Infineon TLE7810G: A Low-Power 8-Bit SBC for Automotive and Industrial Applications

The demand for highly integrated, robust, and power-efficient control solutions is paramount in the automotive and industrial sectors. Addressing this need, Infineon Technologies has developed the TLE7810G, a sophisticated 8-bit Single-Bit Controller (SBC) that combines critical functionalities into a single, compact package. This device is engineered to serve as a central hub for managing power, communication, and control in a wide array of demanding applications.

At its core, the TLE7810G integrates an enhanced 8-bit microcontroller based on a powerful 8051 architecture. This core is complemented by a rich set of peripheral functions, making it far more than just a simple microcontroller. A key feature is its integrated LIN (Local Interconnect Network) transceiver, which is fully compliant with the LIN 2.x and SAE J2602 standards. This allows the TLE7810G to act as a LIN slave node, handling communication and commands from a master node within a vehicle network, or even as a standalone LIN master itself.

Beyond communication, the SBC excels in power management. It incorporates a voltage regulator that supplies power to the internal microcontroller and can also provide a stable output for external components. This is crucial for simplifying system design and reducing the total component count. Furthermore, its ultra-low power consumption in sleep modes is a standout characteristic. The device can draw as little as 10 µA, making it ideal for applications where quiescent current is a critical design parameter, such as in always-on automotive modules (e.g., seat control, sensor nodes) or battery-powered industrial sensors.

For system robustness, the TLE7810G is built to withstand the harsh environments typical of its target applications. It features high ESD protection and is designed to be resistant to transients and EMI. Its operational temperature range meets the stringent requirements for automotive electronics, ensuring reliable performance from -40°C to 150°C.

Typical applications highlight its versatility:

Automotive: Body control modules (e.g., window lifters, sunroof control, seat modules), sensor interfaces, and smart switches.

Industrial: Actuator control, building automation nodes, and low-power sensor hubs.
