docid022668 rev 5 5/15 STA8088TG overview 14 1 overview STA8088TG is a highly integrated system-on-chip device designed for positioning systems applications. the embedded sram combined with a high performance arm946 microprocessor allows the running of acquisition/tracking tasks without the need of external flash. the rf front-end and gnss engines are able to support simultaneously gps/galileo/glonass and qzss navigation systems. the device is power supplied with 1.8 v 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 3.3v. the chip, using stmicroelectronics cmosrf technology, is housed in vfqfpn56 (7 x 7 x 0.85 mm) package. the st automotive grade devices (see figure 4: ordering information scheme ) with in addition to aec-q100 qualification include a set of production flow methodology targeting zero defect per million. they, fulfilling high quality and service level automotive market requirements, are the ideal solution for in-dash navigation and oem telematic application. STA8088TG family enables telematic and handset manufacturers to differentiate in the market by providing the best performing solution at lowest system cost.
