Overview of A96G166LU – Abov A96G166 8-bit Microcontroller (16 Kbytes Flash, 24-QFN)
The A96G166LU is an advanced CMOS 8-bit microcontroller based on the M8051 core, delivering up to 16 MHz operation with 16 Kbytes of on-chip Flash and 0.75 Kbytes of RAM. It integrates a broad set of analog and digital peripherals—12-bit ADC, multiple timers, USART and I2C interfaces, on-chip clocking and reset circuitry—making it well suited for compact, low-power embedded applications.
Packaged in a compact 24-pin QFN (4×4‑0.5 mm) and supporting a wide 1.8–5.5 V supply range and extended temperature operation, the A96G166LU targets designs requiring integration, flexible I/O and reliable system features in a small footprint.
Key Features
- Core – 8-bit M8051 CISC core with up to 16 MHz main-clock operation (minimum instruction time 125 ns at 16 MHz).
- Memory – 16 Kbytes on-chip FLASH with In-System Programming (ISP) and 30,000 cycle endurance; 0.75 Kbytes of RAM (256 bytes IRAM + 512 bytes XRAM).
- Analog – 12-bit A/D converter with 11 external input channels (package-specific), plus an internal reference input channel for sensor interfacing and accurate measurement.
- Timers & PWM – 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 for motor or power control tasks.
- Interfaces & Connectivity – Dual USART (configurable as UART or SPI), I2C (1‑channel); flexible serial options for sensor buses, user interfaces and peripheral control.
- GPIO & Drivers – Up to 22 general-purpose I/O pins in the 24‑QFN package, including high‑current sink ports (4 high‑current ports / LED drivers) for direct drive of indicators and basic loads.
- System Reliability – On-chip POR, Low Voltage Reset (LVR), Low Voltage Indicator (LVI) with multi-level detect, and hardware CRC-16 for data integrity and robust boot/reset behavior.
- Clocking & Power – Internal and external oscillator support with internal RC oscillators (HSI/LSI), plus power‑saving STOP and IDLE modes to optimize battery‑powered applications.
- Operating Range & Package – Wide supply range 1.8–5.5 V, operating temperature from −40 °C to +85 °C, and a compact 24‑QFN (4×4‑0.5 mm) surface‑mount package for space‑constrained designs.
Typical Applications
- Home Appliances – Control user interfaces, timers and basic motor or actuator functions using the integrated timers, PWM and multiple I/O.
- Portable & Battery-Powered Devices – Low-voltage operation and power-saving STOP/IDLE modes help extend battery life while supporting sensor acquisition via the 12-bit ADC.
- Sensor and Measurement Modules – 12-bit ADC and internal reference channel provide high-resolution analog input for sensor interfacing and condition monitoring.
- Consumer Electronics Control – Dual USART/I2C and GPIO with high-current sink ports simplify user interface, LED driving and peripheral communication tasks.
Unique Advantages
- Highly integrated peripheral set: Combines ADC, multiple timers, PWM, CRC and serial interfaces to reduce BOM and simplify system design.
- Flexible power and clock options: Internal and external oscillator support plus wide 1.8–5.5 V supply range enable use across battery and line-powered designs.
- Compact package for space-constrained designs: 24‑QFN (4×4‑0.5 mm) delivers a small footprint while retaining 22 GPIOs and dedicated high-current ports.
- Robust system features: On-chip POR, multi-level LVR/LVI and Window WDT help improve system reliability and predictable reset behavior.
- In-System Programmable Flash: 16 Kbytes FLASH with ISP and 30,000 cycle endurance supports field updates and iterative development.
