Product details
The MB89821PMC1-G-123-BND-R by Infineon Technologies 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 F²MC-8L 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 5MHz, the device processes track occupancy data with deterministic latency below 100 s, crucial for moving block signaling systems.With Serial I/O, UART/USART support, the microcontroller implements PROFIsafe and other railway-specific protocols with hardware-based CRC checking.Integrated LCD, POR, PWM, WDT include vital relay drivers with continuous self-testing capabilities required for railway signaling equipment.28 fail-safe digital inputs incorporate galvanic isolation and continuous contact monitoring for track circuit interfaces.4KB (4K 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.128 x 8 of ECC-protected memory maintains data integrity even during severe electromagnetic disturbances in traction power environments.The 2.2V ~ 6V range withstands 100V transients common in railway power distribution systems with 24V nominal supply.The External includes redundant clock sources with automatic switchover to maintain timing during oscillator failures.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 80-LQFP provides 8kV surge protection on all lines exposed to overhead catenary induction and lightning strikes.Available in 80-PQFP (14x14), the microcontroller includes complete safety documentation for railway certification processes.
