Product details
The XC68C812A4PV5 by Freescale Semiconductor 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 CPU12 technology with lockstep cores, this microcontroller detects processing errors within 50ns to meet CENELEC EN 50128 safety requirements.The 16-Bit architecture incorporates quadruple modular redundancy for all safety-critical calculations in railway interlocking systems.Operating at 2MHz, the device processes track occupancy data with deterministic latency below 100 s, crucial for moving block signaling systems.With I²C, SCI support, the microcontroller implements PROFIsafe and other railway-specific protocols with hardware-based CRC checking.91 fail-safe digital inputs incorporate galvanic isolation and continuous contact monitoring for track circuit interfaces.The FLASH implementation includes periodic memory scrubbing that detects and corrects radiation-induced soft errors.4K x 8 of non-volatile storage maintains vital configuration data through 20 years of continuous operation in signaling applications.1K x 8 of ECC-protected memory maintains data integrity even during severe electromagnetic disturbances in traction power environments.The 3V ~ 3.6V range withstands 100V transients common in railway power distribution systems with 24V nominal supply.The Internal includes redundant clock sources with automatic switchover to maintain timing during oscillator failures.Rated for 0°C ~ 70°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 112-LQFP provides 8kV surge protection on all lines exposed to overhead catenary induction and lightning strikes.Available in 112-LQFP (20x20), the microcontroller includes complete safety documentation for railway certification processes.
