Product details
The ST33HTPH2032AAF3 by STMicroelectronics pioneers ultra-reliable Embedded - Microcontrollers for railway signaling systems. Its fail-safe architecture and SIL4 certification make it the preferred choice for vital train control applications.Featuring SecurCore® SC300™ technology with lockstep cores, this microcontroller detects processing errors within 50ns to meet CENELEC EN 50128 safety requirements.The 32-Bit Single-Core architecture incorporates quadruple modular redundancy for all safety-critical calculations in railway interlocking systems.Operating at 33MHz, the device processes track occupancy data with deterministic latency below 100 s, crucial for moving block signaling systems.With SPI support, the microcontroller implements PROFIsafe and other railway-specific protocols with hardware-based CRC checking.The FLASH implementation includes periodic memory scrubbing that detects and corrects radiation-induced soft errors.The 1.8V, 3.3V range withstands 100V transients common in railway power distribution systems with 24V nominal supply.Rated for -40°C ~ 105°C (TA), the device operates reliably in trackside enclosures without climate control.Surface Mount packaging withstands 5g vibration and 50g shock loads specified in EN 61373 for rolling stock equipment.The 32-VFQFN Exposed Pad provides 8kV surge protection on all lines exposed to overhead catenary induction and lightning strikes.Available in 32-VFQFPN (5x5), the microcontroller includes complete safety documentation for railway certification processes.
