Infineon SAFC167CRLMHA: Technical Specifications and Application Overview
The Infineon SAFC167CRLMHA is a highly integrated, system-on-chip (SoC) microcontroller unit (MCU) from Infineon's comprehensive AUDO Future family. Based on a high-performance TriCore™ TC16xx 32-bit microcontroller architecture, this device is engineered to meet the demanding requirements of modern automotive and industrial applications, where reliability, real-time performance, and connectivity are paramount.
Technical Specifications
At its core, the SAFC167CRLMHA features a single TriCore CPU, delivering a powerful blend of a RISC processor's high efficiency, a microcontroller's real-time capability, and a DSP's computational power. The core operates at clock speeds of up to 80 MHz, providing the necessary processing muscle for complex algorithms and control tasks.
A standout feature of this MCU is its substantial embedded memory configuration. It is equipped with 1.25 MB of Flash memory for robust program storage and 76 KB of RAM for efficient data handling during runtime. This memory capacity is critical for supporting sophisticated software stacks and ensuring smooth operation without external memory in many cases.
The peripheral set is extensive and tailored for embedded control. Key components include:
A Micro Second Channel (MSC) controller, which is essential for handling complex PWM generation for motor control.
A 10-bit Analog-to-Digital Converter (ADC) with a modular and scalable architecture for precise acquisition of sensor data.
Multiple CAN (Controller Area Network) interfaces, including CAN FD, which are the backbone of automotive networking for reliable communication between electronic control units (ECUs).
ASC (Asynchronous/Synchronous Serial Channel) and SSC (Synchronous Serial Channel) modules, supporting standards like LIN, UART, and SPI for flexible connectivity to a wide array of sensors and peripherals.
Housed in a PG-LQFP-100 package, the device is designed for surface-mount technology, making it suitable for automated PCB assembly processes common in high-volume manufacturing.
