Description
STA8088GA is a single die standalone positioning
receiver IC working on multiple constellations
(GPS/Galileo/Glonass/QZSS).
The device is compliant with ST Automotive
Grade which in addition to AEC-Q100
qualification includes a set of production flow
methodology targeting zero defect per million.
STA8088GA, fulfilling high quality and service
level Automotive market requirements, is the ideal
solution for in-dash navigation and OEM telematic
application.
The device is offered with a complete GNSS
firmware which performs all GNSS operations
including tracking, acquisition, navigation and
data output with no need of external memories

STA8088GA
1 Overview
Overview
STA8088GA is a highly integrated System-On-Chip device designed for positioning systems
applications.
It combines the high performance of 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 processors 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.
STA8088GA 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 and the backup logic. In order to reduce the power consumption the
chips can be directly powered with 1.2V bypassing the embedded voltage regulators which
will be put in power down mode.
I/O lines are compatible with 1.8V and 3.3V.
STA8088GA, using STMicroelectronics CMOSRF Technology, is housed in either
VFQFPN56 (7 x 7 x 0.85 mm) or VFQFPN56 (8 x 8 x 0.85 mm) packages.
STA8088GA is compliant with ST Automotive Grade which in addition to AEC-Q100
qualification includes a set of production flow methodology targeting zero defect per million.
STA8088GA, fulfilling high quality and service level Automotive market requirements, is the
ideal solution for in-dash navigation and OEM telematic application.
