Product details
The MC68334GCEH20 from Freescale Semiconductor revolutionizes Embedded - Microcontrollers for medical electronics, combining ultra-low noise performance with stringent safety certifications for life-critical applications.The CPU32 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 20MHz 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 EBI/EMI, UART/USART interfaces incorporate medical-grade isolation up to 5kVrms, enabling direct connection to patient-connected sensors without external isolation barriers.With 47 channels supporting <1nA leakage current, the device can interface directly with high-impedance biopotential sensors without buffering.The ROMless implementation features hardware-enforced read-only regions for critical code segments, preventing unauthorized modifications.1K x 8 of ECC-protected memory prevents silent data corruption in drug delivery systems where single-bit errors could have life-threatening consequences.The 3V ~ 5.5V range supports operation from medical-grade power supplies with <10 A patient leakage current in BF-rated applications.Precision A/D 8x8/10b achieve 20-bit effective resolution through oversampling and chopper stabilization, enabling direct digitization of microvolt-level biosignals.The External design maintains <1ppm frequency stability for accurate timing of therapeutic delivery systems where dosing accuracy is critical.Rated for -40°C ~ 85°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 132-BQFP Bumpered format provides <1pF pin-to-pin capacitance, preventing signal crosstalk in high-density medical imaging front-end electronics.Available in 132-PQFP (24.13x24.13), the microcontroller is manufactured in ISO 13485-certified facilities with full device history tracking.
