ler by Texas Instruments. This ultra-low-power microcontroller has integrated
CC1101 RF transcei er. The board has also UEXT, which can be modified as de ice
or host. MSP430-CCRF can communicate with other boards with integrated
CC1101 RF transcei er ia radio connection.

ELECTROSTATIC WARNING:
The MSP430-CCRF board is shipped in protecti e anti-static packaging. The board
must not be subject to high electrostatic potentials. General practice for working
with static sensiti e de ices should be applied when working with this board.
BOARD USE REQUIREMENTS:
Cables: The cable you will need depends on the programmer/debugger you
would use. If you use MSP-JTAG-TINY-V2 or MSP-JTAG-ISO-MK2, you will need
USB A-B cable. If you use MSP-JTAG, you will need LPT cable.
Hardware: Programmer/debugger MSP-JTAG-TINY-V2, MSP-JTAG-ISO-MK2 or
other compatible programming/debugging tool.

SCHEMATIC:

BOARD LAYOUT:
POWER SUPPLY CIRCUIT:
MSP430-CCRF can take power from:
–External power supply ia PWR connector 4 - 12 VDC
–JTAG
The programmed board power consumption is about 25 mA with all peripherals
enabled.
RESET CIRCUIT:
MSP430-CCRF reset circuit includes R2 (330Ω), R1 (33k), C1 (2.2nF), JTAG pin 11
and CC430F5137IRGZ pin 40 (#RST/SWBTDIO).
CLOCK CIRCUIT:
Quartz crystal Q1 32.768 kHz is connected to CC430F5137IRGZ pin 44 (P5.0/XIN)
and pin 43 (P5.1/XOUT).
Quartz crystal Q3 26 MHz is connected to CC430F5137IRGZ pin 25 (RF_XIN) and
pin 26 (RF_XOUT).

JUMPER DESCRIPTION:
J1
This jumper, when is in position 1-2 – UEXT pin 3 (signal TX) is connected to
CC430F5137IRGZ pin 5 (signal BSLTX/UCA0TXD); when the jumper is in position
2-3- UEXT pin 3 (signal TX) is connected to CC430F5137IRGZ pin 6 (signal
BSLRX/UCA0RXD)
Default state is shorted in position 2-3.
J
This jumper, when is in position 1-2 – UEXT pin 4 (signal RX) is connected to
CC430F5137IRGZ pin 6 (signal BSLRX/UCA0RXD); when the jumper is in position 2-
3 - UEXT pin 4 (signal RX) is connected to CC430F5137IRGZ pin 5 (signal
BSLTX/UCA0TXD)
Default state is shorted in position 2-3.
When jumpers J1 and J2 are shorted in position 1-2 – the board is configured as host and can
be used as host for some of our module boards. When these jumpers are shorted in
position 2-3 – the board is configured as de ice and can be used as module board.
P_OUT/P_IN
This jumper P_OUT/P_IN jumper declares if the board has to be powered externally
ia the JTAG debugger or it is internally powered.
Default state is shorted in position 2-3.
It is safer to switch the P_OUT position when you do not want to pro ide power ia the JTAG
debugger.
INPUT/OUTPUT:
Status Led with name LED (red) connected to CC430F5137IRGZ pin 13
(P1.0/PM_RFGDO0).
User button with name BUT connected to CC430F5137IRGZ pin 12
(P1.1/PM_RFGDO2).
