg to 105 deg.
Is it possible to use the internal clock 16Mhz? or I have to connect an external clock at frequency 16MHz?
If I need to connect an external clock, you may recommend For an oscillator component?
