XC2000Easy Kit

Introduction


1 Introduction

The XC2000 is a new family of 16/32-bit microcontrollers based on the high-performance C166S V2 core. The C166S V2 core more than doubles the performance of the well established C166 core while still providing code compatibility.Applications can be developed easily. The Evaluation Board is equipped with peripherals for connection to the environment. An On Board Wiggler allows easy access to all peripherals and the core. For programming of the embedded Flash, MEMTOOL is available. The Evaluation Board allows the easy development of XC2000 family applications with the corresponding tools. Subsequently, the applications can be downloaded and can be tested with the several powerful debuggers. For detailed technical information about the different derivatives please refer to the XC2000 family web pages on the Infineon Internet.

2.4 DIP Switch S102Although most of the programmable features of the XC2000 are selected by software either during the initialization phase or repeatedly during program execution, some features must be selected earlier because they are used for the first access of the program execution.These configurations are accomplished by latching the logic levels at a number of pins at the end of the internal reset sequence.DIP switch S102 allows to configure the startup setting of the XC2000 during RESET. The default System Startup Configuration is shown in Table 1. By default all DIP Switches are OFF. The XC2000 executes a standard start from internal Flash.

Table 1 Default configuration

Table 2 Basic Startup Configuration via External Circuitry

For more detailed information about the DIP switch setting please refer to Chapter 3.1, Table 4.

2.5 Easy Kit Power Supply conceptThe Easy Kit USB Power Supply concept enables the user to work with the Kit without an external Power Supply. If the USB power supply is not sufficient an additional regulated DC power supply can be used.

Figure 3 Easy Kit Power Supply concept

By means of the Power Supply Jumper X502, USB, or the external power Supply can be selected to run the Easy Kit. The Setup for the Jumper X502 is shown in Table 3 below.

The USB specification provides a 5 V supply on a single wire from which connected USB devices may draw power. The specification provides for no more than 5.25 V and no less than 4.35 V between the +ve and -ve bus power lines.Initially, a device is only allowed to draw 100 mA. It may request more current from the upstream device in units of 100 mA up to a maximum of 500 mA. In practice, most ports will deliver the full 500 mA or more before shutting down power, even if the device hasn't requested it or even identified itself. If a (compliant) device requires more power than is available, then it cannot operate until the user changes the network (either by rearranging USB connections or by adding external power) to supply the required power.

Note: If the USB power supply is not sufficient, an external power supply is needed and the Jumper X502 setting need to be changed.

Note: In case the USB Host PC goes into Suspend Mode, an external Power Supply should be used.

2.5.1 Power Supply via Power PlugThe XC2000 Board can be supplied either with USB cable or with an external power supply. For external power supply a regulated DC power supply with max. 12Volt/ 400mA can be connected to the power connector. The maximum power dissipation of the used voltage regulator has to be taken into account.

Description of Connectors and Switches


3 Description of Connectors and SwitchesThe On-Chip Bootstrap Loader allows the start code to be moved into the internal PSRAM of the XC2000 via the serial interface ASC0. The microcontroller will then execute the loaded start code out of the PSRAM.

3.1 Switch S102

Note: For debugging purpose (OCDS) the standard start from internal Flash configuration must be used.

Memory Models


4 Memory Models The memory space of the XC2000 is configured in a “Von Neumann” architecture. This means that code and data are accessed within the same linear address space. Attached there are two examples for memory mapping of the XC2000 Board.

4.1 Internal FlashAs a example the XC2287-96F66L incorporates 768 Kbytes of embedded Flash memory (starting at location C0’0000H) for code or constant data. It is operated from the 5Volt pad supply and requires no additional programming voltage. The Flash memory consists of three independent flash modules. Each module is 256 Kbyte wide. Each Flash array is organized in 64 physical sectors of 4 Kbytes. It combines the advantages of very fast read accesses with protected but simple writing algorithms for programming and erasing. The 128-bit code read accesses from the Flash memory realize maximum CPU performance by fetching two double word instructions (or four single word instructions) in a single access cycle.Data integrity is enhanced by an error correction code enabling dynamic correction of single bit errors. Additionally, special margin checks are provided to detect and correct problematic bits before they lead to actual malfunctions.The On-chip programming can be done either with a utility program, so called “Memtool” or with several other Toolchains from our Tool vendors. Memtool is using the ASC bootstrap Loader. The latest version can be found on the Infineon website. Other tools use the OCDS interface.

Figure 10 Example for memory mapping (internal flash)

Memory Models


4.2 Internal PRAMAs a example the XC2287-96F66L provides 64 Kbytes of PSRAM (E0’0000H … E0’FFFFH). The PSRAM provides fast code execution without initial delays. Therefore, it supports non-sequential code execution, for example via the interrupt vector table.

Getting Started


5 Getting StartedFor the successful start up of the XC2000 Easy Kit, the following items should be done:

Figure 12 XC2000 Easy Kit (144-Pin)

By default a HELLO WORLD program can be executed. The following steps are needed to be successful. 1. Verify that the Jumper JP201 is in position 1-2 (powered via USB).2. Connect USB cable with starterkit and PC.3. Install DAS driver from starterkit CD.4. Verify if the standard start mode is selected as described in chapter 3.1.5. LED D105 connected with P10.0 should flash, otherwise press the Reset button.6. Verify which COM port is activated for the FTDI - chip.7. Execute the monitor program MTTTY from the starterkit CD.8. Select the corresponding COM port, 19200 Baud, none parity, 8 data Bit, one stop bit,

parser off.9. Start connection (File/connect).10.Press Reset button on the starterkit, Hello World program is running .

5.1 Power SupplyIf more current is needed, a regulated DC power supply with max. 12 Volts should be connected to the power connector. The maximum power dissipation of the used voltage regulator has to be taken into account. By default one green LED should be active. It indicates that the embedded voltage regulator supply the microcontroller.Please Note, the power supply is not part of the delivery !

5.2 OCDS Debugging InterfaceThe XC2000 Easy Kit offers two types of JTAG interfaces. With the FTDI chip an on board USB JTAG wiggler has been implemented. Further the USB interface allows to emulate a USB to UART bridge. Both can be done at the same time.A simple 16 pin JTAG header can be used to connect a debugger from one of Infineon’s tool suppliers. Both systems include an On-Chip Debug Support (OCDS) system, which provides convenient debugging, controlled directly by an external device via debug interface pins.

5.3 USB Interface for UART supportFor flashing the program to the microcontroller a USB interface among the PC and the XC2000 board is needed. The on board FTDI device converts the USB protocol the ASC protocol.

Figure 15 USB Interface on the XC2000 board

5.4 MemToolMemtool is one of Infineon’s solutions for programming code and data into FLASH Memory. Memtool supports on-chip FLASH Memory as well as dedicated Flash chips on the target board.

5.5 ASC Bootstrap To establish the connection between the ASC bootstrap loader of the XC2000 microcontroller and the PC (MemTool) the bootstrap loader mode has to be configured.

5.7 Connect to the TargetMake sure that the Starter Kit board is connected to your PC as well as to your power supply. Hit the reset key on the starter kit. Now press the 'connect' button in Memtool.If the software status bar displays 'Ready for Memtool Command', you have successfully installed Memtool.
