A96G174FD

The A96G174FD is an 8-bit CMOS microcontroller based on an 8051-compatible CISC core, designed as a compact, cost-effective solution for embedded control applications. It combines on-chip Flash, RAM, a 12-bit ADC and a set of timers and serial interfaces to support sensor interfacing, motor control and general-purpose embedded tasks.

With on-chip power management, internal oscillator options and low-power modes, the device is suited to designs that require flexible integration, modest processing performance and reduced external BOM.

Key Features

• Core 8-bit M8051-compatible CISC core (8051 compatible) with 2 clocks per cycle and up to 16 MHz operating frequency.
• Memory 8 Kbytes on-chip Flash with in-system programming (ISP) and 30,000 write endurance; 256 bytes IRAM and 256 bytes XRAM (total 0.5 KB RAM).
• Power and Voltage Wide supply range of 1.8 V to 5.5 V with on-chip power-on-reset (POR) and selectable low-voltage reset (LVR) and low-voltage indicator (LVI) levels.
• Timers & PWM Multiple timers including Basic Interval Timer (8-bit), Window Watchdog Timer (8-bit), Timer0 (8-bit) and Timer1/Timer2 (16-bit), plus 8-bit PWM and 16-bit complementary PWM and 16-bit PPG outputs for motor and timing control.
• Analog 12-bit A/D converter with 15 input channels and up to 133 ksps, and internal bandgap reference (typ. 1.20 V).
• Interfaces USART (single 8-bit channel, which can operate as SPI), and a single I2C channel for common serial peripherals and sensor networks. Receiver timeout and precise baud features are provided for robust serial communication.
• System Reliability Watchdog timer (WDT) and Window WDT, power-on reset (POR), and selectable LVR/LVI levels help ensure reliable operation in variable supply conditions.
• Clock & Low-Power Internal RC oscillators (HSIRC and LSIRC variants) with documented frequency and tolerance characteristics, plus STOP and IDLE power-down modes for reduced energy consumption.
• Package & I/O 18 general-purpose I/O pins in a 20-SOP (300 mil) surface-mount package; selection of package types shown in the device family documentation.
• Temperature Options Specified for operation from −40 °C to +85 °C.

Typical Applications

• Home Appliances – Control of small motors, user interfaces and timing functions using integrated PWM, timers and GPIO.
• Sensor Hubs and Data Acquisition – Multi-channel 12-bit ADC and I2C/USART connectivity for interfacing sensors and collecting analog data.
• Consumer & Industrial Controls – Embedded control tasks that require compact Flash/RAM, watchdog protection and flexible timing/peripheral options.

Unique Advantages

• Highly integrated MCU: On-chip Flash, dual RAM blocks, ADC, timers, PWM and serial interfaces reduce external components and simplify board design.
• Flexible power envelope: 1.8 V to 5.5 V supply range with POR, LVR and LVI options enables operation across diverse power configurations.
• In-system programmability: 8 Kbytes of Flash with ISP capability and documented endurance supports field updates and iterative development.
• Robust analog front end: 12-bit ADC with 15 channels and internal reference delivers precise sensor measurement capability without external ADCs.
• Compact footprint: 20-SOP surface-mount package and 18 GPIOs provide a small-board, space-efficient solution for embedded products.
• Power management and reliability features: Internal oscillators, STOP/IDLE modes, WDT/WWDT and POR support energy-efficient, dependable operation.
