3.2.4. Serial EEPROM (U1)
A 128Kbit (16K x 8) serial EEPROM is provided for applications that require storing data in
nonvolatile memory. Please refer to the AT24C128C datasheet on the Atmel website for further
info regarding this device.
The I
2
C bus address of this device is 0x50.
3.2.5. LED Indicators

Red LED (D1)
Duplicate of Red LED on MSP430 LaunchPad. Controlled by MSP430 P1.0 (J1.2)
–
active high.

Green LED (D2)
Duplicate of Green LED on MSP430 LaunchPad. Controlled by MSP430 P1.6 (J2.4)
–
active high. This LED is shared with the SPI MISO signal and is therefore unusable
without modification to the SPI driver.

Yellow LED (D3)
Controlled by MSP430 P2.4 (J2.2)
– active low. This LED is shared with the I 2
C SCL
signal and is only usable when not using I
2
C.

Tri-Color LED (D4)
When using a MSP430 the Tri-Color LED can be pulse width modulated (PWM) to
produce a wide range of colors. This capability is not available when the BoosterPack is
used with a Stellaris LaunchPad due to lack of PWM capability on the chosen pins. In
this situation, the Tri-Color LED on the Stellaris LaunchPad will need to be used instead
for applications requiring multiple colors. The BoosterPack Tri-Color LED is controlled
as follows:
Red Segment
– MSP430 P2.1/TA1.1 (J1.9) – active low.
Green Segment
– MSP430 P2.5/TA1.2 (J2.3) – active low.
Blue Segment
– MSP430 P2.6/TA0.1 (J2.9) – active low.

A2530 Red LED (D8)
Controlled by A2530 P1.0 (GPIO3)
– active high.

A2530 Yellow LED (D9)
Controlled by A2530 P0.6 (GPIO2)
– active high.
