SiRFatlasIV™
For Automotive, PNDs and Telematics
Description
Delivering leadership navigation, 65nm process technology, and 500 MHz ARM11-fueled multimedia experiences, SiRFatlasIV™ targets entry to mid range location enabled convergence devices. This cost efficient single-chip solution also provides an integrated GPS baseband, integrated touch screen controller, and MLC Flash controller—a blend of affordability and advanced technology.
Key features
- High-performance GPS and Galileo location engine
- High-speed ARM11 CPU with floating point unit, 16 KB D/I cache, and 16 KB D/I TCM
- Supports QVGA H.264 mobile digital TV content and VGA MPEG4 video playback
- Advanced memory controller supports 166 MHz clock Mobile-DDR and 200 MHz clock DDR
- Embedded hardware for colour space conversion, deinterlace, and scaler
- 8-bit NAND flash interface with 8-bit BCH HW ECC support for direct boot from SLC or MLC NAND
- Integrated four port SD/MMC/MMC+ controller and support for direct boot
- High-speed USB 2.0 port with internal PHY configurable as host or slave
Benefits
- With the growing popularity of location centric devices, today’s mobile user demands better and cheaper navigation with value-added functions such as multimedia entertainment, Bluetooth, and real time communication capabilities such as RDS-TMC for traffic and weather information. The SiRFatlasIV multifunction product is designed to address all of these needs and in a cost-effective manner
- Powered by an ARM11 CPU with floating point unit and a location engine optimised for simultaneous tracking of GPS and Galileo satellites. Peak performance is ensured with a 64-bit system bus and a high-speed memory controller capable of supporting various DRAM modules including DDR 200/Mobile-DDR 166, providing adequate memory bandwidth for the most demanding application scenarios
- Built-in video post processing accelerator handles video rendering and display, allowing the powerful CPU to run at full horsepower for application processing. Popular mobile digital TV applications such as TDMB, DVB-H, and CMMB can run with no impact on CPU performance
- SLC/MLC NAND and SD controller design allow the system designer the flexibility to select either a low cost or a robust NAND product. With an embedded GPS baseband, touch-screen controller, ADC, and high speed USB PHY, a lower system cost can be achieved.
