2DESCRIPTION
2.1 Overview
The Cordio BT4 Module and Customer Evaluation Base Board is based upon the CORDIO™ BT4
Development SoC which is a low power, 40 pin 5 x5 mm QFN that contains the BT4 Radio IP plus an ARM
Cortex M0+™ host MCU.
Figure 2.1 –Cordio BT4 Module
The BT4 Development SoC in on 42 pin Module which contains the necessary discrete RF components
around the BT4 radio IP block within the SoC, the SoC’s External EEPROM and a Reset Button. The majority
of pins of the SoC are various voltage rails and I/O signals that are taken directly to the pins on the module.
This modular approach is taken to easily upgrade to future Cordio products.
The Customer Evaluation Base Board or “Eval Board” is a platform for the Module to plug into which enables
the evaluation of BT4 Radio Hard Macro’s RF performance and the low power consumption characteristics.
Supported by a Bluetooth Smart® protocol stack from ARM®, the evaluation platform supports the choice of
either a test FW mode or an operational / demo FW mode.
Schematics and Bill of Materials for both boards can be found in the Cordio BT4 Module and Eval board
Schematics document included on the USB thumb drive provided in the Evaluation kit.

The platform can be powered from either an external 5v supply (Bench supply or USB cable) or from one of
three different types of batteries.
The board is mbed enabled allowing the user to utilize mbed tools and example source code as well as Keil
tools to develop custom FW for their ARM Cortex based SoC while it is still in development. It also supports
drag-n-drop FW programming of the Module.

3HARDWARE
Figure 3.1 - BT4 Customer Evaluation Board –Block Diagram
3.1 Block Diagram
The ARM Cordio BT4 Radio IP can be run in either a 1 volt or 3 volt mode/domain. The Cortex M0+Host
processor and its memories within the SoC are run at 1.2 volts. Level shifters are provided on all I/O buses to take
the SPI and I2C interfaces to 1.8 Volts and the UART and Serial Wire Debug lines to 3.3v. A separate mbed
controller from NXP runs at 3.3v and provides mbed development tools and drag-n-drop programming of the FW
for the BT4 Development SoC.
The entire block diagram is power-up when run in 5 volt line powered mode. Components within the red rectangle
are powered in any one of the three battery modes at 1.2 volts. The BT4 IP block is powered at either 1.0 or 3.3
volts depending on the S11 switch setting.
