A96G140SQ

The A96G140SQ is an 8-bit CMOS microcontroller in Abov’s A96G14x series based on an M8051-compatible core. It integrates up to 64 Kbytes of on-chip Flash, 2.5 Kbytes of RAM (IRAM + XRAM), a 12-bit 16-channel ADC and a broad set of timers and peripherals tailored for embedded control applications.

Designed for appliance, consumer and industrial control markets, the device delivers flexible voltage operation (1.8–5.5 V), selectable internal and external oscillators and multiple low-power modes to balance performance and energy efficiency in space-constrained surface-mount designs.

Key Features

• Core  M8051-compatible 8-bit CISC core with 2 clocks per cycle and typical main-clock operation up to 16 MHz (minimum instruction execution time: 125 ns at 16 MHz).
• Memory  64 Kbytes on-chip Flash with in-system programming and 2.5 Kbytes total RAM (256 bytes IRAM + 2,304 bytes XRAM) for application code and runtime data.
• Timers & PWM  Multiple timer resources including one 8-bit basic interval timer, one 8-bit watchdog timer, one 8-bit timer (T0) and five 16-bit timers (T1–T5). PWM support includes one 8-bit PWM and multiple 16-bit programmable pulse generation/PWM channels.
• Analog & Data Conversion  12-bit A/D converter with 16 input channels for precision sensor interfacing and analog monitoring.
• Interfaces & Communications  Multiple serial interfaces including USART channels and USI (configurable for USART/SPI/I2C) to support common peripheral and networked device interfaces.
• System Reliability  On-chip watchdog timer (WDT), Power-On Reset (POR), Low Voltage Reset (LVR) with multiple thresholds and Low Voltage Indicator (LVI) for controlled startup and brownout protection.
• Power & Low-Power Modes  Internal RC oscillators (HSI 32 MHz and LSI 128 kHz with specified accuracies), external crystal support and power-down modes including STOP and IDLE for reduced standby consumption.
• GPIO & High-Current I/O  Up to 42 general-purpose I/O pins with 8 high-sink current ports and dedicated buzzer drive and LED/high-current ports to simplify direct-drive of indicators and sounders.
• Package & Temperature Range  44-MQFP surface-mount package (10 × 10 mm, 0.8 mm pitch) and industrial operating temperature range from −40 °C up to +85 °C for demanding environments.

Typical Applications

• Home Appliances  Control and user-interface tasks such as keypad handling, display driving and motor control in household devices where integrated ADC and timers reduce external components.
• Consumer Electronics  Sensor interfacing, audio/buzzer control and peripheral communications in compact product designs that benefit from on-chip Flash and multiple serial interfaces.
• Industrial Control  Embedded control, timing and analog monitoring in industrial equipment that requires robust voltage range and industrial temperature operation.
• Appliance Motor & Power Control  PWM and multi-channel timers for motor drive control, dimming and power sequencing combined with low-voltage detection for safe operation.

Unique Advantages

• Highly integrated peripherals: Combines 12-bit ADC, multiple timers/PWM channels, watchdog and POR/LVR/LVI on-chip to reduce BOM and PCB area.
• Flexible clocking options: Internal high- and low-speed RC oscillators plus external crystal support let designers optimize performance versus power.
• Wide voltage range: Operates from 1.8 to 5.5 V to suit battery-powered and line-powered systems without additional power-domain components.
• Robust I/O capability: Up to 42 GPIOs including 8 high-sink ports and dedicated LED/buzzer drivers simplify direct device interfacing.
• In-system programmability: On-chip Flash with ISP support streamlines firmware updates and production programming.
• Industrial temperature suitability: Support for operation from −40 °C to +85 °C enables use in demanding environmental conditions.
