STA8088FG is a highly integrated System-On-Chip device designed for positioning systems applications. The low power consumption and minimum BOM make STA8088FG the ideal solution for low-cost and battery-operated portable products such handheld， computers， cameras， data loggers and sports accessories， as well as automotive application. It combines a high performance ARM946 microprocessor with embedded enhanced peripherals and I/O capabilities with ST next generation triple-constellation positioning engine. The RF front-end and base band processor are able to support GPS/Galileo and Glonass navigation systems. The device is offered with a complete firmware which performs all positioning operations including tracking， acquisition， navigation and data output with no need of external memories. It also provides clock generation via PLL， backup logic with real time clock and it supports USB2.0 standard at full speed， （12 Mbps） with on-chip PHY. STA8088FG is software compatible with the ARM processor family. The device is power supplied with 1.8V and uses three on-chip voltage regulators to internally supply the RF front-end， core logic and the backup logic. In order to reduce the power consumption the chip can be directly powered with 1.2 V bypassing the embedded voltage regulators which will be put in power down mode. I/O lines are compatible with 1.8 V and 3.3 V. The chip， using STMicroelectronics CMOSRF Technology， is housed in a VFQFPN-56 （7 x 7 x 0.85 mm） package with stacked 16 Mbit Flash memory
