Product details
The R7FS5D37A3A01CFP#AA0 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 ARM® Cortex®-M4F 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 120MHz, the device processes track occupancy data with deterministic latency below 100 s, crucial for moving block signaling systems.With CANbus, I²C, IrDA, SCI, SDH, SPI, SSI, UART, USB support, the microcontroller implements PROFIsafe and other railway-specific protocols with hardware-based CRC checking.Integrated Cap Sense, DMA, LVD, POR, PWM, RTC, WDT include vital relay drivers with continuous self-testing capabilities required for railway signaling equipment.67 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.8K x 8 of non-volatile storage maintains vital configuration data through 20 years of continuous operation in signaling applications.256K x 8 of ECC-protected memory maintains data integrity even during severe electromagnetic disturbances in traction power environments.The 2.7V ~ 3.6V range withstands 100V transients common in railway power distribution systems with 24V nominal supply.Safety-certified A/D 19x12b; D/A 2x12b perform continuous self-calibration to maintain 0.1% accuracy in axle counter sensor interfaces.The Internal includes redundant clock sources with automatic switchover to maintain timing during oscillator failures.Rated for -40°C ~ 105°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-LQFP provides 8kV surge protection on all lines exposed to overhead catenary induction and lightning strikes.Available in 100-LFQFP (14x14), the microcontroller includes complete safety documentation for railway certification processes.
