• Analog  High-resolution converters including a 12-bit ADC with 14 channels and a 12-bit DAC for precision sensing and analog output.
• Display & UI  Integrated LCD driver (29×8) plus LED driver / high-current port (11×25) and 20-channel touch key support for advanced user interfaces.
• System Reliability & DMA  On-chip CRC, two comparators, 4-channel DMA and Watch Dog Timer for reliable operation and efficient data movement.
• I/O & Package  58 general-purpose I/O lines in a 64-LQFP surface-mount package, suitable for densely integrated appliance controller boards.
• Operating Range  Specified operating temperature from −40 to 85 °C for industrial and appliance environments.

Typical Applications

• Home Appliances  Designed for appliance main controller applications: combines motor PWM, display drivers and multiple serial interfaces for integrated appliance control.
• Motor and Power Control  3-phase 16-bit PWM and multiple timers enable precise control of motors and power stages in compact systems.
• User Interface Control  On-chip LCD and LED drivers together with touch-key channels simplify implementation of advanced front panels and displays.
• Sensor and Peripheral Hub  Multiple serial interfaces (I2C, SPI, UART, USART) and a 12-bit ADC provide direct connectivity for sensors and external peripherals.

Unique Advantages

• Highly integrated peripherals: 3-phase PWM, ADC/DAC, LCD and LED drivers reduce external component count and simplify BOM.
• Flexible I/O and package options: 58 GPIOs in a 64-LQFP surface-mount package support complex board-level integration without sacrificing pin count.
• Robust analog capabilities: 12-bit ADC (14 channels) and 12-bit DAC provide precise analog interfacing for sensing and control tasks.
• Efficient real-time control: ARM Cortex-M0+ core at 48 MHz with DMA and multiple timers enables deterministic control with low software overhead.
• Wide voltage and temperature range: 1.8–5.5 V supply range and −40 to 85 °C operating temperature allow use across varied appliance and industrial environments.
