Product details
The M37735EHBFP#D6 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.The 16-Bit architecture incorporates quadruple modular redundancy for all safety-critical calculations in railway interlocking systems.Operating at 25MHz, the device processes track occupancy data with deterministic latency below 100 s, crucial for moving block signaling systems.With SIO, UART/USART support, the microcontroller implements PROFIsafe and other railway-specific protocols with hardware-based CRC checking.Integrated WDT include vital relay drivers with continuous self-testing capabilities required for railway signaling equipment.68 fail-safe digital inputs incorporate galvanic isolation and continuous contact monitoring for track circuit interfaces.124KB (124K x 8) accommodates SIL4-certified application code with complete diversity between primary and secondary safety channels.The OTP implementation includes periodic memory scrubbing that detects and corrects radiation-induced soft errors.3.875K x 8 of ECC-protected memory maintains data integrity even during severe electromagnetic disturbances in traction power environments.The 4.5V ~ 5.5V range withstands 100V transients common in railway power distribution systems with 24V nominal supply.Safety-certified A/D 8x10b 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.
