STMicroelectronics has introduced an ARM-based, single chip, stand-alone GPS IC called Teseo II, for portable navigation devices and automotive telematics.
.
"Teseo II is the world's first single-chip solution able to acquire and track signals from satellites of multiple global navigation systems, including GPS, GLONASS and QZSS that are operational today, as well as Europe's upcoming GALILEO," says Fabio Marchio, ST’s automotive product group vp.
The chip’s ability to acquire the position, velocity and time data from all major global navigation systems greatly improves the user position accuracy and navigation in poor satellite visibility conditions, such as in urban canyons, says ST.
The Teseo II chips also claims to have short signal-acquisition times (Time To First Fix).
The chip is aimed at personal naviagation devices, GNSS modules, marine equipment, fitness devices, in-car navigation, telematics, eCall and Advanced Driver Assistance Systems.
Automotive-grade product versions, qualified to AEC-Q100, designed to meet the specific and rigorous demands of the automotive market, are available.
The chips use an ARM9 core for on-chip data processing. Peripherals include USB 2.0, CAN (Controller Area Network), A/D converter, I(2)C, MSP (Multi-channel Serial Port), UART (Universal Asynchronous Receiver-Transmitter) and general-purpose I/Os.
Samples of ST's Teseo II receivers (STA8088EX) are available and volume production is scheduled for Q3 2011. Unit pricing of the STA8088EX is below $6 for volumes in the range of 500,000 pieces
