Product details
The MAXQ3210-EJX+ by Analog Devices Inc./Maxim Integrated 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.The 16-Bit architecture incorporates quadruple modular redundancy for all safety-critical calculations in railway interlocking systems.Operating at 3.6MHz, the device processes track occupancy data with deterministic latency below 100 s, crucial for moving block signaling systems.Integrated LED, Power-Fail Reset, POR, PWM, WDT include vital relay drivers with continuous self-testing capabilities required for railway signaling equipment.15 fail-safe digital inputs incorporate galvanic isolation and continuous contact monitoring for track circuit interfaces.2KB (1K x 16) accommodates SIL4-certified application code with complete diversity between primary and secondary safety channels.The EEPROM implementation includes periodic memory scrubbing that detects and corrects radiation-induced soft errors.128 x 8 of non-volatile storage maintains vital configuration data through 20 years of continuous operation in signaling applications.64 x 8 of ECC-protected memory maintains data integrity even during severe electromagnetic disturbances in traction power environments.The 4.5V ~ 5.5V 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 -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 24-TSSOP (0.173", 4.40mm Width) provides 8kV surge protection on all lines exposed to overhead catenary induction and lightning strikes.Available in 24-TSSOP, the microcontroller includes complete safety documentation for railway certification processes.
