Infineon SAK-C167CR-LMHA+: A High-Performance 16-Bit Microcontroller for Embedded Automotive and Industrial Applications

The demand for robust, high-performance microcontrollers in automotive and industrial systems continues to grow, driven by the need for greater processing power, reliability, and integration. The Infineon SAK-C167CR-LMHA+ stands out as a premier 16-bit microcontroller designed specifically to meet the stringent requirements of these demanding environments. Combining a powerful CPU core with a rich set of peripherals, it serves as a cornerstone for complex embedded applications where performance and durability are non-negotiable.

At the heart of this microcontroller lies the high-performance C167CS 16-bit CPU core, capable of operating at clock speeds of up to 20 MHz. This core delivers an impressive 10 million instructions per second (MIPS), enabling it to handle computationally intensive tasks efficiently. Its four-stage pipeline and dedicated multiply/divide unit further accelerate processing, making it suitable for real-time control algorithms, data processing, and complex system management.

Memory resources are ample and strategically organized. The device features 2 KB of on-chip Dual-Port RAM (DPRAM) and 32 KB of on-chip Single-Port RAM (SPRAM), providing fast and flexible data storage. For program code, it integrates 256 KB of mask-programmable ROM, ensuring reliable firmware execution. This memory architecture is critical for applications requiring rapid access to data and code without external memory components, simplifying board design and enhancing system reliability.

A key strength of the SAK-C167CR-LMHA+ is its extensive and versatile peripheral set, engineered for direct interaction with the physical world. It includes a 16-channel 10-bit Analog-to-Digital Converter (ADC) with programmable conversion times, essential for reading sensors in automotive systems (e.g., engine control, temperature monitoring). For timing and control, it is equipped with two multi-functional General Purpose Timer Units (GPT1, GPT2) and a Capture/Compare Unit (CAPCOM2), which are vital for generating PWM signals for motor control or capturing sensor input timings.

Connectivity is another area of excellence. The controller includes a CAN (Controller Area Network) 2.0B module, a standard bus protocol in automotive networking for communication between electronic control units (ECUs). Additionally, it features on-board serial channels (ASC, SSC) for LIN bus, SPI, or I2C communications, providing flexible options for connecting to other sensors, actuators, or display modules within a network.

Designed for rugged operating conditions, the microcontroller operates over an ambient temperature range of -40°C to +85°C (extended to +125°C for junction temperature), making it perfectly suited for under-the-hood automotive applications or harsh industrial automation environments. Its resilience against electrical noise and extreme temperatures ensures long-term operational stability.

In summary, the Infineon SAK-C167CR-LMHA+ is a highly integrated solution that balances raw processing power with specialized peripherals. It empowers designers to build sophisticated, reliable, and efficient systems for the most challenging applications.
