Infineon CYT2B75CADQ0AZSGST: A 32-bit AURIX™ TC3x Microcontroller for Demanding Automotive and Industrial Applications
The relentless drive towards greater automation, electrification, and connectivity in the automotive and industrial sectors demands microcontrollers (MCUs) that deliver uncompromising performance, safety, and security. At the forefront of this technological evolution is the Infineon CURIX™ TC3x family, with the CYT2B75CADQ0AZSGST standing out as a premier solution engineered for the most challenging applications.
This 32-bit tri-core MCU is built on a high-performance architecture featuring three independent TriCore™ 1.6.2 P CPUs. This multi-core design is pivotal for handling complex tasks concurrently. It allows for functional separation where one core can be dedicated to real-time control loops, another to communication protocols, and a third to safety monitoring, thereby enhancing both performance and functional safety. With clock speeds reaching up to 300 MHz, the device provides the substantial computational horsepower required for advanced algorithms in electric vehicle inverters, advanced driver-assistance systems (ADAS), and sophisticated factory automation controllers.
A cornerstone of the AURIX™ TC3x series is its unmatched commitment to functional safety (FuSa). The CYT2B75CADQ0AZSGST is meticulously designed to comply with the stringent requirements of ISO 26262 (ASIL-D) for automotive and IEC 61508 (SIL-3) for industrial applications. This is achieved through a comprehensive suite of safety features, including hardware-based memory protection, redundant computing units, built-in self-test (BIST) capabilities, and a sophisticated Safety Unit. These integrated mechanisms proactively detect and manage potential errors, ensuring reliable operation in safety-critical systems where failure is not an option.
Complementing its safety credentials is a robust security architecture. As modern systems become increasingly connected, they are more vulnerable to cyber-attacks. This MCU addresses these threats head-on with a Hardware Security Module (HSM) containing a dedicated cryptographic core. It supports a wide range of encryption algorithms (AES, SHA, RSA, ECC) and provides secure key storage, enabling secure boot, secure communication (e.g., MACsec, IPsec), and protection against unauthorized access and intellectual property theft.
Furthermore, the device is packed with a rich set of peripherals tailored for its target markets. It includes high-precision Analog-to-Digital Converters (ADCs), timers for motor control (GPTA), and numerous communication interfaces such as CAN FD, Ethernet TSN, and FlexRay. These features make it an ideal single-chip controller for domain control, battery management systems (BMS), braking systems, and powerful PLCs.
ICGOOODFIND: The Infineon CYT2B75CADQ0AZSGST is far more than just a microcontroller; it is a comprehensive embedded safety and security platform. Its powerful tri-core processing, top-tier functional safety compliance, and advanced hardware security features make it an exceptional choice for developers building the next generation of reliable and secure automotive and industrial systems.
