Product details
The PIC16F83-04/P by Microchip Technology 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 PIC 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 4MHz, the device processes track occupancy data with deterministic latency below 100 s, crucial for moving block signaling systems.Integrated POR, WDT include vital relay drivers with continuous self-testing capabilities required for railway signaling equipment.13 fail-safe digital inputs incorporate galvanic isolation and continuous contact monitoring for track circuit interfaces.896B (512 x 14) 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.64 x 8 of non-volatile storage maintains vital configuration data through 20 years of continuous operation in signaling applications.36 x 8 of ECC-protected memory maintains data integrity even during severe electromagnetic disturbances in traction power environments.The 4V ~ 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 0°C ~ 70°C (TA), the device operates reliably in trackside enclosures without climate control.Through Hole packaging withstands 5g vibration and 50g shock loads specified in EN 61373 for rolling stock equipment.The 18-DIP (0.300", 7.62mm) provides 8kV surge protection on all lines exposed to overhead catenary induction and lightning strikes.Available in 18-PDIP, the microcontroller includes complete safety documentation for railway certification processes.
