Infineon SAF-C167CR-LM-HA 16-Bit Microcontroller for High-Reliability Automotive Applications

The automotive industry’s increasing reliance on electronic control systems demands microcontrollers that deliver uncompromising performance, durability, and safety. The Infineon SAF-C167CR-LM-HA stands out as a premier 16-bit microcontroller engineered specifically for high-reliability automotive applications, meeting the stringent requirements of systems where failure is not an option.

Built around a high-performance C167CR 16-bit CPU core, this microcontroller operates at clock frequencies up to 20 MHz, providing the computational muscle needed for complex real-time processing. Its robust architecture is designed for extreme automotive environments, capable of operating within a wide temperature range and resistant to electrical noise common in vehicles.

A key strength of the SAF-C167CR-LM-HA lies in its highly integrated peripheral set. It features a powerful Micro Second Channel (MSC), which enables sophisticated PWM generation for precise motor control—essential for electric power steering (EPS), engine management, and braking systems. The inclusion of a 10-bit Analog-to-Digital Converter (ADC) with a minimum conversion time of 7.8 µs allows for rapid and accurate sampling of sensor data from across the vehicle.

Reliability and functional safety are paramount in its design. The microcontroller incorporates advanced features such as a built-in Watchdog Timer and a Oscillator Watchdog to detect and react to hardware and software faults. Its enhanced memory protection unit safeguards critical data, ensuring system integrity. Furthermore, its design and manufacturing process adhere to automotive-grade quality standards (AEC-Q100), guaranteeing long-term performance under the hood.

Typical applications that benefit from its capabilities include:

Powertrain systems: Engine control units (ECUs) and transmission control.

Chassis and safety systems: Anti-lock braking systems (ABS) and stability control.

Body electronics: Advanced lighting control and comfort systems.

ICGOODFIND: The Infineon SAF-C167CR-LM-HA is a testament to embedded design for harsh environments. It successfully balances raw processing power with a rich suite of integrated peripherals, all while being hardened for automotive-grade reliability. For designers developing critical vehicle systems, this MCU offers a trusted, high-performance solution that prioritizes functional safety and durability above all.
