The CC1180 is a cost-effective, low power, sub-1GHz 6LoWPAN Network Processor that provides 6LoWPAN functionality with a minimal development effort.
The CC1180 is a preloaded version of CC1110F2, where the TI third party Sensinode’s 6LoWPAN stack, NanoStack 2.0 Lite, runs on the CC1180 Network Processor. The application controlling the network processor runs on an external host microcontroller. The CC1180 handles all the timing critical and processing intensive 6LoWPAN protocol tasks, and leaves the resources of the application microcontroller free to handle the application.CC1180 makes it easy to add 6LoWPAN functionality to new or existing products at the same time as it provides great flexibility in choice of microcontroller.
CC1180主要特性:
Simple Integration of 6LoWPAN with Mesh Support into Any Design

This document describes the TI 6LoWPAN evaluation kit for use in the 868/915MHz bands. The kit is based on hardware from TI and 6LoWPAN software (NanoStack) from TI third party Sensinode Ltd.
The CC-6LOWPAN-DK-868 kit provides easy way for users to start developing their own wireless sensor network applications based on 6LoWPAN technology. There are two different APIs for communicating with the NanoStack, based on if you use CC1180 Network Processor or the CC430 SoC. The API used for CC1180 is called NAPSocket, while the API for CC430 is called NanoSocket.
The kit contains a 6LoWPAN Edge Router (access point/gateway to IPv6) based on TI?s OMAP-L138 processor. The Edge Router (ER) uses a CC1180EM as radio interface. The Edge Router is running Sensinode Ltd NanoRouter 2.0 software and can connect wireless sensor nodes running Sensinode Ltd NanoStack 2.0 lite. The evaluation version of NanoRouter 2.0 included in the kit is limited to 10 nodes per Edge Router.
Included in the kit are two EM430F5137RF900 Rev 3.2 boards and two CC1180DB boards. The EM430F5137RF900 and CC1180DB boards are used as wireless sensor devices in the kit. CC430 comes with library support for Sensinode NanoStack 2.0 lite (NanoSocket [8]). This library model allows easy implementation of user applications, built directly on top of the NanoSocket library.
The CC1180DB contains a Wireless Network Processor (WNP), CC1180, which handles all 6LoWPAN network communication. Connected to the WNP is a host processor (MPS430F5438A) running the user application. The hardware interface between the network processor and the host processor is UART. The software interface between the network processor and the host MCU is Sensinode NAPSocket API [12]. The NAPSocket API acts as a wrapper library to parse Sensinode NAP protocol messages [9].
The kit provides Edge Router (NanoRouter) control and testing software (Sensinode NodeView 2.0 [10]). NodeView 2.0 can be used to control NanoRouter software running on the Edge Router in real time and provides e.g. address information of the connected nodes. The control protocol is based on Sensinode proprietary UDP communication. The NodeView 2.0 tool also provides a simple way to create user?s own java applications that are included in the NodeView 2.0 GUI in the form own separate tabs.
All nodes can act as routers inside the 6LoWPAN network. The radio transceivers on the nodes are thus always on, which makes the system less suitable for battery-powered devices.
CC1180主要特性:
IP-based networking, enabling the “Internet of Things”
CC1180 Over-Network Download (OTA), future proofs:
o Device applications and network upgrades
Low memory footprint;
o CC1180 6LoWPAN stack is less than 32kB
o CC430 6LoWPAN stack is about 17kB
Sensinode 6LoWPAN software can run on all frequencies that CC1180 and CC430 support, providing a sub-GHz mesh solution. Note: The kit hardware is for use in the 868/915 MHz bands.
Low development complexity, customers used to IP programming will be up and running in no time with the simple socket API approach.
Configurable RF interface:
o Output power: -30dBm to +10dBm
o Date rates: 50, 100, 150 and 200kbit/s
o RX Attenuation, for close-in systems
