ELECTROSTATIC WARNING

The MSP430-5438STK 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 MSP430-JTAG, you will need LPT cable, if you use MSP430-JTAG-TINY or MSP-JTAG-ISO, you will need 1.8m A-B USB cable, if you use MSP430-JTAG-RF, you can connect it to the USB port of your computer, or via USB cable type A – female.

Hardware: Programmer/Debugger – one of our Programmers – MSP430-JTAG, MSP430-JTAG-TINY, MSP430-JTAG-ISO, or MSP430-JTAG-RF.

Software: MSP430 KickStart software.

BOARD LAYOUT

POWER SUPPLY CIRCUITMSP430-5438STK can take power from three sources:

– PWR connector where 9 V DC or 6 V AC is applied by external power source.

– +5V_USB from USB DEV

– JTAG, when P_IN jumper is closed. Note that the JTAG has current limitations.

The board power consumption is: about 20 mA with all peripherals and microcontroller running at full speed.

RESET CIRCUITMSP430-5438STK reset circuit includes JTAG connector pin 11, EXT1 pin 3, MSP430F5438 pin 96 and Reset button.

CLOCK CIRCUITQuartz crystal 32768 MHz is connected to MSP430F5438 pin 13(P7.0/XIN) and pin 14 (P7.1/XOUT).

Quartz crystal 18 MHz is connected to MSP430F5438 pin 89 (P5.2/XT2IN) and pin 90 (P5.3/XT2OUT).

JUMPER DESCRIPTIONPower In jumper:

P_IN jumper connects power supply from JTAG connector. You have to ensure that your circuit doesn't draw more than few milliampers current or the power supply may decrease due to the JTAG port current limitations. P_IN is useful and must be used mostly to program the microcontroller.

Power Out jumper:P_OUT jumper connects power from MSP430-5438STK to JTAG connector.

When this jumper cap is placed, the power supply of JTAG connector will follow the power supply of the board. This is useful when your board works at lower than +3,3V power supply.

Note:P_IN and P_OUT jumper caps should not be placed at the same time.

Input/Output

User joystick with name J1 – this is 4 directions plus center button, in the schematic the joystick four directions switches are connected: UP, DOWN, LEFT, RIGHT - through 33k resistors and CENTER through serial connected 330 and 33k resistors to 3.3V.

Status LED (green) with name LED1 connected to MSP430F5438 pin 83 (P10.7).

Status LED (yellow) with name LED2 connected to MSP430F5438 pin 82 (P10.6).

Power supply LED (red) with name PWR – indicates that external power source is applied and board power supply is applied.

Reset button with name RESET, connected to MSP430F5438 pin 96.
