• Memory 16 Kbytes on‑chip Flash with In‑System Programming (ISP) and 30,000 cycle endurance; 256 bytes IRAM and 512 bytes XRAM for runtime data and stack.
• Power and Reset Wide supply range (1.8–5.5 V), on‑chip Power‑On Reset (POR), Low Voltage Reset (16 detect levels) and Low Voltage Indicator (13 levels) for reliable startup and monitoring.
• Timers & PWM Multiple timers including Basic Interval Timer (BIT), Watch Timer (WT), Window Watchdog Timer (WDT), one 8‑bit timer and two 16‑bit timers; programmable pulse generation and 16‑bit complement PWM with dead‑time control.
• Analog 12‑bit A/D converter supporting 8 channels at up to 133 ksps, plus one internal reference input channel for sensor and analog signal acquisition.
• Interfaces Communication peripherals include two USART channels (UART/SPI capable), I2C ×1, enabling flexible host and peripheral interfacing options.
• System Reliability Hardware CRC‑16, Watch Dog Timer and Window WDT provide system integrity and fault‑recovery mechanisms.
• GPIO & Drive 18 general‑purpose I/O lines with up to four high‑current sink ports and dedicated LED driver/buzzer support for direct user‑interface control.
• Oscillators & Low Power Internal and external oscillator support, internal RC oscillators (HSI 32 MHz and LSI 128 kHz) and power‑down modes (STOP, IDLE) for flexible clocking and energy management.
• Package & Temperature Available in a 20‑TSSOP surface‑mount package and specified for operation from –40°C to +85°C.

Typical Applications

• Home appliance control Manage user interfaces, timers and actuators using integrated PWM, timers, high‑current ports and ADC channels for sensor feedback.
• Consumer and industrial control Implement control logic, communication (USART, I2C) and system monitoring for compact appliances and automation modules.
• Sensor interfacing and data acquisition Multi‑channel 12‑bit ADC and internal reference support precise analog measurement and signal conditioning for sensor systems.
• Human‑machine interface Drive LEDs and buzzers directly from high‑current ports while handling input scanning and serial communication for displays and keypads.

Unique Advantages

• Highly integrated peripheral set: Combines ADC, timers, PWM, USART, I2C and hardware CRC‑16 on a single die to reduce BOM and board complexity.
• Flexible power and clocking: Internal and external oscillator support plus STOP/IDLE modes and a wide 1.8–5.5 V supply range enable use across battery‑powered and mains‑driven designs.
• Robust I/O and drive capability: 18 GPIOs with dedicated high‑current ports and LED/buzzer drivers simplify direct control of indicators and small actuators.
• Reliable system management: On‑chip POR, multi‑level LVR/LVI, Watch Dog Timer and Window WDT enhance system resilience and fail‑safe behavior.
• In‑System Programmable Flash: 16 Kbytes of Flash with ISP and 30,000 cycle endurance supports field updates and iterative development.
• Industry‑ready temperature range: Specified operation from –40°C to +85°C for deployment in demanding environments.
