Product details
The MIMXRT1172AVM8A by NXP USA Inc. 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®-M7 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 800MHz, the device processes track occupancy data with deterministic latency below 100 s, crucial for moving block signaling systems.With CANbus, EBI/EMI, Ethernet, I²C, MMC/SD/SDIO, SAI, SPDIF, 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, POR, PWM, WDT include vital relay drivers with continuous self-testing capabilities required for railway signaling equipment.The External Program Memory implementation includes periodic memory scrubbing that detects and corrects radiation-induced soft errors.2M x 8 of ECC-protected memory maintains data integrity even during severe electromagnetic disturbances in traction power environments.Safety-certified A/D 2x12b; D/A 1x12b 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 ~ 125°C (TJ), 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 289-LFBGA provides 8kV surge protection on all lines exposed to overhead catenary induction and lightning strikes.Available in 289-MAPBGA (14x14), the microcontroller includes complete safety documentation for railway certification processes.
