• Analog & Data Conversion  12‑bit ADC with 14 channels supporting up to 150 ksps and a 12‑bit DAC for precise sensor acquisition and analog output generation.
• Motor & PWM  3‑phase PWM (16‑bit) and multiple timers (16‑bit and 32‑bit) suitable for motor drive and power control tasks.
• Display & User Interface  Integrated LCD driver (29×8), LED driver / high‑current port (11×25), and touch‑key support (20 channels) for rich local UI implementations.
• Connectivity  Multiple serial interfaces including I²C, UART and USART for sensors, peripherals and device communication.
• System & Reliability  On‑chip DMA (4 channels), CRC, comparator, PLL and a watchdog timer to support robust, real‑time applications.
• GPIO & Package  Up to 58 I/O pins in a 64‑LQFP package (10 × 10 mm, 0.5 mm pitch) in a surface‑mount form factor.

Typical Applications

• Home Appliances  Main controller for consumer appliances, handling UI, sensor fusion, and motor control with integrated PWM, ADC and display drivers.
• Consumer Electronics  Device control and peripheral management where compact integration of analog, digital and UI features is required.
• Motor and Power Control  3‑phase PWM and multi‑timer support enable development of compact motor-control systems and power-management functions.
• User Interfaces  Built‑in LCD, LED drivers and touch‑key channels simplify implementation of tactile and visual interfaces.

Unique Advantages

• Highly integrated peripheral set: Combines ADC, DAC, display drivers, touch key and PWM to reduce external components and BOM.
• Flexible power and temperature range: 1.8–5.5 V supply and −40 °C to 85 °C operation suit diverse consumer environments and power domains.
• Balanced memory footprint: 128 Kbytes Flash with 16 Kbytes SRAM provides space for feature-rich firmware while supporting efficient runtime data handling.
• Compact packaging: 64‑LQFP (10 × 10 mm) surface‑mount package enables space-efficient board layouts for compact products.
• Real-time data movement: On‑chip DMA (4 channels) and multiple timers reduce CPU load and improve deterministic control for real‑time tasks.
