Product details
The TT21100-44LQI33T from Infineon Technologies revolutionizes Embedded - Microcontrollers for medical electronics, combining ultra-low noise performance with stringent safety certifications for life-critical applications.The ARM® Cortex® architecture implements dual-core lockstep with cycle-accurate comparison, detecting faults within 10ns to meet IEC 62304 Class C requirements.A 32-Bit Single-Core processing width enables single-cycle execution of complex DSP filters for real-time biosignal processing in patient monitoring equipment.Operating at 500kHz with <10 V supply noise, the microcontroller maintains analog signal integrity for precision ECG front-ends with <0.5 Vp-p input-referred noise.The I²C, SPI interfaces incorporate medical-grade isolation up to 5kVrms, enabling direct connection to patient-connected sensors without external isolation barriers.With 33 channels supporting <1nA leakage current, the device can interface directly with high-impedance biopotential sensors without buffering.The 1.71V ~ 5.5V range supports operation from medical-grade power supplies with <10 A patient leakage current in BF-rated applications.Surface Mount packaging uses biocompatible molding compounds that outgas <1 g/cm in vacuum environments, suitable for implantable applications.The 44-UFQFN Exposed Pad format provides <1pF pin-to-pin capacitance, preventing signal crosstalk in high-density medical imaging front-end electronics.Available in 44-QFN (5x5), the microcontroller is manufactured in ISO 13485-certified facilities with full device history tracking.
