STA8088FG
Overview
1
Overview
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.
