A31G313SNN

The A31G313SNN is a 32-bit microcontroller from Abov's A31G31x series, built around an ARM Cortex-M0+ core. It is designed for main controller roles in a wide range of appliances, combining a compact memory footprint with a broad set of embedded peripherals.

Operating at up to 48 MHz, the device pairs 64 Kbytes of Flash and 16 Kbytes of RAM with integrated analog, timer and interface blocks to support motor control, sensor interfacing and user interface functions while running from a flexible 1.8–5.5 V supply and an extended −40 to 85 °C temperature range.

Key Features

• Core & Performance ARM Cortex-M0+ 32-bit core running at up to 48 MHz for deterministic embedded control.
• Memory 64 Kbytes of on-chip Flash (program memory) and 16 Kbytes of SRAM for application code and runtime data. The A31G31x family also includes alternate Flash size options for scalability.
• Power & Clock Wide VDD range of 1.8–5.5 V and support for both internal and external oscillators to fit varied system power architectures.
• Timers & Motor Control Integrated 3-phase 16-bit PWM and multiple 16-bit and 32-bit timers to support motor drive and precise timing tasks.
• Analog & Data Conversion 12-bit ADC and 12-bit DAC for accurate sensor reading and analog output generation.
• Interfaces & Connectivity On-chip I2C, SPI and UART/USART interfaces for system interfacing.
• System & Reliability CRC, DMA and a Watch Dog Timer are included to assist in data integrity, efficient data movement and system reliability.
• Display & Indicator Support Integrated LCD driver and LED driver blocks for user interface and status indication without large external components.
• IO & Package 39 general-purpose I/O lines in a surface-mount 44‑LQFP package to suit compact PCB designs.
• Operating Range Specified for industrial temperature operation from −40 to 85 °C.

Typical Applications

• Appliance Main Controllers  Designed for use as the principal controller in household and commercial appliances where mixed-signal control and user interfaces are required.
• Motor Control  3-phase PWM and versatile timers enable control of brushless or multi-phase motors and drive systems.
• Sensor Front-Ends  12-bit ADC and serial interfaces (I2C, UART/USART) simplify direct sensor interfacing and data acquisition tasks.
• User Interface Control  Built-in LCD and LED drivers streamline implementation of on-device displays and indicators.

Unique Advantages

• Integrated mixed-signal peripherals: ADC, DAC, LCD and LED drivers reduce external component count and simplify board design.
• Motor-capable timer suite: 3-phase 16-bit PWM plus 16/32-bit timers support precise motor drive and timing control without heavy external logic.
• Flexible power and clocking: 1.8–5.5 V operation with internal and external oscillator options for adaptable system integration.
• Compact I/O and package: 39 I/O lines in a surface-mount 44‑LQFP package balance capability with a small PCB footprint.
• Robust operating range: Specified −40 to 85 °C to meet common appliance and industrial thermal requirements.
• Family scalability: Part of the A31G31x series, which offers multiple Flash size options to match memory requirements across product variants.
