Product details
Overview
TESEO-VIC3DA from STMicroelectronics is an AEC-Q100 qualified automotive GNSS dead-reckoning module integrating a Teseo III GNSS receiver, 6-axis inertial sensor (ASM330LHH), TCXO, RTC, and 16 Mb stacked flash. It delivers 1.5 m CEP autonomous positioning, -163 dBm tracking sensitivity, and 30 Hz dead-reckoning fix rate for tunnel/urban canyon navigation. Used in automotive telematics, ADAS map-matching, and fleet tracking systems.
For engineers reviewing the TESEO-VIC3DA datasheet, TESEO-VIC3DA pinout, TESEO-VIC3DA application, or TESEO-VIC3DA equivalent, key selection criteria include AEC-Q100 qualification, simultaneous GPS/Galileo/GLONASS/BeiDou/QZSS support, embedded DRAW firmware, 17 μA standby current, and LCC-24 package compatibility with automotive thermal (-40°C to +85°C) and mechanical requirements.
Technical Context
The TESEO-VIC3DA implements a tightly coupled GNSS/IMU fusion architecture using ARM-core firmware (TESEO-DRAW) that processes raw accelerometer and gyroscope data from the integrated ASM330LHH alongside multi-constellation satellite measurements. Its dedicated RTC oscillator enables sub-2-second hot TTFF and supports periodic low-power wake-up modes.
Signal acquisition leverages a high-stability TCXO for RF down-conversion and timing integrity, while dual UART, I²C, and configurable GPIOs (WHEELTICK, FWD, PPS) enable direct odometer integration and NMEA-based host communication. Firmware configurability allows runtime selection of constellations, SBAS services (WAAS/EGNOS/GAGAN/MSAS), and assisted GNSS modes (ST-AGNSS up to 7-day prediction, RT-AGNSS via server).

Equivalent & Alternatives
The following parts are listed as comparable options for similar GNSS dead-reckoning applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| u-blox UDR7 | Supports GPS/Galileo/GLONASS only; no BeiDou/QZSS; uses external IMU; no embedded flash for firmware updates | Targeted at industrial asset tracking, not AEC-Q100 automotive systems | Select when multi-constellation flexibility is secondary to cost and legacy u-blox ecosystem integration |
| Texas Instruments CC2652RB | Bluetooth SoC with integrated crystal; lacks dedicated GNSS/IMU; requires external GNSS module and sensor fusion software | Designed for low-power IoT nodes, not automotive-grade positioning | Select when BLE connectivity dominates over high-accuracy dead reckoning and GNSS autonomy |
Compared with u-blox UDR7 and TI CC2652RB, TESEO-VIC3DA uniquely integrates AEC-Q100 qualification, multi-constellation GNSS, 6-axis IMU, TCXO, RTC, and flash in a single LCC-24 package - eliminating BOM complexity and validation effort for automotive OEMs.

FAQ
What GNSS constellations does TESEO-VIC3DA support simultaneously?
TESEO-VIC3DA supports simultaneous reception and tracking of GPS L1C/A, Galileo E1B/C, GLONASS L1OF, BeiDou B1, and QZSS L1C/A signals. Firmware configuration allows selective activation of constellations; default is GPS+GLONASS. Concurrent BeiDou and GLONASS are mutually exclusive per design, but either may run with GPS and Galileo.
How is dead reckoning implemented and what inputs does it require?
Dead reckoning is implemented via embedded TESEO-DRAW firmware that fuses raw 6-axis IMU data (from the integrated ASM330LHH) with GNSS measurements. Required inputs include WHEELTICK (pin #4) for odometer pulses and FWD (pin #15) for forward/reverse direction detection. Optional map-matching feedback can be provided via host processor to further refine position estimates during GNSS outages.
Does TESEO-VIC3DA support assisted GNSS, and what types are available?
Yes, TESEO-VIC3DA supports two assisted GNSS modes: ST-AGNSS (ST-Assisted GNSS) and RT-AGNSS (Real-Time Assisted GNSS). ST-AGNSS uses internally predicted ephemeris (up to 7 days) derived from previously downloaded satellite data. RT-AGNSS downloads real-time ephemeris from an external server via UART or I²C using proprietary NMEA commands and credentials provided by STMicroelectronics partners.
What is the role of the VCC_RF pin and how should it be used?
VCC_RF (pin #9) is a 3.3 V regulated output supplying power to external active GNSS antennas. It remains active during software standby mode, so host firmware must assert Ant_OFF (pin #14) to disable the antenna and prevent unnecessary current draw. During VCC standby (main supply off), VCC_RF is inactive, eliminating antenna power leakage entirely.
