1. Introduction “Increase in electronic components/units installed in automobiles and technological trends”
Currently, in the automobile industry, the number of electronic units installed in cars continues to increase year by year due to the increasing electrification of drive trains and the need for more sophisticated advanced driver assistance systems (ADAS). I am.
In addition, security requirements and power consumption requirements are increasing day by day, and this is partly due to the introduction of autonomous driving (AD) functions. autonomous driving is divided into five levels, levels 1 to 5. Especially after level 3, the driver does not need to constantly monitor the system's operating status or the surrounding environment, and in order to achieve this, it is necessary to provide only driving support. It is necessary to evolve from a system that performs driving actions autonomously. In order to realize such a system, it is necessary to consider such things as integration of a large amount of sensor data, deep learning, cloud, infrastructure, cooperation between vehicles, and connectivity with network services that communicate with other vehicles and infrastructure. This is essential, and for this reason, requirements for ensuring secure communication and power consumption are increasing for each domain unit.
Furthermore, there are changes in unit functions that improve the livability and comfort of not only the front seats but also the rear seats, as well as the specifications of conventional functions for the so-called body domain such as doors, windows, sunroofs, seat control, etc. As a result, the number of units and systems has increased and become more complex, leading to a fundamental review of the electronic/electrical architecture (E/E architecture) of automobiles.
The TRAVEO™ T2G-B introduced here is one of the MCU product families provided by Infineon in response to the above-mentioned trends.

2. TRAVEO™ T2G-B Product Overview
feature
TRAVEO™ T2G-B is a general-purpose automotive microcontroller that uses Arm® Cortex®-M7F/M4F as its main core and operates at a maximum operating frequency of 350MHz. Evita Full is equipped with an Arm® Cortex®-M0+ core as standard in all products to achieve high security functions, and in addition to enabling secure communication, it also supports eSHE and HSM as a device. We can accommodate you.
It also has the FOTA (Firmware Over The Air) function, which has become a requirement for connected cars in recent years, and supports a dual bank memory configuration that allows programming while an application program is running. It is a product that contributes to meeting the strict demands and challenges of automotive applications, including a built-in flash, ISO26262 ASIL-B compliance, and operation at ambient temperatures up to 125°C.
TRAVEO™ T2G-B Main Features
Product lineup
The product family ranges from low to high end to provide scalability and pin compatibility.
This allows for easy upward / downward compatibility when, for example, there is an excess or shortage of resources during the customer evaluation phase.
product portfolio
Example of use
Targeting a wide range of units and applications, it supports a wide range of protocols CAN-FD, I2S/TDM, CXPI, Ethernet, FlexRay,such as in addition to standard peripherals such as CAN, LIN, SPI, I2C, and UART. This contributes to realizing the expected specifications with a single chip. In addition, eMMC, SMIF, etc. for external memory access are also available.
It also has a built-in 12-bit successive approximation AD converter with up to 96 channels, which allows not only signal acquisition from peripheral sensors but also actuator control in combination with high-performance PWM (TCPWM).
Here we present an example of how Infineon 's TRAVEO™ T2G-B controller can be used in a body control unit.
