A96G174FR

The A96G174FR is an 8-bit CMOS microcontroller based on an M8051-compatible CISC core, integrating 8 Kbytes of on‑chip Flash and a broad set of analog and digital peripherals for embedded control applications. It targets compact control and sensing designs that require on‑board A/D conversion, versatile timers, serial interfaces and low‑power operation across a wide supply range.

With internal oscillator options, watchdog and reset circuitry, and multiple power‑save modes, the device provides an integrated platform for reliable, low‑power embedded systems in a 20‑TSSOP package.

Key Features

• Core 8‑bit M8051 compatible CISC core (2 clocks per cycle) supporting standard 8051 instruction flow and development approaches.
• Memory 8 Kbytes on‑chip Flash (in‑system programming, endurance 30,000 cycles), 256 bytes IRAM and 256 bytes XRAM for program and data storage.
• Clock and Performance Internal RC oscillators including HSIRC 32 MHz and LSIRC 128 kHz; main clock operation up to 16 MHz.
• Analog 12‑bit A/D converter with 15 input channels and up to 133 ksps, accompanied by an internal bandgap reference (typ. 1.20 V) for accurate sensor interfacing.
• Timers & PWM Multiple timers including Basic Interval Timer (BIT), 8/16‑bit timer/counters (T0/T1/T2), 8‑bit PWM and 16‑bit complementary PWM plus programmable pulse generation for motor or actuator control.
• Serial Interfaces On‑chip USART (with receiver timeout and 0% error baud rate capability) and I2C controller provide standard serial connectivity for peripherals and system communication.
• System Reliability On‑chip Power‑On Reset (POR), Low Voltage Reset (multiple levels), Low Voltage Indicator, Window Watchdog Timer (WWDT) and standard WDT for robust system supervision.
• Power Management Power saving modes including STOP and IDLE, and wide operating supply range of 1.8 V to 5.5 V for flexible power budgets and battery‑aware designs.
• I/O and Packaging 18 general‑purpose I/O pins in a compact 20‑TSSOP surface‑mount package (173 mil) suitable for space‑constrained PCBs.
• Operating Range Specified operating temperature range from −40 °C to +85 °C to support a variety of environmental conditions.

Typical Applications

• Embedded control — Core MCU and integrated timers/peripherals provide a compact platform for general embedded control tasks and appliance control logic.
• Sensor interface and data acquisition — 12‑bit, 15‑channel ADC enables multi‑sensor sampling for environmental, industrial or consumer sensing nodes.
• Motor and actuator control — Programmable pulse generation, complementary 16‑bit PWM and 8‑bit PWM support precise timing and drive signals for small motors and actuators.
• Human interface and communication modules — USART and I2C support user interfaces, display drivers and peripheral communication in compact systems.

Unique Advantages

• Highly integrated peripherals: Extensive on‑chip timers, PWM, PPG, ADC and serial interfaces reduce system BOM and simplify board design.
• Flexible power and voltage support: 1.8–5.5 V operating range plus STOP/IDLE modes enable deployment across battery‑powered and mains systems.
• Robust system supervision: POR, multiple LVR/LVI levels and Window WDT/WDT help maintain reliable operation in variable supply and noisy environments.
• Compact footprint: 20‑TSSOP package with 18 GPIOs balances I/O density and PCB area for space‑constrained products.
• Proven 8051 architecture: M8051 compatibility eases software migration and leverages established toolchains for development efficiency.
• High‑resolution sensing: 12‑bit ADC with 15 channels at up to 133 ksps supports multi‑channel analog monitoring and control tasks.
