HDK Specifications

• Board supply voltage: 5 V–12 V Vdc

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

1.5 Basic Operation

The HDK is designed to work with TI’s Code Composer Studio and other third party ARM IDEs. 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.

1.6 Memory Map

The TMS570LC43 family of MCUs have a large byte addressable address space. Table 1-1 shows the address space of a TMS570LC4357 microcontroller on the left with specific details of how each region is used by the HDK 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. CS[4:2] are used for synchronous memory for example SRAM, NOR Flash, NAND Flash, and so forth.

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.

1.7 Power Supply

The HDK board operates from a single +12 V external power supply connected to the main power input (P1), a 2.5 mm, barrel-type plug. Internally, the +12 V input is converted into +1.2 V, +3.3 V and +5.0 V using Texas Instruments swift voltage regulators and PTH power module. 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 module on the board. The +5.0 V supply is used for ADC power (second option) and USB VBUS.

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 1-2 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 external emulator. This is the standard interface used by JTAG emulators to interface to ARM microcontrollers. The pinout for the connector is shown in Table 2-2.

2.2.2 Ethernet Interface

The TMS570LC4357 integrates an MII/RMII Ethernet MAC on chip. This interface is routed to the on board PHY via CBT switches. The board uses a DP83640 PHY. The interface is isolated and brought out to a RJ-45 connector with integrated magnetics, J1. The pinmux control DIP S2 is used to control the CBT FET switch for RMII, MII or other functions.

The J1 connector is used to provide a 10/100 Mbps Ethernet interface. This is a standard RJ-45 connector. The cable end pinout for the J1 connector is shown in Table 2-3.

www.ti.com

Table 2-2. 20-Pin ARM JTAG Header

Two LEDs are embedded into the connector to report link status (green LED) and transmit and receive status of the PHY (yellow LED).

2.2.3 CAN Interface

The TMS570LC4357 has up to three DCAN interfaces that provide a high-speed serial interface. Two 3pin 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).

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 Ω resistors, with a bypass capacitor tied between the resistors and to ground. The two resistors should match as close as possible.

2.2.5 J7, XDS100V2 USB JTAG Interface

The USB connector J7 is used to connect to the host development system that is running the software development IDE, Code Composer Studio. The signals on this connector are shown in Table 2-6.

Table 2-6. J7, XDS100V2 USB JTAG Interface

Pin Number Signal Name

1 USBVDD 2 D3 D+ 4 NC 5 USBVSS

Before the board is shipped, the XDS100V2 port1 is configured as JTAG, and port2 is configured as SCI. The CPLD on the board is also programmed to route the JTAG signals to the MCU.

There is a circuitry to detect the external JTAG emulator. If a device is plugged onto the header J4 and J19, the DS1 LED will be turned on, and XDS100V2 JTAG is disabled.

2.2.6 P1, +5 V to +12 V Input

Connector P1 is the input power connector. This connector brings in +5 V to +12 V to the HDK board. This is a 2.5 mm jack. Figure 2-6 shows this connector as viewed from the card edge.

www.ti.com

2.2.7 SCI Interface

The internal SCI on the TMS570LC4357 device is connected to the second port of the XDS100V2. The XDS100V2 USB driver makes the FT2232H second channel appear as a virtual COM port (VCP). This allows the user to communicate with the USB interface via a standard PC serial emulation port.

2.2.8 Daughter Card Interface

The HDK provides expansion connectors that can be used to accept plug-in daughter cards. The daughter card allows users to build on their EVM platform to extend its capabilities and provide customer and application specific I/O. The expansion connectors are for all major interfaces including asynchronous memory, peripherals, and A/D expansion.

There are three daughter card interfaces: J9, J10, J11. These connectors are described in Table 2-7.

2.3 LEDs

The TMS570LC43 HDK board has 19 LEDs. Eight of these LEDs (shown in Table 2-10) are under user control. Those LEDs are controlled and programmed by NHET signals.

LEDs DS2, DS3, DS4, and DS5 indicate the presence of the power (+1.2 V, +5 V, 3.3 V, and 12 V) s on the board. The LED functions are summarized in Table 2-10 and Table 2-11.

The S2 DIP switch is reserved for user application general purpose. Table 2-12 describes the function of each channel on S2.

(1)

S2:1 indicates slide 1 on the S2 DIP switch, S2:2 indicates slide 2 on the S2 DIP switch, and so on.

(2)

S2:2 and S2:3 cannot be enabled at the same time since those two ports have pinmux.

(3)

To use Ethernet, S2:4 should be enabled and all other have to be disabled.

2.5 Jumpers

The HDK board has two jumpers that are used to enable and disable the on-board SDRAM and select 5 V or 3.3 V ADC.

2.6 S4, Power On Reset Switch

TMS570LC43 MCU has two resets: warm reset (nRST) and power-on reset (nPORRST). Switch S4 is a momentary switch that asserts power on reset to the TMS570LC4357 device. The nPORRST condition is intended to reset all logic on the device including the test and emulation circuitry.

2.7 S3, System Reset Switch

Switch S3 is used to assert a warm reset the TMS570LC4357 device. Warm reset does not reset any test or emulation logic. The reset signal from window watchdog will also assert a warm reset to the MCU. The warm reset can be invoked by pushing nRST button, or by RESET signals from XDS100 CPLD, ARM JTAG SREST.
