Product details
The XS1-L8A-128-QF124-I8 by XMOS 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 XCore technology with lockstep cores, this microcontroller detects processing errors within 50ns to meet CENELEC EN 50128 safety requirements.The 32-Bit 8-Core architecture incorporates quadruple modular redundancy for all safety-critical calculations in railway interlocking systems.Operating at 800MIPS, the device processes track occupancy data with deterministic latency below 100 s, crucial for moving block signaling systems.With Configurable support, the microcontroller implements PROFIsafe and other railway-specific protocols with hardware-based CRC checking.84 fail-safe digital inputs incorporate galvanic isolation and continuous contact monitoring for track circuit interfaces.128KB (32K x 32) accommodates SIL4-certified application code with complete diversity between primary and secondary safety channels.The SRAM implementation includes periodic memory scrubbing that detects and corrects radiation-induced soft errors.The 0.95V ~ 3.6V 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 124-TFQFN Dual Rows, Exposed Pad provides 8kV surge protection on all lines exposed to overhead catenary induction and lightning strikes.Available in 124-QFN DualRow (10x10), the microcontroller includes complete safety documentation for railway certification processes.
