CC264BPA is a high-performance and ultr
a low-power BLE 4.x data module which uses Texas Instrument’s
CC2640/CC2650 SoC as the main component. Its integrated PCB antenna further simplifies the system design to
provide users with a truly handy design block. All essential I/Os and power lines are wired out to the module pins. All I/O
functions are software configurable.
The r
eference application (TIEM) described in this section provides a typical usage example of the module. It
provides a hardware environment for CC264BPA module evaluation as well as facilitates the development of
firmware on the module. It is also compatible to TI’s SmartRF06 development board, CC2650DK Development Kit,
SensorTag Debugger DevPack, and is a near-drop-in replacement to CC2650EMK-5XD Evaluation Module. By
plugging in a CR2032 coin cell (not provided in the package) to the TIEM evaluation module, the board can run as a
standalone wireless device, providing simple function such as iBeacon. The breakout pins on the
E-interface allows further hardware feature extension. Actuator control, temperature and motion sensing, for example. This is a
perfect fit for quick prototyping Internet of Things (IoT) hardware demo.

Application Notes
Using coin cell battery as power source
If the TIEM evaluation module is running on CR2032 coin cell battery (i.e.VDD=3V or less), the logic
level of all IOs on E-interface will follow this VDD, which is determined by the battery level. If there is
any external hardware connected through the E-interface to the CC2640BPA module with logic levels
different from this battery level (e.g. connecting USB-UART dongle with 3.3v logic levels), power rail
mismatch problem may arise. In this case, it is suggested to supply 3.3v external power to DC power
input connection (J3) of TIEM and remove the coin cell battery.
Caution – Coin cell battery must be removed before applying 3.3V (max. allowable level) to DC
power input (J3) of the TIEM evaluation module.
Connection to JTAG debugger
CC26xBPA SMD and TIEM evaluation module support both compact JTAG (aka cJTAG) (2 wire) and
normal JTAG (4-wire). The JTAG pins on TIEM’s J6 and CC26xBPA module are (as specified in the
module datasheet):
TIEM_Pin_2, Module_Pin_11: JTAG_TMSC (used by cJTAG and JTAG)
TIEM_Pin_4, Module_Pin_13: JTAG_TCKC (used by cJTAG and JTAG)
TIEM_Pin_6, Module_Pin_14: DIO5/JTAG_TDO (used by JTAG only)
TIEM_Pin_8, Module_Pin_15: DIO6/JTAG_TDI (used by JTAG only)
Although the JTAG core signal pins (2-wire or 4-wire) are mandatory, your JTAG emulator may
requires other supporting pins to work probably. Please refer to TI's XDS Target Connection Guide
and your XDS100v3 JTAG enumerator manufacturer for the support. TIEM evaluation module’s J6
connector is a standard 10-pin ARM cortex header.
In general, in addition to the core signal pins, the following pins may need attention.
1. nRESET (Target Reset) - connect to CC2640's Reset pin (TIEM's J6 pin 10).
2. TDIS (Target Disconnect) - connect to the ground of the target (TIEM's J6 pin 9).
3. TVRef (Target Voltage Reference) - connect to the VDD of the target (TIEM's J6 pin 1).
