Key Features

• Core ARM Cortex‑M0+ 32‑bit core delivering efficient control performance at clock speeds up to 40 MHz.
• Memory 32 Kbytes of internal flash and 6 Kbytes of SRAM suitable for firmware, control algorithms and runtime data.
• Voltage & Temperature Wide supply range of 1.8–5.5 V and industrial operating temperature up to −40 to 105 °C for robust deployments.
• Timers & PWM Multiple general‑purpose timers including 16‑bit timers, 32‑bit timers and a 16‑bit timer with six‑channel PWM for motor, motor‑driver or power control and precise timing functions.
• Analog 12‑bit ADC with 14 input channels (50 ksps) for multi‑sensor acquisition and precise signal monitoring.
• Connectivity Rich communication set including multiple USART (UART + SPI), UART channels and I2C ports for device and host interfacing.
• Display & GPIO Integrated LCD driver/controller and LED driver plus up to 77 I/O pins; LCD support to drive up to 8×39 segments and dedicated sink capability on PD0–PD7.
• System Reliability & Security On‑chip POR, LVR, LVI, 24‑bit watchdog timer, clock monitoring and a 16‑bit CRC generator (CRC‑CCITT/CRC‑16) for system safety and data integrity.
• Oscillators & Debug Internal RC oscillator and external clock support, plus SWD debug interface and support for USART (UART + SPI) ISP to streamline development and programming.
• Package Available in an 80‑lead LQFP package (80‑LQFP) suitable for surface‑mount assembly.

Typical Applications

• Smart Door Locks Microcontroller core, secure timers and multiple comms interfaces make it well suited for access control, keypad and wireless module integration.
• Air Cleaners & Home Appliances ADC channels, PWM outputs and robust I/O allow motor control, sensor interfacing and user‑display management in household appliances.
• General‑Purpose Embedded Control Combination of timers, communications and display drivers supports diverse control and HMI tasks across small embedded products.

Unique Advantages

• Highly integrated peripheral set: On‑chip ADC, multiple timers, PWM channels, LCD/LED drivers and CRC reduce external components and simplify BOM.
• Flexible power and temperature range: 1.8–5.5 V operation and −40 to 105 °C rating support battery and industrial environments.
• Comprehensive connectivity: Multiple USART (UART + SPI), UART and I2C options enable a wide range of sensor, actuator and host interfaces.
• Development and production support: SWD debug interface and USART ISP support speed firmware development and in‑field programming.
• Display‑capable I/O: Built‑in LCD controller and LED driver with dedicated sink capability simplify implementation of user interfaces and status indicators.
