The analog front end includes 11 channels of 12-bit ADC and 4 channels of 12-bit DAC, letting it handle sensor acquisition and analog output directly. Connectivity covers CANbus, I²C, SPI, UART/USART, USB, and SAI — suitable for industrial fieldbus and human-machine interface nodes. The 512 KB Flash (512K x 8) is sized for applications like motor-control firmware with sensorless observer algorithms, or a USB stack with multiple endpoints. The 112 KB RAM (112K x 8) supports double-buffered ADC data and a modest RTOS heap. The ROHS3 compliance is confirmed. ## 32-UFQFN exposed pad — layout and thermal notes The package is a 32-lead UFQFN with an exposed pad (supplier device package 32-UFQFPN, 5x5 mm). The 26 I/O count leaves six pins for supply and ground.","metaTitle":"STM32G4A1KEU6 ARM Cortex-M4F MCU, 170 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32G4A1KEU6 32-bit MCU with ARM Cortex-M4F core at 170 MHz, 512 KB Flash, 112 KB RAM, 11x12b ADC, 4x12b DAC, 32-UFQFN.
