Hi,

As you know that the USART module of LPC824 supports two modes, one is asynchronous mode, in the mode, the USARTx_SCLK signal  is NOT used. Another is synchronous mode, in the mode, the USARTx_SCLK signal is used.

In synchronous mode, the maximum USART rate is about 10MBP, which is described in data sheet of LPC82x.

In asynchronous mode, as you know that the maximum main_clock is is 30MHz, the maximum clock for U_PCLK is 30MHz*2 with FRG module, so the maximum bit rate of USART is:

bit rate is 30*2MHz/16=3.75M bit rate per second.

Hope it can help you
