A31G213GR

The A31G213GR is a 32‑bit microcontroller from Abov designed for main controller applications in a broad range of appliances and consumer-electronics products. It integrates an ARM Cortex‑M0+ core running up to 48 MHz with large on‑chip Flash and a rich set of peripherals to support motor control, sensor interfacing, and user‑interface tasks.

With multi‑interface connectivity and mixed‑signal peripherals, the A31G213GR targets compact systems that require performance, peripheral integration, and flexible power/clock operation across a wide supply range and extended temperature window.

Key Features

• Core and Performance ARM Cortex‑M0+ 32‑bit core with maximum operating frequency up to 48 MHz, delivering deterministic control for embedded appliance applications.
• Memory 64 Kbytes of on‑chip FLASH for program storage and 6 Kbytes of SRAM for runtime data and stack.
• Power and Clock Wide operating voltage range from 1.8 V to 5.5 V and support for internal and external oscillators, with PLL and low‑speed internal (LSI) clock options for flexible power/clock management.
• Timers and PWM Multiple timers including 16‑bit and 32‑bit general purpose timers, watchdog timer, and dedicated PWM resources: 3‑phase 16‑bit PWM plus up to six 16‑bit PWM channels on the 28‑TSSOP variant for motor and power control tasks.
• Analog and Data Converters 12‑bit ADC and 5‑bit DAC; on the 28‑TSSOP A31G213GR variant the ADC is implemented with 6 input channels, enabling precise sensor measurement and simple control loops.
• Connectivity Comprehensive serial interfaces including I2C, SPI and UART/USART, enabling robust communication with sensors, peripherals, and human‑interface components. The GR variant provides 2 UARTs, 1 USART, 1 SPI and 2 I2C instances.
• System Reliability and Support Nested Vector Interrupt Controller (NVIC) with 32 interrupt sources, CRC (CRC‑CCITT/CRC‑16), DMA, and SWD debug for development and reliable operation.
• User Interface and Special Functions Integrated LED driver and capacitive touch key support to simplify UI implementation; LED driver and touch resources available across the A31G21x family.
• Package and Environmental 28‑pin TSSOP (9.7 × 4.4 mm, 0.65 mm pitch) surface‑mount package with 24 available I/O pins on the GR variant, and operating temperature up to 105 °C for industrial grade applications.

Typical Applications

• Home Appliances — Main controller for appliances such as fans, pumps, and small motors where integrated PWM, ADC and timers enable efficient motor and power control.
• Consumer Electronics — System controller for user interfaces and sensor aggregation, leveraging capacitive touch, LED driver, and multiple serial interfaces.
• Motor and Power Control — 3‑phase 16‑bit PWM and multiple 16‑bit PWM channels support compact motor control schemes and power conversion tasks.
• Sensor Hubs — Multi‑interface connectivity (I2C, SPI, UART/USART) and 12‑bit ADC provide a compact platform for aggregating and digitizing sensor data.

Unique Advantages

• Highly integrated peripheral set: On‑chip ADC, DAC, PWM, LED driver, touch key support, CRC, DMA and multiple timers reduce external component count and simplify BOM.
• Flexible power and clocking: 1.8–5.5 V supply range with internal/external oscillators and PLL support enables designs across battery and mains‑powered topologies.
• Compact package with ample I/O: 28‑TSSOP footprint (9.7 × 4.4 mm) with 24 I/O pins provides space‑constrained designs a full feature set without sacrificing connectivity.
• Real‑world operating range: Industrial‑grade temperature support to +105 °C and robust reset/clock management for appliance and industrial environments.
• Developer‑friendly features: SWD debug interface and NVIC with 32 interrupt sources accelerate development and debugging of embedded applications.
