TMS570LS EVAL BRD

About This Manual

This document describes the board level operations of the TMS570LS31 Hercules™ Development Kit (HDK). The HDK is based on the Texas Instruments TMS570LS3137 Microcontroller. The TMS570LS31 HDK is a table top card that allows engineers and software developers to evaluate certain characteristics of the TMS570LS3137 microcontroller to determine if the microcontroller meets the designer’s application requirements as well as begin early application development. Evaluators can create software to execute on board or expand the system in a variety of ways.

Notational Conventions

2.1 Board Layout

The TMS570LS31 HDK board is a 4.9 x 4.3 inch (125 x 109 mm) eight layer printed circuit board that is powered by an external +5 V to approximately +12 V only power supply. Figure 2-1 shows the layout of the TMS570LS31 HDK board.

2.2 Connectors

The HDK board has 13 interfaces to various peripherals. These interfaces are described in the following sections.

2.3 CAN Interface

The TMS570LS3137 has up to three DCAN interfaces that provide a high-speed serial interface. Two 3- pin screw terminal blocks, J2, J3, are used to interface to the DCAN bus. The pinouts for this connector are shown in Figure 2-4. H means CAN High (CAN H), and L means CAN Low (CAN L).
