Using two LPC4357 I would like to establish a DMA based USART connection between them for high speed data transfer. This means data transfer should be as fast as possible. Unfortunately there is no clear statement in the datasheet or user manual about the maximum baudrate.

The only information I found is the typical USART clock cycle time of 0.1 µs. This would mean, that the maximum speed is 10,000,000 Bits/s.
Using "no parity" and "one stopbit", the transfer of one byte needs 10 Bits. Thus the maximum speed equals 1,000,000 Bytes/s.


Can anyone from NXP confirm this?


Best regards,
Holger
