TI Brings Low Power and High-Distance Range to Wireless Car Access Systems with Low-Cost UHF Device Family
New CC11x1-Q1 family provides increased visibility for vehicle safety and maintenance with simple RF design and an easy-to-use SPI interface
DALLAS (October 13, 2009) - Consumers demand timely visibility into their vehicle status to ensure their car is properly maintained resulting in today's vehicle architecture containing a wide range of wireless applications such as tire pressure monitoring, auxiliary heating remote control and key features such as garage door openers or the standard remote control. In order to meet the various needs required by these wireless systems, Texas Instruments Incorporated (TI) (NYSE: TXN) today announced the low-cost, sub-1GHz CC11x1-Q1 device family. Designed for very low-power, high-range wireless and car access systems, this new device family includes UHF transmitters, receivers and transceivers. With a simple RF design and an easy-to-use SPI interface, the CC11x1-Q1 family does not require external filters or switches which results in a low-cost design.

Key features and benefits of the CC11x1-Q1
All devices are pin-to-pin and software compatible, allowing easy migration from unidirectional to bidirectional systems with a simple software upgrade.
Extended temperature range (up to +125° C) sustains the device as vehicle temperatures flex. All parts are qualified in accordance with AEC-Q100 temperature Grade 1.
Designers can build high reliable data links with a fast frequency hopping scheme (88µs switching time) utilizing the fractional-N concept.
No external filters, switches or voltage-controlled oscillators are required, resulting in only a few external components and low-cost designs.
Typical receiver sensitivity up to -114dBm provides an increased communication range.
Programmable data rate from 1.2 - 250kBaud brings flexibility to all applications with ASK, OOK, FSK, GFSK and MSK modulations.
Automatic frequency compensation adds to ease of use and reliability.
Embedded Packet Handler with support for sync word detection and automatic CRC allows for easy design and relaxed microcontroller requirements.
Digital RSSI output opens the door for further applications.
Pricing and availability
Pricing of the CC11x1-Q1 device family starts at $1.10 for 100k of the CC1151IRHBRG4Q1. These devices are available in a QFN 5x5mm, 32-pin package, resulting in the smallest board space for UHF transceivers on the market. For additional questions and support, visit www.ti.com/rfid_support.
