TI brings low power and high-distance range to wireless car access systems with low-cost UHF device family

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, TI announces 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.
