Infineon SAB-C167CR-LM 16-Bit Microcontroller for Industrial Embedded Systems

The relentless drive for greater efficiency, reliability, and intelligence in industrial automation, motor control, and power conversion demands microcontrollers (MCUs) built to withstand challenging environments while delivering deterministic performance. The Infineon SAB-C167CR-LM stands as a quintessential solution, a robust 16-bit microcontroller architected from the ground up to meet the rigorous demands of industrial embedded systems.

At the heart of this MCU lies a high-performance 16-bit C167CS CPU core, capable of operating at clock frequencies up to 20 MHz. This core is engineered for efficient computation of complex real-time tasks, a common requirement in applications like sensor data processing, closed-loop control algorithms, and communication protocol handling. Its four-stage pipeline and integrated multiply/accumulate (MAC) unit significantly enhance its computational throughput, enabling it to execute instructions in a single clock cycle for superior performance.

Memory architecture is a critical strength of the SAB167CR-LM. It features a versatile memory controller supporting up to 16 MB of external address space for both program and data, alongside on-chip memory resources including ROM, RAM, and a unique Dual-Port RAM (DPRAM). This DPRAM is particularly valuable for efficient communication with peripheral units or in multi-processor systems, allowing for seamless data exchange without bus contention. This robust memory support is vital for storing large application code and managing substantial data sets in sophisticated industrial programs.

For industrial connectivity and control, the peripheral set is exceptionally comprehensive. The MCU integrates a sophisticated 16-channel Capture/Compare Unit (CAPCOM2) that is indispensable for generating and measuring complex PWM signals for precise motor control. Multiple serial interfaces, including high-speed synchronous ASC (Asynchronous Serial Channel) and SSC (Synchronous Serial Channel), provide flexible options for connecting to sensors, actuators, and industrial network modules like CAN (Controller Area Network). The inclusion of a CAN 2.0B controller is a standout feature, providing robust and reliable network connectivity essential for most industrial automation environments.

Beyond performance, the SAB-C167CR-LM is designed for resilience. Its operational temperature range and hardened design ensure stable functionality in the electrically noisy and thermally volatile conditions typical of factory floors. This focus on ruggedness and real-time capability makes it an ideal choice for a wide array of demanding applications, including industrial inverters, servo drives, PLCs (Programmable Logic Controllers), and automotive control systems.

ICGOOODFIND: The Infineon SAB-C167CR-LM remains a powerful and relevant 16-bit microcontroller that exemplifies the marriage of high computational performance, extensive peripheral integration, and industrial-grade robustness. Its dedicated features for motor control, coupled with robust communication interfaces like CAN, solidify its position as a trusted workhorse in the embedded design engineer's toolkit for demanding industrial applications.
