• Memory 64 Kbytes of on-chip FLASH program memory and 6 Kbytes of SRAM to store application code and runtime data.
• Power and Clocks Wide operating voltage 1.8–5.5 V; multiple power modes including Run, Sleep and Power Down, plus internal/external oscillator support and PLL.
• Timers and PWM Multiple timers including four 16-bit general-purpose timers, two 32-bit timers, and 16-bit PWM functionality (3-phase PWM support) for motor drive and precise timing control.
• Analog 12-bit A/D converter with 8 channels and a 5-bit D/A converter for sensor interfacing and analog control loops.
• Connectivity Multiple serial interfaces including I2C, SPI, UART and USART to connect sensors, displays and peripherals.
• Peripherals and System Support Integrated CRC engine, 4-channel DMA, watchdog timer (WDT), low-speed internal oscillator (LSI 500 kHz), and touch-key support (13 channels) for user interfaces.
• LED and GPIO LED driver / high-current port support (8×8) and a total of 28 I/O pins for flexible board-level control.
• Package and Temperature Available in a 32-pin LQFP package with industrial-grade operating temperature up to –40 to +105 °C.

Typical Applications

• Home Appliances — Main controller for household appliances requiring motor control, user interfaces and sensor management.
