STM32G431CBU6 - ST

STM32G431CBU6 is a high-performance 32-bit microcontroller from STMicroelectronics, based on the Arm Cortex-M4 core with FPU (Floating Point Unit) running at up to 170MHz. It features 128KB of Flash memory with ECC support and 32KB of SRAM, providing robust storage for complex real-time control applications. This device integrates a rich set of analog peripherals including three operational amplifiers (OPAMPs) with programmable gain, four ultra-fast rail-to-rail comparators, two 12-bit ADCs (up to 18 channels, 0.25µs conversion time), and four 12-bit DAC channels. Math accelerators (CORDIC for trigonometric functions and FMAC for filter mathematics) enhance computational efficiency for motor control and digital power applications. Communication interfaces include CAN FD, three I2C, four USARTs, three SPIs (two with I2S), and USB 2.0 Full Speed. Housed in a compact UFQFPN-48 (7x7mm) package with 42 I/O pins, the STM32G431CBU6 operates from 1.71V to 3.6V. It is ideal for motor drives, digital power supplies, industrial automation, robotics, medical devices, and advanced sensing applications requiring high analog integration and real-time performance.
