Introduction

Thank you for purchasing a CC254x Development Kit. The current development kits in the CC254x
family described here are the CC2543-CC2544DK, the CC2545EMK and the CC2541EMK. The
Evaluation Module Kits (EMK) are supplementary to the CC2543-CC2544DK as they only consist of
two single Evaluation Modules (EM).
The CC2543, CC2544 and CC2545 devices are RF SoCs designated for the proprietary 2.4 GHz RF
market that can be used in any application, but are tailored for wireless HID applications. The CC2544
is tailored for the USB dongles, the CC2543 for peripheral devices such as wireless mouse
applications and the CC2545 for wireless keyboard applications.
The single-chip RF transceiver and MCU supports data rates up to 2Mbps, and has extensive
baseband automation, including auto-acknowledgement and address decoding. It provides excellent
link budget with programmable output power up to +5 dBm, which enables long range without external
front-ends.
The CC2543, CC2544 and CC2545 devices come with a two-channel DMA which reduces the need of
the MCU operating in active mode, hence significantly improves power consumption. In addition they
have one 16-bit and two 8-bit timers and 20mA drive strength on selected general purpose I/O pins.
They also have a 40-bit radio timer used by the Link Layer Engine.
The on-chip voltage regulator supports a wide range of supply voltages, and the CC2544 has a USB
5V to 3.3V regulator. The on-chip MCU is the High-Performance and Low-Power 8051 Microcontroller
with Code Prefetch.
The CC2544 has full speed USB support with 6 endpoints, separate 1kB FIFO memory, internal pull-
up and 5V to 3.3V regulator.
The CC2543 [1], CC2544 [2] and CC2545 [3] product folders on the web have more information, with
datasheets, user guides and application notes.
The CC2543-CC2544 Development Kit includes all the necessary hardware to properly evaluate,
demonstrate, prototype and develop software for proprietary applications

About this manual

This manual describes all the hardware included in the CC2543-CC2544 Development Kit (CC2543-
CC2544DK), the CC2545 Evaluation Module Kit (CC2545EMK) and points the user to other useful
information sources.
The CC2541 Evaluation Module Kit (CC2541EMK) is also compatible in similar fashion as the
CC2545EMK. The CC2541 device has two different modes of operation called "BlueTooth Low Energy
Mode" and "Proprietary Mode". This user guide only covers the "proprietary Mode" of operation and it
does not detail the HW and specific details of the CC2541. The CC2541 has more system resources
available (256kB FLASH and 8kB RAM size to mention some). Proprietary applications that require
more system resources than what the CC2543/44/45 can offer might want to consider using the
CC2541. For more information about the CC2541 and the CC2541EMK please visit the product folder
page on web and the CC2541EMK web page.
Chapter 4 briefly describes the contents of the development kits and chapter 5 gives a quick
introduction to how to get started with the kit. In particular, it describes how to install SmartRF Studio
to get the required drivers for the evaluation board, how the hardware can be used, and lists the
software that is available for the development kit. Chapter 6 explains some simple methods for
performing practical RF testing with the development kit. Chapter 7, 8, and 10 describe the hardware
in the kit and where to find more information about how to use it. A troubleshooting guide can be found
in chapter 11.
