AN-1050: EnerChip™ EH with TI LaunchPad
CBC-EVAL-11 EnerChip CC Inductive Charger
CBC-EVAL-11 (shown in Figure 5) is a demonstration kit combining an RF inductive transmitter board with a receiver
board containing an EnerChip CC CBC3150 solid state storage device with integrated power management. The
transmitter board operates at 13.56 MHz and derives its power from a USB port. In addition to the EnerChip CC,
the receiver board has a planar antenna for receiving power from the transmitter board, an output capacitor for
delivering pulse current for radio transmissions, and a header connector for mating to a target board containing,
for example, a microcontroller and/or radio board. The CBC-EVAL-11 data sheet can be found at:
http://www.cymbet.com/content/products-resource-docs.asp. The EVAL-11 is available at Avnet, Digi-Key and
Mouser.
Connecting the CBC-EVAL-11 to the TI LaunchPad
After connecting the TI LaunchPad to a PC via the USB cable, it must be disconnected before connectiing the
EVAL-11 to the LaunchPad.
The white cable included in the EVAL-11 kit is used to connect the two kits together. Note the orientation of the
EVAL-11 to the TI LaunchPad. The cable is placed over all five pins on EVAL-11 J4 connector and all three pins on
the TI LaunchPad J6 connector. Ensure that pin 5 on the EVAL-11 J4 connector is connected to VCC pin on the
LaunchPad.
Also, in order to avoid EH powering the entire TI LaunchPad board vs. just the MSP430 MCU, the LaunchPad J3
VCC and RST connector jumpers must be removed and set aside. These are to be restored for USB operation.
