Solutions Guide
The Texas Instruments (TI) portfolio of MSP430™ microcontrollers and Low-Power RF devices are an ideal fit for low-power wireless networks, including
standard-based IEEE 802.15.4 and ZigBee
®
or other proprietary networks. The MSP430 product line offers the unique combination of ultra-low power
consumption with a high-performance 16-bit CPU and integrated analog. Together, MSP430 and TI’s Low-Power RF devices help wireless designers
achieve low power, long range and reliably performing designs at a competitive price. TI also offers the CC430 family of sub 1 GHz system-on-chip
monolithic devices that integrate the MSP4305xx microcontroller with a flexible Low-Power RF transceiver, offering you more performance in less space.

System-on-Chip Solutions
The CC430 is the industry’s highest performance, single-chip, low-power RF solution. It is based on the new 5xx generation of ultra-low-power MSP430
microcontrollers, with a high level of peripheral integration, outstanding analog performance and ease of use. The 5xx core is paired with the flexible
CC1101 sub-1GHz transceiver to deliver the sensitivity and blocking performance required to achieve a robust communication link in any RF environment.
The CC430 enables the user to minimize RF power, size, and cost requirements while still maintaining superior application performance. TI also offers
8051-based System-on-Chip solutions. For IEEE 802.15.4 and ZigBee networks, use CC2530.
Supported Standard-Based Networks
• IEEE802.15.4–Awirelessradiofrequencystandardforlow-power
and short-range applications. This standard is ideal for point-to-point or
point-to-multipoint networks. Systems that start with an 802.15.4-based
proprietary network can later be upgraded with new software and evolve
to a ZigBee-compliant system. TIMAC software and packet sniffer
are included for free with the protocol.
• ZigBeePRO–Alow-powerwirelessnetworkstandardthatoffers
mesh networking as well as interoperability between different vendors’
products. ZigBee is a network layer on top of the IEEE 802.15.4
standard (PHY and MAC layers). The new Advanced Metering
Infrastructure (AMI) profile and the Home Automation profile are a
perfect fit for a powerful combination of smart metering and home
automationservices–basedonaworldwidestandard.Z-Stack™
software and packet sniffer come bundled for free.
Proprietary Networks
• SimpliciTI™NetworkProtocol–Thisfreesoftwarecodeandpacket
sniffer, an excellent start for building a network, is battery operated
and was designed to be used with TI Low-Power RF system-on-chips
or the MSP430 and an RF transceiver. SimpliciTI network protocol is a
simple and versatile solution, combining MSP430+CC1101/2500,
CC1110/2510 and CC2520 DSSS parts, and offering applications
such as alarm systems, smoke detectors and active RF-ID applications.
Passive Standard-Based Networks
•ISO18000-2–ThisPassiveRFair-interfaceprotocolenablesshort-range
two way communication without the need of a battery by scavenging the
RF energy transmitted from a base-station. It is ideal for data-logging
applications (configuring a device without the need of a battery), for
medical applications (non-battery operated bio-sensors) and as a method
for recharging batteries while enabling two way communications.
