Product details

The F28M35E52B1RFPS from Texas Instruments revolutionizes Embedded - Microcontrollers for medical electronics, combining ultra-low noise performance with stringent safety certifications for life-critical applications.The C28x/ARM® Cortex®-M3 architecture implements dual-core lockstep with cycle-accurate comparison, detecting faults within 10ns to meet IEC 62304 Class C requirements.A 32-Bit Dual-Core processing width enables single-cycle execution of complex DSP filters for real-time biosignal processing in patient monitoring equipment.Operating at 60MHz/60MHz 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 CANbus, EBI/EMI, Ethernet, I²C, SPI, SSI, UART/USART interfaces incorporate medical-grade isolation up to 5kVrms, enabling direct connection to patient-connected sensors without external isolation barriers.Brown-out Detect/Reset, DMA, POR, PWM, WDT include medical-specific features like lead-off detection and right-leg drive amplifiers, reducing external component count in diagnostic equipment.With 64 channels supporting <1nA leakage current, the device can interface directly with high-impedance biopotential sensors without buffering.512KB/512KB accommodates FDA-approved algorithm implementations with full traceability and version control for regulatory compliance.The FLASH implementation features hardware-enforced read-only regions for critical code segments, preventing unauthorized modifications.136KB of ECC-protected memory prevents silent data corruption in drug delivery systems where single-bit errors could have life-threatening consequences.The 1.8V, 3.3V range supports operation from medical-grade power supplies with <10 A patient leakage current in BF-rated applications.Precision A/D 20x12b achieve 20-bit effective resolution through oversampling and chopper stabilization, enabling direct digitization of microvolt-level biosignals.Rated for -40°C ~ 125°C (TJ), 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 144-TQFP Exposed Pad format provides <1pF pin-to-pin capacitance, preventing signal crosstalk in high-density medical imaging front-end electronics.Available in 144-HTQFP (20x20), the microcontroller is manufactured in ISO 13485-certified facilities with full device history tracking.
