AM62A7: UART0, MCU_UART0, WKUP_UART0 Differences

Part Number: AM62A7

Hi,

In the AM62A there are 3 UART0

What is the difference between UART0, MCU_UART0, WKUP_UART0?

Can the 3 UARTS be for the user application or the 3 UARTS are for downloading and debug usage?

Hello Yaniv,

For your specific ask, I have a FAQ created about UARTs.

I would like you to go through the following: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1276094/faq-sk-am62-purpose-of-different-uarts

The most obvious is written below:

UART0: Main Domain UART, often abbreviated as SoC_UARTx in the schematics.

MCU_UART0: This is the MCU Domain UART.

WKUP_UART0: This is the wakeup domain UART.

Other differences would be in access latencies. The baud rate also plays a vital role here, this is mentioned in the datasheet and I have taken a snap of it:
