   • CRC engine (VCRC) and 10 hardware breakpoints enhance reliability and debugging capabilities
2. Memory & Storage
   • 128KB Flash (ECC-protected) and 24KB RAM (parity/ECC-protected) for code storage and data processing
   • Dual-zone security with encrypted flash programming for intellectual property protection
3. Analog & Control Peripherals
   • 14 Enhanced PWM (ePWM) channels with 150ps resolution for precise control of power stages (e.g., three-phase inverters, LLC converters) .
   • Two 12-bit ADCs (3.45 MSPS) with 4 post-processing blocks (PPB) for real-time signal conditioning .
   • Three Enhanced Capture (eCAP) modules and two Quadrature Encoder Pulse (eQEP) modules for motor feedback and motion control .
   • Configurable Logic Block (CLB) enables FPGA-like custom logic for advanced control algorithms
4. Communication Interfaces
   • PMBus, CAN, LIN, SPI, I2C, and UART for connectivity with power management ICs, sensors, and host systems
   • Fast Serial Interface (FSI) supporting 200 Mbps for high-speed data transfer across isolation boundaries .
5. Thermal & Safety Features
   • -40°C to 125°C operating temperature range (suffix "S") with AEC-Q100 qualification for automotive applications (suffix "Q")
   • Hardware Built-in Self-Test (HWBIST) and Memory Power-On Self-Test (MPOST) for functional safety compliance (ISO 26262, IEC 61508) .
