The A96S174 is an advanced CMOS 8-bit microcontroller from ABOV Semiconductor, built around an M8051-compatible core. It combines an 8 Kbyte on-chip Flash, integrated analog and digital peripherals, and power-management features for flexible embedded control applications.

Targeted for cost-effective embedded systems, the device offers a mix of serial interfaces, multi-channel 12-bit A/D conversion, multiple timers and PWM options, and on-chip reset and voltage-detection features to simplify system design and reliability.

Key Features

• Core  8-bit CISC M8051 core (8051 compatible) with a minimum instruction execution time of 125 ns at 16 MHz (2 clocks per cycle).
• Memory  8 Kbytes on-chip FLASH (In-System Programming supported, endurance 30,000 cycles), 256 bytes IRAM and 256 bytes XRAM for application and data storage.
• Clock & Performance  Internal RC oscillators (HSIRC 32 MHz and LSIRC 128 kHz) and operation up to 16 MHz with the internal oscillator.
• Analog  12-bit ADC with 14 input channels and internal band-gap reference (typ. 1.20 V) for multi-channel sensor interfacing.
• Timers & PWM  Multiple timer options including Basic Interval Timer (8-bit), Window WDT (8-bit), Timer0 (8-bit), Timer1/Timer2 (16-bit), 8-bit PWM (T0) and 16-bit complementary PWM (T1).
• Serial Interfaces  Integrated serial connectivity including USART (configurable), I2C (1 channel) and flexible serial options for system communication.
• System Reliability  On-chip Power-On Reset (POR), Low Voltage Reset (LVR) with five detect levels, Low Voltage Indicator (LVI) with three detect levels, Watchdog Timer (WDT) and Window WDT for safe operation.
• Power Management  STOP and IDLE power-saving modes plus wide operating supply range of 1.8 V to 5.5 V for flexible power designs.
• I/O and Package  18 general-purpose I/O pins in a compact 20‑QFN package (3.0 × 3.0 × 0.75–0.4 mm), surface-mount ready.
• Environmental Range  Operating temperature range from −40 °C to +85 °C for a broad range of operating environments.

Typical Applications

• Home Appliances  Control and user-interface tasks in small appliances where compact packages, multi-channel ADC and PWM control are required.
• Consumer Electronics  Sensor interfacing, status monitoring and serial communication in battery- or mains-powered devices using its wide supply range and power-saving modes.
• Industrial Control  Embedded control functions and timer/PWM-driven actuation in compact systems requiring reliable reset and voltage-detection features.
• Sensor Hubs & Monitoring  Multi-channel 12-bit ADC and internal reference make the device suitable for aggregating and digitizing multiple analog sensors.

Unique Advantages

• Highly integrated peripheral set: On-chip ADC, timers, PWM, USART and I2C reduce external component count and simplify board design.
• Flexible power and clock options: Internal RC oscillators and STOP/IDLE modes plus 1.8–5.5 V operation enable diverse power architectures and low-power operation.
• Robust reset and voltage supervision: POR, multi-level LVR and LVI plus WDT/Window WDT improve system resilience against supply and fault conditions.
• Compact surface-mount package: 20‑QFN (3 × 3 mm) provides a small PCB footprint for space-constrained applications.
• In-System Programmable FLASH: 8 Kbytes FLASH with ISP capability and 30,000 cycle endurance supports field updates and iterative firmware development.
• True sensor interfacing: 12-bit ADC with 14 channels and internal band-gap reference allow precise multi-channel analog measurement without external reference components.
