Block Diagram

1 Block Diagram

Section 1 shows a high-level block diagram of the superset TMS570LS31x microcontroller. For the actual

block diagram relevant for any derivative of the TMS570LS series or for the RM4x series of

microcontrollers, see the device-specific data sheet.

Figure 1. Device Block Diagram

The block diagram includes a color-coded representation of the individual core-power domains

implemented on the microcontroller (see Figure 2). These power domains can be individually turned ON or

OFF during initialization as per the application requirements.
