Description
STA8088EXG is a single die standalone
positioning receiver IC working on multiple
constellations (GPS/Galileo/Glonass/QZSS).
By combining the ARM946 microcontroller core
with the large number of peripherals/ interfaces,
STA8088EXG provides a highly-flexible and cost
effective solution for hand-held and telematic
applications.
The device is the ideal solution for sensor-based
and sensor-less ST Dead Reckoning
technologies which enhance positioning accuracy
even in areas without GNSS signals, like tunnels
and indoor parking.

STA8088EXG
1 Overview
Overview
STA8088EXG is an integrated System-On-Chip device designed for a highly-flexible and
cost effective solution for vehicle, hand-held navigation and telematic applications.
It combines a high performance ARM946 microprocessor with embedded enhanced
peripherals and I/O capabilities, RF front-end and base band processor to support GPS,
Galileo, Glonass and QZSS satellite systems.
It also provides clock generation via PLL, backup logic with real time clock and it supports
USB2.0 standard at full speed.
STA8088EXG is software compatible with the ARM processor family. 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 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.
I/O lines are compatible with 1.8 V and 3.3 V.
The chip, using STMicroelectronics CMOSRF technology, is housed in a TFBGA169
(9 x 9 x 1.2 mm) and TFBGA169 (12 x 12 x 1.2 mm) packages.
The Automotive Grade devices (see Figure 4: Ordering information scheme) fulfilling high
quality and service level automotive market requirements, is the ideal solution for OEM
telematic applications.
