Product details
The ST33HTPH2028AAF3 from STMicroelectronics revolutionizes Embedded - Microcontrollers for medical electronics, combining ultra-low noise performance with stringent safety certifications for life-critical applications.The SecurCore® SC300™ 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 33MHz 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 SPI interfaces incorporate medical-grade isolation up to 5kVrms, enabling direct connection to patient-connected sensors without external isolation barriers.The FLASH implementation features hardware-enforced read-only regions for critical code segments, preventing unauthorized modifications.The 1.8V, 3.3V range supports operation from medical-grade power supplies with <10 A patient leakage current in BF-rated applications.Rated for -40°C ~ 105°C (TA), the device operates reliably in sterilization cycles and extreme clinical environments.Surface Mount packaging uses biocompatible molding compounds that outgas <1 g/cm in vacuum environments, suitable for implantable applications.The 28-TSSOP (0.173", 4.40mm Width) format provides <1pF pin-to-pin capacitance, preventing signal crosstalk in high-density medical imaging front-end electronics.Available in 28-TSSOP, the microcontroller is manufactured in ISO 13485-certified facilities with full device history tracking.
