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. To meet the various needs required by these wireless systems, Texas Instruments Inc. (TI) has launched the low-cost, sub-1GHz CC11x1-Q1 device family designed for very low-power, high-range wireless and car access systems. The devices include 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.
All devices are pin-to-pin and software compatible, allowing easy migration from unidirectional to bidirectional systems with a simple software upgrade. The products feature extended temperature range of up to +125°C, and are qualified in accordance with AEC-Q100 temperature Grade 1.
The devices will enable designers to build high reliable data links with a fast frequency hopping scheme (88µs switching time) utilizing the fractional-N concept. Typical receiver sensitivity is up to -114dBm. The UHF devices also feature programmable data rate from 1.2kBaud to 250kBaud, with ASK, OOK, FSK, GFSK and MSK modulations.
