2 INTRODUCTION: MSP0-HG is header board with MSP0GIPWR ultralowpower mixed signal microcontroller from Texas Instruments. MSP0GIPWR has a built-in -bit timer, ten I/O pins, a 0-bit A/D converter and built-in communication capability using synchronous protocols (SPI or IC). On the board are available JTAG connector, one status led and extension headers for each microcontroller pin, where you can connect your own circuits. All this allows you to build a diversity of applications. BOARD FEATURES: Microcontroller MSP0GIPWR JTAG interface Status led Extension headers for each microcontroller pin FR-,. mm, soldermask, component print Dimensions:.00 x 0.00 mm (.0 x 0.9") ELECTROSTATIC WARNING: The MSP0-HG board is shipped in protective anti-static packaging. The board must not be subject to high electrostatic potentials. General practice for working with static sensitive devices should be applied when working with this board. BOARD USE REQUIREMENTS: Cables: The cable you will need depends on the programmer/debugger you use. If you use MSP0-JTAG-TINY, MSP0-JTAG-TINY-V or MSP0JTAG-ISO, you will need USB A-B cable. If you use MSP0-JTAG, you will need LPT cable. Hardware: Programmer/Debugger MSP0-JTAG, MSP0-JTAG-TINY, MSP0-JTAG-TINY-V, MSP0-JTAG-ISO by OLIMEX, or other compatible programming/debugging tool.

6 BOARD LAYOUT: POWER SUPPLY CIRCUIT: MSP0-HG can take power form: EXT pin (VIN) and pin (GND) from to VDC not typical POWER connector (the connector looks like opened jumper) from to VDC JTAG The programmed board power consumption is about 0 ma with all peripherals enabled. RESET CIRCUIT: MSP0-HG reset circuit includes MSP0GIPWR pin 0 (RST/NMI/SBWTDIO), JTAG connector pin, and R (kω). CLOCK CIRCUIT: Quartz crystal. khz is connected to MSP0GIPWR pin (XOUT/P.) and pin (XIN/P./TA0.). Page

7 JUMPER DESCRIPTION: P_IN P_OUT When this jumper is closed, the board is power supplied by the standard JTAG pin. This is only possible when the consumption of the board is not very high which is typically the case with MSP0 microcontrollers. If this jumper is open the board should be power supplied by another external source. This jumper and P_OUT should always be reversely open/closed, i.e. if P_IN is closed, P_OUT should be open and vice versa. Default state is closed. When this jumper is closed, the board is power supplied not by the JTAG but from external source. Then the JTAG has to synchronize with the working voltages which is done through this line. This is especially important when debugging with JTAG. This jumper and P_IN should always be reversely open/closed, i.e. if P_OUT is closed, P_IN should be open and vice versa. Default state is opened. INPUT/OUTPUT: Status led (red) with name LED, connected to MSP0GIPWR pin (P.0/TA0CLK/ACLK). Page
