A96G148CU

The Abov A96G148CU is an 8-bit CMOS microcontroller based on an M8051-compatible core, designed for embedded control applications requiring integrated analog, timing and I/O resources. It combines 32 Kbytes of on‑chip Flash and 2.5 Kbytes of RAM with up to 46 GPIOs and a 12‑bit, 16‑channel ADC to address sensor interfacing, UI control and motor/power management tasks.

On-chip peripherals include multiple timers and PWM channels, multi‑mode serial interfaces and system reliability features (POR, LVR/LVI, watchdog), plus internal and external oscillator support and power‑saving STOP/IDLE modes for low‑power designs. The device supports a wide supply range (1.8–5.5 V) and extended operating temperatures to suit a variety of embedded environments.

Key Features

• Core  M8051-compatible 8‑bit CISC core with 2 clocks per cycle, supporting instruction execution timing down to 125 ns at 16 MHz main clock.
• Memory  32 Kbytes of on‑chip Flash (ISP capable, 30,000 program/erase endurance) and 256 bytes IRAM plus 2,304 bytes XRAM (total 2.5 Kbytes RAM).
• Power  Wide operating supply 1.8–5.5 V and power‑down modes (STOP, IDLE) for energy‑sensitive applications; POR and configurable low‑voltage reset/indicator (multiple detect levels).
• Timers & PWM  Comprehensive timing: 1 × 8‑bit basic interval timer (BIT), 1 × 8‑bit T0, 5 × 16‑bit timers (T1–T5) and PWM support (8‑bit PWM plus pulse generation from T1–T5); watchdog and watch timer with selectable intervals.
• Analog  12‑bit A/D converter with 16 input channels for precision sensor acquisition and monitoring.
• Serial Interfaces  Flexible USI channels (multi‑mode: USART/SPI/I2C) and USART functionality for UART/SPI communications and host/user connectivity.
• GPIO & Drivers  Up to 46 general‑purpose I/O pins with high‑sink current ports and LED/buzzer driver capabilities for direct actuator and indicator control.
• System Reliability  Includes Power‑On Reset (POR), Low Voltage Reset (LVR) / Low Voltage Indicator (LVI) with multiple threshold levels, watchdog timer (WDT) and In‑System Programming (ISP) support.
• Oscillators  Supports internal RC oscillators (HSI up to 32 MHz and LSI sub‑clock options) and external crystal/ceramic resonators for main and sub clocks.
• Package & Temperature  Available in a 48‑QFN package and rated for industrial operating temperature from −40 °C to +85 °C.

Typical Applications

• Embedded Control  Microcontroller tasks such as relay control, timing and state management where integrated timers, PWM and watchdog improve reliability.
• Sensor Interfacing  Multi‑channel 12‑bit ADC enables precise acquisition from multiple sensors for monitoring and control systems.
• User Interface & Indicators  High‑current ports, LED driver and buzzer support make it suitable for display and alert functions in appliances and consumer devices.
• Motor & Power Management  Multi‑channel PWM and 16‑bit timers support motor drive control and power sequencing in household and industrial products.

Unique Advantages

• Highly integrated peripheral set: ADC, multiple timers/PWM, GPIO drivers and multi‑mode serial interfaces reduce external components and simplify board design.
• Flexible clocking: Internal and external oscillator options (including a 32 MHz internal RC) enable a range of performance and power tradeoffs without extra hardware.
• Wide voltage range: 1.8–5.5 V supply support allows operation across battery‑powered and mains‑referenced systems with the same MCU.
• Robust system features: POR, multi‑level LVR/LVI, watchdog and watch timer provide built‑in protection and recoverability for reliable operation.
• Field programmable Flash: 32 Kbytes of in‑system programmable Flash with 30,000 endurance cycles supports firmware updates and iterative development.
• Industrial temperature capability: Operation from −40 °C to +85 °C supports applications across a broad range of ambient temperatures.
