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

The evolution of automotive electronics demands microcontrollers that combine computational power, reliability, and specialized functionality to meet stringent industry standards. The Infineon SAF-C167CR-LM-HM+ stands out as a high-performance 16-bit microcontroller engineered specifically for demanding automotive applications, offering a robust blend of processing capability, integrated peripherals, and resilience in harsh operating environments.

At the core of this microcontroller is a powerful 16-bit C167CR CPU core, capable of operating at clock frequencies up to 20 MHz. This provides the necessary computational throughput for complex real-time control tasks, which are ubiquitous in modern vehicles. The architecture is optimized for high-speed execution of digital signal processing (DSP) instructions, making it exceptionally well-suited for applications such as engine management, transmission control, and advanced braking systems where rapid data processing is critical.

A key strength of the SAF-C167CR-LM-HA+ lies in its highly integrated design. It features a comprehensive set of on-chip peripherals that reduce system complexity, lower overall component count, and enhance reliability. These include:

A 10-channel 10-bit Analog-to-Digital Converter (ADC) for precise acquisition of sensor data from throttle position, temperature, pressure, and other analog sources.

Two Capture/Compare Units (CAPCOM2 and CAPCOM6) and multiple general-purpose timers, which are essential for generating and measuring precise PWM signals to control actuators, valves, and motors.

A sophisticated CAN (Controller Area Network) module (ASCAN) that ensures seamless and robust communication within the vehicle's network, adhering to the automotive CAN standard 2.0B.

On-chip memory resources, including ROM, RAM, and EEPROM, provide ample space for program code, data storage, and calibration values, crucial for firmware flexibility and functionality.

Designed with the rigors of the automotive world in mind, the SAF-C167CR-LM-HA+ is built to operate reliably under extreme conditions. It is qualified for an extended temperature range (-40°C to +125°C or higher), ensuring performance stability whether in a freezing cold start or under the hood in peak summer heat. Its construction is inherently robust against electrical transients and electromagnetic interference (EMI), common challenges in the automotive electrical environment. This resilience makes it a cornerstone for safety-critical systems where failure is not an option.
