AM2431: General device and peripheral questions

Part Number: AM2431

Hello,

I have a customer evaluating the AM2431 for their application and we have the following questions:

  • Is there Brown-out detection built in?
  • How many DMA channels does this device have?
  • Can the FSI peripheral be configured as a UART?

Thanks!

  • Hey Matt,

    1) Yes, the AM243x contains Power-OK (POK) and Power-Good (PRG) peripherals capable of monitoring the various device voltage rails for Over/Under Voltage events. These events can trigger a device reset to ensure proper power-down sequencing. For additional details see the Device Configuration - Power chapter in the TRM.

    2) The AM243x uses the Data Movement Subsystem (DMSS) and designated Peripheral DMA's (PDMA). The DMSS consists of a Block Copy DMA (BCDMA) and Packet DMA (PKTDMA) each with there own set of DMA channels per core. The BCDMA has the following number of channels per core: 

    R5FSS0_0 = 6

    R5FSS0_1 = 2

    R5FSS1_0 = 4

    R5FSS1_1 = 2

    For additional details see the Data Movement Architecture chapter in the TRM.

    3) The FSI peripheral only supports a clock synchronous interface. It can support either FSI mode or SPI-compatibility mode. For additional details see the Peripherals - Industrial and Control Interface chapter in the TRM.

  • Thank you for the feedback Zack! 

    FYI the link to the TRM above is broken so I'm pasting the correct link here for reference: https://www.ti.com/lit/pdf/spruim2
