• Power and Clock Wide operating voltage 1.8–5.5 V and support for internal and external oscillators. Multiple low-power modes including STOP and IDLE, plus on-chip POR, LVR and LVI for reliable reset and voltage supervision.
• Timers & PWM Multiple timers including Basic Interval Timer (BIT), Watch Timer (WT), Window Watchdog Timer (WDT), one 8-bit timer (T0) and two 16-bit timers (T1/T2). Programmable pulse generation with 16-bit complement PWM and dead-time control.
• Analog 12-bit A/D converter with device-specific external input channels (A96G166GR variant includes 12 external ADC inputs) plus an internal reference channel for accurate sensor interfacing.
• Interfaces Communication peripherals include USART (x2, configurable as UART or SPI), one I2C channel. Receiver timeout and 0% error baud rate features enhance serial reliability.
• I/O and Drive Up to 26 general-purpose I/O with up to 8 high-sink current ports and dedicated LED driver/high-current port capability; integrated buzzer output for user feedback.
• System Reliability On-chip Watchdog Timer, Window WDT, Watch Timer, Hardware CRC-16 engine, Power-on Reset and selectable Low Voltage Reset/Indicator levels for robust system supervision.
• Package & Temperature Available in 28‑TSSOP (173 mil) surface-mount package and specified for operation from –40 °C to +85 °C.

Typical Applications

• Home Appliances Embedded control for appliances—user interface, motor/timer management and sensor monitoring—leveraging integrated ADC, timers and high-current I/O.
• Consumer Electronics Control and user-feedback functions such as LED/buzzer drivers and serial interfaces for display or peripheral communication.
• Sensor Measurement & Monitoring Precision 12-bit ADC and multiple input channels enable accurate sensor sampling and system monitoring in battery-powered or mains-powered equipment.
• General Embedded Control Applications requiring reliable reset supervision, watchdog protection and flexible PWM/timer control for power and motor management.

Unique Advantages

• Balanced 8-bit performance: The M8051 core with up to 16 MHz operation delivers predictable instruction timing (125 ns at 16 MHz) for real-time control tasks.
• Integrated mixed-signal peripherals: On-chip 12-bit ADC, multiple timers, PWM complement control and hardware CRC-16 reduce external components and simplify PCB design.
• Flexible power and clocking: Support for internal and external oscillators plus wide 1.8–5.5 V supply range enables design scalability across low-voltage and standard-voltage systems.
• Robust system supervision: POR, programmable LVR/LVI levels, Watchdog and Window WDT provide layered protection for reliable operation in fielded systems.
• Compact, manufacturable package: 28‑TSSOP surface-mount package offers a space-efficient footprint with up to 26 GPIO and up to 8 high-sink ports for direct drive of indicators and actuators.
