1 Introduction

Thank you for purchasing a development kit for Low Power RF System-on-Chips from Texas Instruments.

2 About this Manual

This manual covers the CC1111 USB Dongle or the CC2511 USB Dongle found in the CC1110­CC1111DK/CC2510-CC2511DK development kits. Both these USB dongles are also available separately
as the CC1111EMK868-915 and CC2511EMK evaluation module kits.

The manual covers the CC1111/CC2511 USB Dongle hardware component of a USB development
framework. Please refer to [5] and [6] for a description of the accompanying software library and
application examples.

SmartRF04EB CC1110EM/CC2510EM

Evaluation Board. Main board in the development
kits, USB interface, LCD, LEDs, pot-meter etc.
Development platform for the Evaluation Modules
(EM).

CC1110 and CC2510 Evaluation Module are small
modules for the CC1110 and CC2510 devices.
These can be plugged into the SmartRF04EB and
they should be used as the reference design for
antenna and RF layout.

CC1111/CC2511 USB Dongle System-on-Chip Debug Plug-in Board

A reference design for a CC1111/CC2511 based
full-speed USB dongle with RF interface. Should
be used as reference design for antenna and RF
layout.

The System-on-Chip Debug Plug-In Board. It
provides an additional physical
debug/programming interface for the
SmartRF04EB. Referred to as SOC_DEM in this
document.

Figure 1. Kit Hardware Component Overview

SoC System on Chip. A collective term used to refer to Texas

Instruments ICs with on-chip MCU and RF transceiver. Used
in this document to reference the CC1111/CC2511 and the
CC1110/CC2510.

ICE In Circuit Emulator. ICE functionality is built into the

SmartRF04EB.

USB Software Application Examples Application examples using the CC1111/CC2511 USB

Dongle together with a CC1110/CC2510EM.

USB Firmware Library A library of low level USB firmware which is used by all the

USB software examples.
