This MCU combines robust processing power with a rich set of peripherals, making it an ideal solution for a wide array of vehicle systems.

A cornerstone of its architecture is the powerful 16-bit C166SV2 core, capable of operating at frequencies up to 40 MHz. This provides the substantial computational throughput required for complex real-time control algorithms. The microcontroller is further enhanced by a 5-stage pipeline and a multiplication/division unit (MDU), which significantly accelerate mathematical operations common in signal processing and control tasks.

Memory resources are ample for mid-range applications, featuring 128 KB of on-chip Flash memory and 8 KB of on-chip RAM. This integrated memory supports robust program storage and efficient data handling, which is critical for ensuring reliable performance in the challenging automotive environment.

The peripheral set is where the SAK-XC164CM-16F20F truly excels for automotive applications. It includes:

Two powerful Capture/Compare Units (CCU6): These are essential for generating and measuring precise PWM signals, which are the lifeblood of controlling brushless DC (BLDC) motors in applications like electric power steering (EPS), engine cooling fans, and pumps.

A 10-bit Analog-to-Digital Converter (ADC): With a fast conversion time and multiple channels, it is perfectly suited for reading a multitude of sensors throughout a vehicle, from throttle position to temperature sensors.

CAN (Controller Area Network) Interface (MultiCAN): This is a non-negotiable feature for modern automotive design. It allows the microcontroller to communicate reliably with other electronic control units (ECUs) over the vehicle's standard CAN bus network.

On-Chip Oscillator and PLL: These contribute to a reduced bill of materials and increased reliability by minimizing the need for external components.

These features directly translate into critical automotive applications. The SAK-XC164CM-16F20F is a prime candidate for body electronics modules, such as power window and seat control units. Its real-time capabilities and motor control peripherals make it a perfect fit for sensorless BLDC motor control in EPS systems. Furthermore, it is widely used in engine management systems for controlling auxiliary components, fuel pumps, and in various pump and fan control modules under the hood.

ICGOOODFIND: The Infineon SAK-XC164CM-16F20F stands out as a highly integrated and reliable solution for automotive designers. Its blend of a proven 16-bit core, dedicated motor control peripherals, and essential automotive communication interfaces like CAN makes it a workhorse for a diverse range of in-vehicle applications, prioritizing performance, safety, and cost-effectiveness.
