Product details
The IA186ESPQF100IR03 by Analog Devices 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.The 8/16-Bit architecture incorporates quadruple modular redundancy for all safety-critical calculations in railway interlocking systems.Operating at 40MHz, the device processes track occupancy data with deterministic latency below 100 s, crucial for moving block signaling systems.With EBI/EMI, UART/USART support, the microcontroller implements PROFIsafe and other railway-specific protocols with hardware-based CRC checking.Integrated DMA, PWM, WDT include vital relay drivers with continuous self-testing capabilities required for railway signaling equipment.32 fail-safe digital inputs incorporate galvanic isolation and continuous contact monitoring for track circuit interfaces.The ROMless implementation includes periodic memory scrubbing that detects and corrects radiation-induced soft errors.The 4.5V ~ 5.5V range withstands 100V transients common in railway power distribution systems with 24V nominal supply.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 100-BQFP provides 8kV surge protection on all lines exposed to overhead catenary induction and lightning strikes.Available in 100-PQFP (20x14), the microcontroller includes complete safety documentation for railway certification processes.
