Datasheet

The TOBY-L4 series of automotive grade telematics modules has been announced by u-blox. 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 small 248-pin Land Grid Array (LGA) format measuring 24.8x35.6x2.6mm meets the size/weight/power limitations of in-car applications.

TOBY L4 supports 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 module meets all the industry and carrier requirements in place today and is future proofed for all automotive OEM’s key regions.

With 19,000 DMIPS and hardware virtualisation, the processor in TOBY L4 is powerful enough to safely and flexibly support Linux/Yocto distribution, enabling customer’s 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.

“The concept of the connected car is here,” commented Stefano Moioli, Director Product Management Cellular at u-blox. “The TOBY L4 series of LTE Cat 6 modules gives OEMs the ability to add connectivity with fully integrated applications in a secure system, without compromising with safety, performance or functionality.”

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 analogue 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 it suitable for automotive OEMs.

The series of four modules provide comprehensive band configurations, allowing the module to operate in the all markets of the world, throughout North America, EMEA, APAC/Brazil and China. u-blox TOBY-L4 LTE advanced modules will be featured at the TU-Automotive Detroit Conference and Expo, 7th to 8th June 2017, booth B77.
