u‑blox has announced the TOBY-L4 series of Automotive Grade telematics modules. The series integrates LTE, UMTS and GSM connectivity with a powerful embedded processor, enabling a wide range of applications on a single device.
Connectivity is at the heart of the TOBY‑L4 LTE Cat 6 modules, providing full gateway capabilities in a single device capable of delivering up to 300Mbit/s data rates with carrier aggregation capability. Its extremely small 248-pin Land Grid Array (LGA) format measuring just 24.8mm by 35.6mm by 2.6mm meets the size/weight/power limitations of in-car applications.
The modules support both voice and data in the form of LTE, UMTS/DC-HSPA+, GSM, SMS and Voice (VoLTE and CSFB). With support for eCall (operating also at +95°C for at least 2 minutes) and ERA Glonass, the modules meets all the industry and carrier requirements in place today and are future‑proofed for all automotive OEM’s key regions.
With 19000 DMIPS and hardware virtualisation, the processor is powerful enough to safely and flexibly support Linux/Yocto distribution, enabling users’ software applications to run securely alongside a wide range of pre‑integrated communications protocols on the same device, enabling full application scalability without fear of hitting processor performance bottlenecks.
Security is a critical feature in any connected device and the new series addresses this through the integration of secure boot and update features, supported by a hardware cryptography accelerator and true random number generator. A dedicated trusted execution environment provides further security for system software and OEM applications. Thanks to its embedded processor and comprehensive range of interfaces including R(G)MII and analog audio, TOBY‑L4 removes the need for an additional processor and additional components in many applications, saving space, power and cost.
Manufactured in ISO/TS 16949 certified sites, the modules are qualified to ISO 16750 covering systems installed in vehicles, making them suitable for automotive OEMs.
The series of four modules provides comprehensive band configurations, allowing them to operate in all markets of the world, throughout North America, EMEA, APAC/Brazil and China.
