A31G314MLN

The A31G314MLN is a 32-bit microcontroller from Abov’s A31G31x series built around an ARM Cortex-M0+ core for main-controller applications in appliances. It combines a 48 MHz Cortex-M0+ CPU with up to 128 Kbytes of on-chip Flash and 16 Kbytes of SRAM, plus a broad set of peripherals and serial interfaces to support sensor connectivity, motor control and user-interface functions.

Key Features

• Core ARM Cortex-M0+ 32-bit core running at 48 MHz for deterministic embedded control.
• Memory 128 Kbytes of on-chip Flash program memory and 16 Kbytes of SRAM for application code and runtime data.
• Power Supply & Temperature Wide supply range of 1.8–5.5 V and operating temperature from −40 to 85 °C for robust appliance environments.
• Timers & Motor Control 3-phase PWM (16-bit), seven 16-bit timers and two 32-bit timers enable precise motor and timing control.
• Analog 12-bit ADC with 14 channels and a 12-bit DAC, plus two comparators and CRC support for signal conditioning and integrity checks.
• Display & UI Integrated LCD driver (39×8) and LED driver / high-current port plus 24-channel touch-key support for user interfaces.
• Connectivity Multiple serial interfaces including I2C, UART and USART to connect sensors, peripherals and communication modules.
• System & DMA 4-channel DMA, PLL, watchdog timer and other system peripherals to support real-time operation and reliability.
• I/O & Package Up to 74 GPIOs in an 80-LQFP package (12x12-0.5 mm) for dense board integration and flexible pin assignments.

Typical Applications

• Home Appliances Main controller for consumer appliances where sensor interfacing, motor control and user displays are required.
• Motor Control 3-phase PWM and multiple timers support motor drive control and precise speed/torque management.
• User Interface Control Integrated LCD driver, LED driver and touch-key channels enable compact, feature-rich front-panel designs.
• Sensor Hubs Multi-channel ADC, DAC and serial interfaces (I2C, UART/USART) allow centralized sensor data acquisition and preprocessing.

Unique Advantages

• Balanced performance and integration: 48 MHz Cortex-M0+ with 128 Kbyte Flash and 16 Kbyte SRAM provides ample compute and memory for appliance control firmware.
• Comprehensive analog and motor peripherals: 12-bit ADC (14 channels), 12-bit DAC, comparators and 3-phase 16-bit PWM reduce external component count for motor and analog systems.
• Rich human‑machine interface support: On-chip LCD driver, LED driver and 24-channel touch-key capability simplify UI designs and speed time-to-market.
• Flexible I/O and packaging: 74 GPIOs in an 80-LQFP package allow dense feature sets and multiple board layout options.
• Robust system features: DMA, CRC, PLL and watchdog timer support reliable, real-time embedded operation in appliance environments.
