A31G226MLN

The Abov A31G226MLN is a 32-bit microcontroller based on an ARM Cortex-M0+ core, optimized as a main controller for a range of appliances and embedded systems. It combines a high-speed 48 MHz core with a large on-chip memory footprint and a broad set of integrated peripherals to support sensor interfacing, motor/power control and display-driven user interfaces.

With 256 KB Flash, 32 KB data flash and 20 KB SRAM, plus extensive analog and timing resources, the A31G226MLN targets designs that require integration, reliable operation and flexible I/O in a single LQFP80 package.

Key Features

• Core  ARM Cortex-M0+ 32-bit core running up to 48 MHz for efficient control and deterministic embedded processing.
• Memory  256 KB code Flash with memory bank swap and read-protection options, plus 32 KB data Flash and 20 KB SRAM for code, data logging and secure storage.
• Clock & Power Management  Multiple clock domains and power modes (Run, Sleep, Deep-Sleep) with low-voltage detection and clock monitoring to optimize power and reliability across operating conditions.
• Analog and Data Conversion  12-bit A/D converter (up to 1.0 Msps) with up to 18 channels and a 12-bit D/A output for precise sensor acquisition and analog output control.
• Timers, PWM & DMA  Rich timing resources including seven 16-bit timers, two 32-bit timers, 3-channel 16-bit PWM (3-phase complementary PWM generators) and an 8-channel DMA controller for low-CPU data movement.
• Connectivity  Multiple serial interfaces: 3 I2C channels, 2 SPI channels and a combination of UART/USART channels (2 UARTs, 4 USARTs) for sensor, actuator and subsystem communication.
• Display & Output Drivers  Integrated LCD driver (configurable COM × SEG for up to 8×37 / 3×42 on 80-pin devices) and high-current sink output ports for direct drive of indicators and front-panel elements.
• System Reliability & Safety  Watchdog and watch timer, CRC generator (7/8/16/32-bit), internal temperature sensor and IEC60730 qualification for appliance safety-related applications.
• Package & I/O  Available in an 80‑pin LQFP (12×12 mm, 0.50 mm pitch) with up to 75 I/O ports to accommodate complex system interfaces.
• Operating Conditions  Wide supply range from 1.8 V to 5.5 V and operation from −40 °C to +85 °C for robust performance across typical appliance and industrial environments.

Typical Applications

• Home Appliances  Central control for washing machines, refrigerators and other appliances where integrated ADCs, PWM and LCD/LED drivers simplify user interface and motor control.
• Motor & Power Control  3-phase complementary PWM, multiple timers and DMA support enable efficient motor drive control and real-time power management.
• Sensor Hubs & Environmental Controls  Multi-channel 12-bit ADC and multiple I2C/SPI interfaces provide direct connectivity to temperature, humidity and pressure sensors for HVAC and building automation.
• Human-Machine Interfaces (HMI)  On-chip LCD driver, high-current output ports and abundant GPIOs streamline display and input handling for consumer and industrial HMIs.

Unique Advantages

• Highly integrated memory configuration: 256 KB Flash, 32 KB data Flash and 20 KB SRAM reduce external memory needs and simplify BOM.
• Comprehensive analog front end: 12-bit A/D (18 channels) and 12-bit D/A provide accurate sensor acquisition and analog control without adding external converters.
• Flexible timing and real-time control: Multiple 16-bit and 32-bit timers, 3-channel PWM and an 8-channel DMA offload timing and data movement for deterministic control tasks.
• Display and driver support: Integrated LCD driver and high-current sink outputs enable compact user interface implementations with fewer external components.
• Wide voltage and temperature tolerance: 1.8–5.5 V supply range and −40 °C to +85 °C operating range support diverse system power architectures and environmental conditions.
• Safety and system integrity: IEC60730 qualification, CRC engine, watchdog and voltage monitoring help meet appliance safety and reliability requirements.
