MSP430-5438STK development board Users Manual All boards produced by Olimex are ROHS compliant Rev.
INTRODUCTION MSP430-5438STK development board provides easy way for developing and prototyping with MSP430F5438 mixed signal microcontroller produced by Texas Instruments. This powerful microcontroller supports various serial interfaces such as USB Device, UART, SPI. In addition you will find also audio input and output, debug interface, LCD, UEXT, two Extensions, mini SD/MMC, User Joystick, User Leds, Reset button.
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.

BOARD LAYOUT POWER SUPPLY CIRCUIT MSP430-5438STK 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 CIRCUIT MSP430-5438STK reset circuit includes JTAG connector pin 11, EXT1 pin 3, MSP430F5438 pin 96 and Reset button.
JUMPER DESCRIPTION Power 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.
