TOBY-L4 Series - Supports LTE Cat 6 TDD, LTE Cat 6 FDD, UMTS and GSM connectivity

LTE Advanced (Cat. 6) modules with uCPU Linux application programming

The TOBY-L4 series supports LTE Cat 6 TDD, LTE Cat 6 FDD, UMTS and GSM connectivity in a compact LGA package. Developers can host their applications directly in the module in a configurable Linux OS, enabling customers to save the cost of an external CPU, memory and peripherals in order to optimize the total cost. Customer application development in a standard Linux/Yocto environment based on HW virtualization benefits from the flexible open source Linux community.

The extremely powerful embedded CPU has 19000 DMIPS, allowing the development of complex and demanding applications, such as Cat 6 Wi-Fi hot spotting and in-car telephony. With no processor bottleneck, the application can be scaled up as needed. The module comes with an extremely comprehensive set of HW interfaces (including RGMII/RMII for Ethernet and analog audio) so that applications do not need expensive external components, such as serial to Ethernet bridges or audio codecs.

With 3GPP Rel. 10 and LTE Cat 6 supporting carrier aggregation, which provides data throughput up to 300 Mbit/s, the modules are the perfect choice for applications requiring the highest data rates.

The -40 °C to +85 °C temperature range supports the establishment of an eCall at +95 °C for at least 2 minutes. Complemented by a set of state-of-the art security features, TOBY-L4 modules are the ideal product for the development of all kinds of automotive devices, such as smart antennas and in-dash telematics/infotainment devices.
