Texas Instruments F29H85x Real-Time Microcontrollers
Texas Instruments F29H85x Real-Time Microcontrollers are designed to help engineers achieve more intelligent and secure processing in industrial and automotive applications. The F29H85x series is built on TI's 64-bit C29 digital signal processor core and includes an advanced architecture with integrated security and safety features. These microcontrollers provide comprehensive diagnostics, error-checking mechanisms, and cybersecurity capabilities, with a fully isolated hardware security module that protects systems from cyber threats and unauthorized access. The MCUs are engineered to comply with the International Organization for Standardization 26262 and International Electrotechnical Commission 61508 automotive and industrial safety standards, with levels up to ASIL D and SIL 3.
Texas Instruments F29H85x MCUs are part of the C2000™ real-time microcontroller family of scalable, ultra-low latency devices offering efficiency in power electronics, including but not limited to high switching frequencies, high power density, and supporting the use of GaN and SiC technologies. Applications include automated sorting equipment, industrial AC-DC, three-phase uninterruptible power supplies (UPS), medium- and short-range radar, a variety of inverters, and electric vehicle (EV) and hybrid EV (HEV) DC/DC converters.
