STM32G030C8T6

The STM32G030C8T6 is a mainstream value-line Arm Cortex-M0+ 32-bit RISC microcontroller from STMicroelectronics in LQFP-48 package, featuring 64 KB Flash, 8 KB SRAM, 64 MHz CPU, 2x I2C, 2x SPI, 2x USART, 12-bit ADC with 19 channels, RTC, and multiple timers. Operating from 2.0 V to 3.6 V over -40°C to 85°C with Sleep, Stop and Standby low-power modes.

The STM32G030C8T6 is based on the Arm Cortex-M0+ 32-bit RISC processor core running at up to 64 MHz. It uses a Harvard architecture with separate instruction and data buses for efficient execution. The embedded Flash memory stores program code while SRAM with hardware parity check provides data storage. A memory protection unit (MPU) controls access permissions to memory regions. The 5-channel DMA controller with flexible mapping offloads data transfers from the CPU. Multiple clock sources (4-48 MHz crystal, 32 kHz crystal, internal 16 MHz RC with PLL, internal 32 kHz RC) provide flexible clock management. Peripherals are interconnected via a bus matrix, and a DMAMUX routes DMA requests. The power management controller supports Sleep, Stop and Standby modes, with VBAT input preserving RTC and backup register contents during main power loss. Debug is supported via Serial Wire Debug (SWD) interface.
