A96G166FD

The A96G166FD is an 8-bit CMOS microcontroller based on the M8051 core, offering 16 Kbytes of on-chip FLASH and a compact 20-SOP (300 mil) package. It is designed for embedded control applications that require integrated analog, timing and communications peripherals in a low-voltage, low-power footprint.

With an on-chip oscillator, selectable external/internal clock sources, multiple timers, a 12‑bit ADC and serial interfaces including I2C and USART, the A96G166FD targets designs that need balanced processing performance, analog input capability and system-level protection features across a wide supply and temperature range.

Key Features

• Core  M8051 8-bit CISC core with instruction timing down to 125 ns at a 16 MHz main clock.
• Program Memory  16 Kbytes on-chip FLASH with in-system programming (ISP) and endurance rated at 30,000 cycles.
• RAM  256 bytes IRAM plus 512 bytes XRAM (total 0.75 Kbytes) for stack and data storage.
• Clock and Oscillator  On-chip oscillator with support for internal and external clock sources and operation up to 16 MHz main clock.
• Analog  12-bit A/D converter with 8 external channels for precise sensor measurement and signal acquisition.
• Timers & PWM  Multiple timers including 8-bit T0 and two 16-bit timers (T1/T2), Basic Interval Timer, Watch Timer and programmable pulse generation with 16-bit complement PWM and dead-time control.
• Communications  USART and I2C interfaces provide flexible serial connectivity; USART channels support UART or SPI modes.
• Peripherals & I/O  Up to 18 general-purpose I/O pins, buzzer output, hardware CRC-16 and high-current port options for direct drive capability.
• Power & Protection  Wide supply range from 1.8 V to 5.5 V, Power-On Reset (POR), Low-Voltage Reset (LVR) with multiple detect levels and Low-Voltage Indicator (LVI).
• Reliability & Safety  Watchdog Timer (WDT), Window WDT, Watch Timer (WT) and various interrupt sources to support robust system monitoring and fault recovery.
• Package & Temperature  Surface-mount 20-SOP (300 mil) package rated for operation from −40 °C up to +85 °C.

Typical Applications

• Home Appliances  Embedded control and user-interface management where integrated ADC, timers and serial interfaces simplify system design.
• Consumer Electronics  Control of displays, key scanning and peripheral coordination using built-in GPIO, USART and PWM resources.
• Industrial Controls  Sensor interfacing and timing tasks leveraging the 12‑bit ADC, multiple timers and watchdog functions for dependable operation.

Unique Advantages

• Integrated FLASH with ISP: 16 Kbytes of on-chip FLASH supports in-system programming and field updates without external memory.
• Flexible power range: Operates from 1.8 V to 5.5 V to support a wide variety of battery- and line-powered designs.
• Rich peripheral set in a small footprint: ADC, PWM, multiple timers, CRC-16 and serial interfaces reduce BOM and PCB area compared to multi-chip solutions.
• System protection features: POR, LVR, LVI and multiple watchdog timers help maintain predictable behavior and simplify fault handling.
• Wide operating temperature: Specified operation from −40 °C to +85 °C enables deployment across a broad range of environments.
