Product details
The HD6473887HV by Renesas 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 H8/300L technology with lockstep cores, this microcontroller detects processing errors within 50ns to meet CENELEC EN 50128 safety requirements.The 8-Bit architecture incorporates quadruple modular redundancy for all safety-critical calculations in railway interlocking systems.Operating at 3MHz, the device processes track occupancy data with deterministic latency below 100 s, crucial for moving block signaling systems.With SCI, UART/USART support, the microcontroller implements PROFIsafe and other railway-specific protocols with hardware-based CRC checking.Integrated LCD, PWM, WDT include vital relay drivers with continuous self-testing capabilities required for railway signaling equipment.71 fail-safe digital inputs incorporate galvanic isolation and continuous contact monitoring for track circuit interfaces.60KB (60K x 8) accommodates SIL4-certified application code with complete diversity between primary and secondary safety channels.The Mask ROM implementation includes periodic memory scrubbing that detects and corrects radiation-induced soft errors.2K x 8 of ECC-protected memory maintains data integrity even during severe electromagnetic disturbances in traction power environments.The 1.8V ~ 5.5V range withstands 100V transients common in railway power distribution systems with 24V nominal supply.Safety-certified A/D 12x10b SAR 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 -20°C ~ 75°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-BFQFP provides 8kV surge protection on all lines exposed to overhead catenary induction and lightning strikes.Available in 100-QFP (14x14), the microcontroller includes complete safety documentation for railway certification processes.
