A96G140SN

The A96G140SN is an advanced CMOS 8-bit microcontroller from Abov's A96G14x series, built around a high-performance M8051-compatible core. It combines up to 64 Kbytes of on-chip Flash with a rich set of embedded peripherals to address flexible, cost-effective embedded control applications.

Designed for low-voltage operation and power-sensitive systems, the device supports internal and external clock sources, multiple timers and PWM outputs, a 12-bit ADC with 16 channels, watchdog and power management features, and a 44-LQFP package for compact surface-mount designs.

Key Features

• Core  8-bit M8051-compatible CISC core with a 2-clocks-per-cycle architecture for deterministic instruction timing.
• Flash Memory  64 Kbytes on-chip Flash with in-system programming (ISP) and 30,000 program/erase endurance cycles.
• RAM  256 bytes IRAM plus 2,304 bytes XRAM (total 2.5 Kbytes) for stack and data buffering.
• Timers & PWM  Multiple timers including one 8-bit BIT, one 8-bit WDT, one 8-bit timer and five 16-bit timers (T1–T5) enabling programmable pulse generation and 8-bit PWM support.
• Analog  12-bit A/D converter with up to 16 input channels (133 ksps) for accurate sensor interfacing and analog measurement.
• Connectivity  Dual USI channels (configurable as USART/SPI/I2C) and an additional USART channel for flexible serial communication options.
• I/O and Drive  42 general-purpose I/O pins with eight high-sink current ports for direct LED and high-current drive applications.
• Power & Clock  Wide operating voltage range (1.8–5.5 V), internal RC oscillators (HSI 32 MHz and LSI 128 kHz), and support for external crystals; power-saving STOP and IDLE modes for low-power designs.
• System Reliability  On-chip Power-On Reset (POR), Low Voltage Reset (LVR) with multiple detection levels, Low Voltage Indicator (LVI), and Watch Dog Timer (WDT) for robust system supervision.
• Package & Temperature  Surface-mount 44-LQFP (10 × 10 mm, 0.8 mm pitch) and specified operation from −40 °C to +85 °C.

Typical Applications

• Home Appliances  Control user interfaces, motor drive timing and sensor inputs for compact appliance controllers.
• Consumer Electronics  Manage display, input scanning and analog sensor readout where an 8-bit MCU with integrated ADC and multiple serial ports is required.
• Industrial Control  Implement process control, timing, watchdog supervision and multi-channel ADC sampling in embedded controllers operating across wide temperature ranges.
• Battery-Powered & Low-Power Devices  Leverage wide VCC range and STOP/IDLE power-saving modes for portable electronics and energy-conscious designs.

Unique Advantages

• Highly integrated peripheral set: On-chip ADC (12-bit, 16 channels), multiple timers/PWM channels, and serial interfaces reduce external components and simplify BOM.
• Flexible memory and reprogramming: 64 Kbytes Flash with in-system programming and specified endurance supports field updates and iterative development.
• Wide voltage and clock flexibility: Operates from 1.8–5.5 V with both internal RC and external crystal clock options to match diverse power and timing requirements.
• Robust system supervision: Built-in POR, LVR/LVI and WDT provide multiple layers of reset and fault detection for increased runtime reliability.
• Compact, manufacturable package: 44-LQFP (10 × 10 mm) surface-mount package with 0.8 mm pitch supports automated assembly in space-constrained designs.
• Industrial temperature operation: Rated to operate from −40 °C to +85 °C for demanding environmental conditions.
