HDK Specifications

1.5 HDK Specifications

• Board supply voltage: 5 V to 12 V DC

• Board supply current: 130 mA typ (fully active, CPU at 100 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 third party ARM IDEs. The IDEs

communicate with the board through the embedded emulator or an external JTAG emulator. To get

started, 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 TMS570LS04 family of MCUs have a large byte addressable address space. Table 1-1 shows the

address space of a TMS570LS0432 microcontroller on the left with specific details of how each region is

used on the right. On-chip Flash memory starts at the beginning of the address space where the exception

vector table is located.

0x0800 0000 0x0800 7FFF 32KB RAM

0x0840 0000 0x0840 7FFF RAM-ECC

1.8 Power Supply

The HDK board operates from either +5V supplied from the USB connector (J4) or +5 V to +12 V supplied

from the power supply connected to the main power input (P1), a 2.5 MM, barrel-type plug. Internally, the

power input is converted into +1.2 V, +3.3 V using Texas Instruments voltage regulators. The +1.2 V

supply is used for the MCU core while the +3.3 V supply is used for the MCU's I/O buffers and other

component on the board.

The power used for operation is determined by the options listed in Table 1-2.

There are multiple power test points on the HDK board. The three main test point pairs provide a

convenient mechanism to check the HDK’s current for each supply. Table 1-3 shows the voltages for each

test point and what the supply is used for.

2.2.1 20-Pin ARM JTAG Header

In addition to on board XDS100V2 JTAG. One 20-pin ARM JTAG header is added for using an external

emulator. This is the standard interface used by JTAG emulators to interface to ARM microcontrollers. The

pinout of the connector is shown in Table 2-2.

2.2.3 CAN Interface

The TMS570LS0432 has two DCAN interfaces which provide a high-speed serial interface. Two 3 pin

screw terminal blocks, J1 and J2, are used to interface with 12 the DCAN bus. The pinouts for this

connector are shown in Figure 2-3. H means CAN High (CAN H), and L means CAN Low (CAN L).

CAN Bus termination is used to minimize signal reflection on the bus. ISO-11898 requires that the CAN

bus have a nominal characteristic line impedance of 120 Ω. Therefore, the typical terminating resistor

value for each end of the bus is 120 Ω. A split termination method is used to help increase EMC

performance. Split termination is a concept that is growing in popularity because emission reduction can

be achieved very easily. Split termination is a modified standard termination in which the single 120 Ω

resistor on each end of the bus is split into two 60 Ωresistors, with a bypass capacitor tied between the

resistors and to ground. The two resistors should match as close as possible.
