• Power and Clock  Operates from 1.8 V to 5.5 V and supports multiple power modes (Run, Sleep, Power Down) with internal and external oscillator options and an integrated PLL.
• Timers and PWM  Comprehensive timer set including four 16-bit general-purpose timers, two 32-bit timers, and 16-bit 6-channel PWM plus dedicated 3-phase PWM support for motor/control applications.
• Analog  12-bit ADC with 14 input channels and a 5-bit DAC for sensor acquisition and simple analog output functions.
• Connectivity  Multi-port serial interfaces: 2 USART (UART + SPI), 2 UARTs, 2 SPIs and 2 I2C channels for sensors and peripherals.
• DMA and System  4-channel DMA engine, CRC generator (CRC-CCITT, CRC-16) and a Nested Vectored Interrupt Controller with 32 interrupt sources for robust data flow and error checking.
• User Interface  Capacitive touch support (24 channels) and an LED driver with 10 segments and 16 commons for front-panel controls and displays.
• Reliability and Safety  Includes a Watchdog Timer, real-time clock/calendar and two system reset sources (cold and warm) to support reliable operation.
• Package and I/O  48-pin LQFP (7 × 7 mm, 0.5 mm pitch) with 44 GPIOs for flexible board-level integration across appliance and consumer designs.

Typical Applications

• Home Appliances  Main controller for appliances requiring motor control, timing and human‑machine interface functions using integrated PWM, timers and touch/LED drivers.
• Consumer Electronics  Control and interface management for consumer devices that need mixed-signal sensing, serial peripherals and compact packaging.
• Motor and Power Control  3-phase PWM and multi-channel PWM/timer resources for brushless DC or multi-motor applications in small appliances.
• Sensor Hubs and IoT Peripherals  Multi-channel ADC, multiple serial buses (I2C/SPI/UART) and DMA enable efficient sensor data acquisition and preprocessing.

Unique Advantages
