Product details
The STM32F423MHY6TR 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 ARM® Cortex®-M4 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 100MHz, the device processes track occupancy data with deterministic latency below 100 s, crucial for moving block signaling systems.With CANbus, I²C, IrDA, LINbus, MMC/SD, QSPI, SAI, SPI, UART/USART, USB OTG support, the microcontroller implements PROFIsafe and other railway-specific protocols with hardware-based CRC checking.Integrated Brown-out Detect/Reset, DMA, I²S, LCD, POR, PWM, WDT include vital relay drivers with continuous self-testing capabilities required for railway signaling equipment.60 fail-safe digital inputs incorporate galvanic isolation and continuous contact monitoring for track circuit interfaces.1.5MB (1.5M x 8) accommodates SIL4-certified application code with complete diversity between primary and secondary safety channels.The FLASH implementation includes periodic memory scrubbing that detects and corrects radiation-induced soft errors.320K x 8 of ECC-protected memory maintains data integrity even during severe electromagnetic disturbances in traction power environments.The 1.7V ~ 3.6V range withstands 100V transients common in railway power distribution systems with 24V nominal supply.Safety-certified A/D 16x12b; D/A 2x12b perform continuous self-calibration to maintain 0.1% accuracy in axle counter sensor interfaces.The Internal includes redundant clock sources with automatic switchover to maintain timing during oscillator failures.Rated for -40°C ~ 85°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 81-UFBGA, WLCSP provides 8kV surge protection on all lines exposed to overhead catenary induction and lightning strikes.Available in 81-WLCSP (4.04x3.95), the microcontroller includes complete safety documentation for railway certification processes.
