TMS320F2806: UART communication speed

Liu Yang

Part Number: TMS320F2806

Hi Team,

Please help me answer the follow question, thank you so much.

For some microcontroller for example tms320f2806, where can I confirm the speeds of UART communication?
Is there any device that supports 11.25Mbps?

Tom,

Please see the F2806 datasheet sprs230o, section 6.2.8.

Max bit rate is LSPCLK/16 for the SCI.

So, for 100 MHz devices, 100 MHz/16 = 6.25 Mbps.

For 60 MHz devices, 60 MHz/16 = 3.75 Mbps.

Regards,

David

Hi David,

Thank you for your answer.

If I want to a microcontroller that supports 11.25Mbps, the LSPCLK should be 16*11.25=180Mbps, am I right?
Is there any device that fulfill the requirements below?

[CAN communication]
Number of CH: 1 Ch or more
Protocol: Standard CAN protocol
Communication speed: 1Mbps

[UART communication]
UART communication speeds: 11.25 Mbps.
Number of CH: 2 Ch or more
Synchronous system: Asynchronous
Communication speed: 11.25Mbps
Data length: 8bit

Tom,

Please see the TMS320F2837xS and TMS320F2837xD devices:

(You can also see the TMS320F2838xS and TMS320F2838xD devices too, but they are more expensive).
