• Memory — 16K bytes of FLASH program memory and 768 bytes of on-chip SRAM for program and data storage.
• Power — Wide operating voltage range of 1.8–5.5 V and low current consumption suitable for battery-operated systems.
• Timers & PWM — Multiple 8/16-bit timers and dedicated 8/16-bit PWM outputs for timing, duty-cycle control and motor/lighting drive tasks.
• Analog — 12-bit A/D converter for precision analog measurement and sensor interfacing.
• Interfaces — Integrated I2C, SPI and UART/USART serial peripherals for peripheral and host communications.
• System Reliability — On-chip watchdog timer (WDT), Power-On Reset (POR), Low-Voltage Indicator/Reset (LVI/LVR) and CRC support for improved system robustness.
• Clock Options — Support for internal and external oscillators to match design requirements.
• Package & Temperature — 32‑QFN (5 × 5 × 0.5 mm) surface-mount package; industrial operating range of -40 to 85 °C.

Typical Applications

• Battery-powered embedded systems — Leverage the 1.8–5.5 V range and low current consumption to extend battery life in portable devices.
• Sensor and data acquisition — The 12-bit ADC and up to 30 GPIO enable accurate analog measurement and multiple input channels for sensor nodes.
• Motor and power control — 8/16-bit PWM outputs and timers provide the control precision needed for small motor drives, fans or power-stage control.
• User interfaces and peripheral control — UART, I2C and SPI interfaces combined with ample I/O support displays, keypads and external peripherals.

Unique Advantages

• Highly integrated analog and control peripherals — On-chip 12-bit ADC, PWM channels and multiple timers reduce external components and simplify BOM.
• Flexible power envelope — 1.8–5.5 V operation enables compatibility with a wide range of battery chemistries and power rails.
• Compact surface-mount package — 32‑QFN (5 × 5 mm) provides a small footprint for space-constrained PCB layouts.
• Robust system features — Built-in WDT, POR and LVI/LVR improve reliability in unattended or remote applications.
• Comprehensive communications — I2C, SPI and UART/USART interfaces support diverse peripheral ecosystems and simplify integration.
• Documented and configurable — Flash protection and code protection options are referenced in the device documentation for secure and flexible product development.
