Toshiba Launches New Single-Chip RF/IF Receivers for Short-Range, Low-Power Wireless Applications
Low-Cost, High-Sensitivity Devices Combine AM or AM/FM Comparators, RF Amplifier and Local x8 Circuit in a Small Package
SAN JOSE, Calif., April 21 /PRNewswire/ -- Toshiba America Electronic Components, Inc. (TAEC)* today announced it has broadened its wireless product lineup with the introduction of a pair of new radio frequency (RF)/intermediate frequency (IF) receivers that operate at 240 megahertz (MHz) to 450MHz and provide high-sensitivity with low-power consumption. TA31275FN is an RF/IF detector integrated circuit (IC) for AM/FM radio while TA31273FN is an RF/IF detector IC for AM radio only. Both low-cost monolithic devices incorporate an RF amplifier, a two-level comparator and a local x8 circuit. They are targeted at a wide range of short-range, low-power wireless applications, including remote keyless entry systems, tire pressure monitoring systems, telemetry and RF metering.
"Wireless products are becoming a pervasive part of consumers' lives. The burgeoning list of wireless products ranges from remote locks, security systems, tire pressure monitoring systems and gate openers to wireless keyboards, mice, telemetry and light switches," said Farhad Mafie, vice president of the ASSP Business Unit at TAEC. "As manufacturers rush to bring new devices to market, they face constant pressure to provide high-performance products at lower cost. Toshiba's new low-power, low-cost data communication devices give customers a head-start on adding short-range wireless functionality to a host of existing and new applications without expensive re- wiring."
"We believe our new TA31273FN and TA31275FN receivers provide the right blend of low-cost, high-sensitivity, low-power consumption and essential features. We are pleased that we have already achieved design wins in the automotive segment for remote keyless entry and tire pressure monitoring applications," said Abdul Aslami, business development manager in the ASSP Business Unit at TAEC.
Pricing and Availability
Samples of TA21273FN and TA31275FN are currently available in both sample and volume production quantities. Each device is priced at $0.99 per piece in 10,000-piece quantities.
