• Flexible Digital Peripherals：
  Provides enhanced UART, SMBus™, and SPI™ interfaces, four 16-bit timers, and a programmable counter array (PCA) with capture/compare modules and watchdog function, meeting multi-device communication and real-time control needs.
• Low-Power Design：
  Typical operating current of 5.8 mA@25 MHz, standby mode current as low as 0.1 µA, supporting Idle and Stop modes, ideal for battery-powered devices and energy-efficient applications.
• On-Chip Debug and Storage：
  Built-in full-speed non-intrusive debug circuitry eliminates the need for an emulator; features 8 kB ISP Flash and 768 bytes of RAM, supporting in-system programming and data storage.
• Wide Temperature and Reliable Packaging：
  Housed in 28-QFN or 32-LQFP packages, operating from –40°C to +85°C with 5V-tolerant I/O pins, ensuring stability in harsh environments.

Typical Applications

• Industrial Automation Control：
  Implements high-precision analog signal acquisition and real-time control in PLCs and sensor nodes, supporting precise PWM for multi-axis motor drives via SPI/SMBus communication.
• Medical Instrumentation：
  Used in monitoring devices for biomedical signal processing, with 24-bit ADC ensuring low-noise data acquisition and low-power modes extending battery life.
• Smart Sensors：
  Adapts to signal conditioning for temperature, humidity, and pressure sensors. Built-in temperature sensor and PGA simplify front-end design, suitable for IIoT edge devices.
• Automotive Electronics：
  Meets in-vehicle diagnostic (OBD) and body electronics requirements, with wide temperature tolerance and noise immunity for engine compartment and in-vehicle network environments, supporting CAN bus cascading.
• Portable Devices：
  Enables low-power data processing in handheld meters and wearables, with Stop mode current as low as 0.1 µA. On-chip debugging accelerates development cycles.
