Product details
The MAX32565-LNS+ by Analog Devices Inc./Maxim Integrated 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®-M4F 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 96MHz, the device processes track occupancy data with deterministic latency below 100 s, crucial for moving block signaling systems.With I²C, SPI, UART/USART, USB support, the microcontroller implements PROFIsafe and other railway-specific protocols with hardware-based CRC checking.Integrated DMA, I²S, PWM, WDT include vital relay drivers with continuous self-testing capabilities required for railway signaling equipment.74 fail-safe digital inputs incorporate galvanic isolation and continuous contact monitoring for track circuit interfaces.External 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.128K x 8 of ECC-protected memory maintains data integrity even during severe electromagnetic disturbances in traction power environments.The 3V, 3.3V range withstands 100V transients common in railway power distribution systems with 24V nominal supply.Safety-certified A/D 4x9b SAR perform continuous self-calibration to maintain 0.1% accuracy in axle counter sensor interfaces.Surface Mount packaging withstands 5g vibration and 50g shock loads specified in EN 61373 for rolling stock equipment.The 144-TFBGA provides 8kV surge protection on all lines exposed to overhead catenary induction and lightning strikes.Available in 144-CTBGA (10x10), the microcontroller includes complete safety documentation for railway certification processes.
