Infineon SAF-C164CI-8EMDA: A Robust 16-Bit Microcontroller for Demanding Automotive Systems

The evolution of modern automotive systems hinges on the performance and reliability of their embedded electronic control units (ECUs). At the heart of many critical applications lies the Infineon SAF-C164CI-8EMDA, a high-performance 16-bit microcontroller engineered specifically to meet the stringent requirements of the automotive industry. This powerful MCU is designed to deliver the computational muscle, connectivity, and resilience necessary for next-generation vehicle systems.

Built upon the proven C166SV2 architecture, this microcontroller operates at speeds of up to 40 MHz, providing the substantial processing power required for complex real-time control algorithms. This capability is essential for managing sophisticated functions in engine control, transmission systems, braking, and steering. Its 16-bit core efficiently handles high-speed calculations, ensuring precise and timely responses to sensor inputs and system demands.

A standout feature of the SAF-C164CI-8EMDA is its robust set of on-chip peripherals. It includes a highly flexible Multi-Functional General Purpose Timer Unit (GPT12E), multiple serial interfaces (including CAN, ASC, and SSC), and a sophisticated 16-channel A/D converter. This high level of integration simplifies system design, reduces component count, and enhances overall reliability by minimizing external connections. The integrated CAN (Controller Area Network) interface is particularly crucial, serving as the backbone for communication between various ECUs within a vehicle's network.

Recognizing the harsh operating environments of automotive applications, Infineon has designed this MCU with a primary focus on functional safety and reliability. It operates across a wide temperature range and is built to withstand the electrical noise and voltage transients typical in automotive environments. These characteristics make it an ideal choice for safety-critical systems where failure is not an option.

Furthermore, the device offers a substantial 256 KB of on-chip Flash memory for program storage and a generous 12 KB of RAM for data handling. This ample memory space supports feature-rich software and complex data processing tasks, providing designers with the headroom needed for application growth and future updates.
