1.5 HDK Specifications

 Board supply voltage: 5V–12V Vdc

 Board supply current: 130mA typ (fully active, CPU at 180 MHz)

 Dimensions: 4.90” x 4.30” x 0.85” (LxWxH)

1.6 Basic Operation

The HDK is designed to work with TI’s Code Composer Studio and other 3

ARM IDEs (Integrated Development Environments). The IDE communicates with

the board through the embedded emulator or an external JTAG emulator. To

start, follow the instructions in the Quick Start Guide to install Hercules specific

software. This process will install all of the necessary development tools,

documentation and drivers.

1.7 Memory Map

The TMS570LS31 family of MCUs have a large byte addressable address space.

The memory map table shows the address space of a TMS570LS3137

microcontroller on the left with specific details of how each region is used on the

right. By default, the internal memory sits at the beginning of the address space.

The SDRAM is mapped into CS0 space on the EMIF. CS2/3/4 are used for

synchronous memory for example SRAM, NOR flash, NAND flash etc.

To use EMIF, the MPU has to be enabled, and the CS regions have to be

configured as “device mode” or “strongly ordered mode” through MPU.

1.8 Power Supply

The HDK board operates from a single +12V external power supply connected to

the main power input (P1), a 2.5 MM, barrel-type plug. Internally, the +12V input

is converted into +1.2V, +3.3V and +5.0V using Texas Instruments swift voltage

regulators and PTH power module. The +1.2V supply is used for the MCU core
