Product details
Overview
STA8089GAT from STMicroelectronics is an AEC-Q100 Grade 2 qualified, single-die automotive GNSS receiver IC supporting GPS, Galileo, GLONASS, BeiDou, and QZSS with 48 tracking + 2 fast-acquisition channels, -162 dBm indoor tracking sensitivity, and sub-1-second hot-start TTFF - deployed in OEM telematics and in-dash navigation systems.
For engineers reviewing the STA8089GAT datasheet, STA8089GAT pinout, STA8089GAT application, or STA8089GAT equivalent, key selection considerations include multi-constellation timing accuracy under urban canopy, integrated ARM946 MCU (196 MHz), dual CAN 2.0B interfaces, USB 2.0 full-speed PHY, and VFQFPN56 package compatibility with STA8088GA.
Technical Context
The STA8089GAT integrates a G3BB+ baseband processor handling simultaneous Galileo/GPS (4.092 MHz IF), GLONASS/BeiDou (8.57/10.23 MHz IF) signal processing with sign-magnitude 3-bit ADC digitization and on-chip VGA gain control via SPI. Its RF front-end embeds LNA, synthesizer, and LDOs for 1.2 V RF core supply.
The ARM946E-S MCU subsystem operates up to 196 MHz with 256 KB SRAM, dual UARTs, I²C master/slave, two 10-bit ADC channels, RTC, watchdog timer, and SQI interface for external flash - all powered across five regulated domains (VINL, VINB, VDD, VCC, VddIO) meeting -40/+105°C automotive operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar GNSS receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STA8088GA | Pin-to-pin compatible but lacks QZSS support and has lower RF sensitivity (-160 dBm) | Legacy automotive navigation where QZSS coverage is non-critical and cost sensitivity is higher | Select when backward compatibility with existing STA8088GA designs is required and QZSS is not needed |
| u-blox UBX-M8030-KT | Supports same constellations but uses external MCU; no integrated ARM946 or CAN interfaces | Systems requiring modular GNSS + separate application processor architecture | Choose when design flexibility outweighs integration benefits and CAN bus connectivity is handled externally |
Compared with STA8088GA, STA8089GAT adds QZSS and improves sensitivity by 2 dB for better urban performance; versus u-blox M8030, it eliminates external MCU and CAN transceivers but requires firmware development for the ARM946 subsystem.

FAQ
Is STA8089GAT pin-compatible with STA8088GA?
Yes, STA8089GAT is pin-to-pin compatible with STA8088GA per ST's official documentation, enabling drop-in replacement in existing PCB layouts. Both share identical VFQFPN56 packaging, power pin mapping, and peripheral interface pinouts - though STA8089GAT adds QZSS support and improved RF sensitivity without altering footprint or routing.
What GNSS constellations does STA8089GAT support natively?
STA8089GAT natively supports GPS (L1 C/A), Galileo (E1), GLONASS (L1), BeiDou (B1I), and QZSS (L1 C/A) - all processed concurrently by the G3BB+ baseband engine. It does not support SBAS (WAAS/EGNOS) or dual-frequency (L2/L5) signals, and requires no external firmware patches to enable any of these five systems.
Does STA8089GAT include an integrated USB PHY?
Yes, STA8089GAT integrates a full-speed USB 2.0 physical layer (PHY) compliant with USB specification 2.0, supporting 12 Mbps data transfer. The USB_DP and USB_DM pins connect directly to a USB connector without external transceivers, and the embedded PHY handles line termination, differential signaling, and enumeration under host control.
What is the role of the dual CAN interfaces in STA8089GAT?
The two independent CAN 2.0B controllers (CAN0 and CAN1) provide native vehicle bus connectivity: CAN0 typically interfaces with powertrain or chassis ECUs for synchronized timing, while CAN1 connects to infotainment or telematics domains. Each channel features dedicated TX/RX pins, configurable bit rates up to 1 Mbps, and built-in message filtering - eliminating need for external CAN transceivers.
