Product details
The K32L2B21VFT0A by NXP USA Inc. 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 ARM® Cortex®-M0+ technology with lockstep cores, this microcontroller detects processing errors within 50ns to meet CENELEC EN 50128 safety requirements.The 32-Bit Single-Core architecture incorporates quadruple modular redundancy for all safety-critical calculations in railway interlocking systems.Operating at 48MHz, the device processes track occupancy data with deterministic latency below 100 s, crucial for moving block signaling systems.With FlexIO, I²C, SPI, TSI, UART/USART, USB support, the microcontroller implements PROFIsafe and other railway-specific protocols with hardware-based CRC checking.Integrated DMA, LCD, PWM, WDT include vital relay drivers with continuous self-testing capabilities required for railway signaling equipment.128KB (128K x 8) 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.32K x 8 of ECC-protected memory maintains data integrity even during severe electromagnetic disturbances in traction power environments.The 1.2V 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.Surface Mount packaging withstands 5g vibration and 50g shock loads specified in EN 61373 for rolling stock equipment.The 48-UFQFN Exposed Pad provides 8kV surge protection on all lines exposed to overhead catenary induction and lightning strikes.Available in 48-QFN (7x7), the microcontroller includes complete safety documentation for railway certification processes.
