A96G174FU

The A96G174FU is an 8-bit CMOS microcontroller based on an M8051-compatible core, offering 8 Kbytes of on-chip Flash and a broad peripheral set for embedded control applications and low-power systems. It combines internal memory, a 12-bit ADC with multiple channels, flexible timers and PWM, and serial interfaces to deliver a compact, integrated platform for control and sensing tasks.

Key Features

• Core  8-bit CISC M8051-compatible core (2 clocks per cycle) with typical instruction timing supported by internal high-speed RC options.
• Memory  8 Kbytes of on‑chip Flash (ISP capable) with 256 bytes IRAM and 256 bytes XRAM (total RAM 0.5 Kbytes) for program and data storage.
• Clock & Oscillators  Internal RC oscillators include HSIRC 32 MHz and LSIRC 128 kHz, providing flexible clocking options for performance and low-power operation.
• Voltage & Power  Wide operating VCC/VDD range of 1.8–5.5 V and power-saving modes including STOP and IDLE to optimize energy use in battery-powered designs.
• Timers & PWM  Multiple timers including BIT (8-bit), T0 (8-bit), T1/T2 (16-bit), an 8-bit PWM and 16-bit complementary PWM with programmable pulse generation for motor or actuator control.
• Analog  12-bit A/D converter with up to 15 input channels and internal bandgap reference (typ. 1.20 V) for high-resolution sensor interfacing.
• Interfaces  USART (or SPI option) ×1 and I2C ×1 for serial communications; general-purpose I/O with 18 normal I/O ports for external device control and user interfaces.
• System Reliability  On-chip Power-On Reset (POR), Low Voltage Reset (5 selectable levels), Low Voltage Indicator (3 levels), and Window Watchdog Timer (WWDT) for robust operation.
• Package & Temperature  Available in a compact 20‑QFN package (3 × 3 × 0.75–0.4 mm) and rated for operation from −40 °C to +85 °C.

Typical Applications

• Embedded control  Use the A96G174FU for general embedded control tasks where an 8051-compatible MCU with integrated timers, PWM and serial interfaces is required.
• Sensor-based systems  Leverage the 12-bit ADC with up to 15 channels and I2C to capture and process analog sensor inputs with fine resolution.
• Motor and actuator control  Employ the 8-bit and 16-bit timers plus complementary PWM and programmable pulse generation for precise drive and timing control.
• Low-power products  Deploy in battery-powered or energy-sensitive designs that benefit from wide operating voltage (1.8–5.5 V) and STOP/IDLE power-saving modes.

Unique Advantages

• Integrated analog and timing peripherals: 12-bit ADC with multiple channels combined with PWM and 16-bit timers reduces external component count for sensing and control.
• Compact, production-ready memory: 8 Kbytes of on-chip Flash with in-system programming (ISP) and defined endurance simplifies firmware deployment and updates.
• Flexible serial connectivity: Built-in USART (or SPI option) and I2C provide multiple paths for communication and peripheral interfacing without external transceivers.
• Wide voltage range and power modes: 1.8–5.5 V operation plus STOP and IDLE modes enable use across a variety of power domains and energy budgets.
• Robust reset and watchdog features: POR, selectable low-voltage reset levels, low-voltage indicators and a window WDT help maintain reliable operation in field conditions.
• Small form-factor packaging: 20‑QFN (3×3 mm) allows dense, space-constrained board designs while providing 18 GP I/O pins.
