描述 Description

Devices from Telemaco2 family provide a cost effective microprocessor solution for automotive telematics applications based on a MIPS efficient ARM - Cortex R4 processor.
In addition, an ARM - Cortex M3 controller is dedicated to real-time processing tasks.
Telemaco2 devices come with a complete set of common interfaces (UART/I2S/I2C/USB/MMC) which make this family optimal for implementing a feature reach system as well as a cost effective solutions for automotive connectivity.
Telemaco2 devices can provide enough processing capability to handle positioning and wireless data management typically required in telematics use cases. Moreover, they can handle the control of the in-vehicle CAN bus thanks to the independent and secure Cortex-M3 subsystem running its dedicated real-time OS. With its flexible memory configuration, they allow implementing a variety of systems, starting from very low cost applications based on a real time OS and scaling up to demanding applications based on rich Linux OS.
