A96G140GR

The A96G140GR is an advanced CMOS 8-bit microcontroller from Abov’s A96G14x series, built around an M8051-compatible CISC core. It integrates up to 64 Kbytes of on-chip Flash, a 12-bit A/D converter, multiple timers and PWM/PPG channels, and on-chip power and clock management to address compact embedded control applications.

Designed for cost-effective, highly integrated control tasks, the device delivers flexible I/O, mixed-signal peripherals and power-saving modes for applications that require reliable operation across a broad voltage and temperature range.

Key Features

• Core  M8051-compatible 8-bit CISC core with 2 clocks per cycle and up to 16 MHz main clock operation for responsive control.
• Memory  Up to 64 Kbytes on-chip Flash with In-System Programming (ISP) and endurance specified in the datasheet; internal RAM split available (256 bytes IRAM + 2,304 bytes XRAM, total ~2.5 Kbytes).
• Analog  12-bit A/D converter for precise data acquisition (11 input channels on this 28-TSSOP variant), suitable for sensor interfacing and measurement tasks.
• Timing, PWM & Buzzer  Multiple timers including 8-bit and 16-bit timers, Watch Dog Timer (WDT), Watch Timer (WT) and programmable pulse generation (PPG); dedicated buzzer driving port for user feedback.
• Interfaces  USI0/1 supporting USART, SPI and I²C modes plus an additional USART/SPI channel, providing flexible serial connectivity options.
• Power & Clock Management  On-chip oscillator (internal and external options), Power-On Reset (POR), Low-Voltage Reset (LVR) with multiple detection levels, and Low-Voltage Indicator (LVI).
• Low Power Modes  STOP and IDLE power-down modes to reduce power consumption in battery-powered or energy-sensitive designs.
• GPIO & I/O  Up to 26 general-purpose I/O on the 28-TSSOP package with high-current sink capability available on specified ports in the series.
• Voltage & Temperature  Wide operating voltage range from 1.8 V to 5.5 V and an extended operating temperature capability of −40 °C to +85 °C.
• Package  Surface-mount 28-TSSOP package for compact board-level integration.

Typical Applications

• Embedded control systems  Core 8-bit control, timers and GPIO combine for general-purpose embedded control tasks and state-machine driven applications.
• Sensor interfacing & data acquisition  12-bit ADC and multiple timers enable accurate sampling and timing for sensor hub and measurement applications.
• User interface and audio feedback  GPIO, timer-driven PWM/PPG and the dedicated buzzer port support user interfaces, status signaling and simple audio feedback.
• Power-managed portable devices  On-chip POR, LVR/LVI and STOP/IDLE modes help implement robust, low-power designs across a broad supply voltage range.

Unique Advantages

• Highly integrated peripheral set: On-chip Flash, ADC, multiple timers, PWM/PPG and serial interfaces reduce external components and simplify BOM.
• Flexible serial connectivity: USI0/1 supporting USART, SPI and I²C plus an additional USART/SPI channel gives designers multiple communication options without extra transceivers.
• Robust power and reset handling: POR, configurable LVR and LVI levels and internal oscillators improve reliability across supply and startup conditions.
• Broad supply and temperature range: 1.8–5.5 V operation and support for −40 °C to +85 °C allow deployment in varied environments and supply scenarios.
• Compact SMD package: 28-TSSOP surface-mount package enables small form-factor PCB designs while exposing a practical set of I/O for control tasks.
