Product details
The TMP19A43FDXBG by Toshiba Semiconductor and Storage 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 TX19A technology with lockstep cores, this microcontroller detects processing errors within 50ns to meet CENELEC EN 50128 safety requirements.The 16/32-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, I²C, UART/USART support, the microcontroller implements PROFIsafe and other railway-specific protocols with hardware-based CRC checking.Integrated DMA, WDT include vital relay drivers with continuous self-testing capabilities required for railway signaling equipment.143 fail-safe digital inputs incorporate galvanic isolation and continuous contact monitoring for track circuit interfaces.512KB (512K x 8) 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.24K x 8 of ECC-protected memory maintains data integrity even during severe electromagnetic disturbances in traction power environments.The 1.35V ~ 3.6V range withstands 100V transients common in railway power distribution systems with 24V nominal supply.Safety-certified A/D 16x10b; D/A 2x8b perform continuous self-calibration to maintain 0.1% accuracy in axle counter sensor interfaces.The External includes redundant clock sources with automatic switchover to maintain timing during oscillator failures.Rated for -20°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 193-FBGA provides 8kV surge protection on all lines exposed to overhead catenary induction and lightning strikes.
