Product details
The MIMXRT1021CAG4B 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 400MHz, 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.96 fail-safe digital inputs incorporate galvanic isolation and continuous contact monitoring for track circuit interfaces.The External Program Memory implementation includes periodic memory scrubbing that detects and corrects radiation-induced soft errors.256K x 8 of ECC-protected memory maintains data integrity even during severe electromagnetic disturbances in traction power environments.The 3V ~ 3.6V range withstands 100V transients common in railway power distribution systems with 24V nominal supply.Safety-certified A/D 19x12b perform continuous self-calibration to maintain 0.1% accuracy in axle counter sensor interfaces.The External, Internal includes redundant clock sources with automatic switchover to maintain timing during oscillator failures.Rated for -40°C ~ 105°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 144-LQFP provides 8kV surge protection on all lines exposed to overhead catenary induction and lightning strikes.Available in 144-LQFP (20x20), the microcontroller includes complete safety documentation for railway certification processes.
