Product details
The UPD703103AGJ-UEN-A by Renesas Electronics America 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 V850E1 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 50MHz, the device processes track occupancy data with deterministic latency below 100 s, crucial for moving block signaling systems.The ROMless implementation includes periodic memory scrubbing that detects and corrects radiation-induced soft errors.4K x 8 of ECC-protected memory maintains data integrity even during severe electromagnetic disturbances in traction power environments.Safety-certified A/D 8x10b perform continuous self-calibration to maintain 0.1% accuracy in axle counter sensor interfaces.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 144-LQFP provides 8kV surge protection on all lines exposed to overhead catenary induction and lightning strikes.Available in 144-FLQFP (20x20), the microcontroller includes complete safety documentation for railway certification processes.
