48 MHz Cortex-M0 with 32 KB flash — what fits in that envelope
The STM32F038C6T7 runs an ARM Cortex-M0 core at 48 MHz, with 32 KB of flash and 4 KB of SRAM — a tight memory budget that suits a single control loop, a sensor-fusion state machine, or a simple communication bridge, but not a GUI stack or data logger.
Industrial temp grade and 48-LQFP — bench and panel reality
The 48-LQFP (7x7 mm) is a hand-solderable, inspectable footprint — no BGA reflow, no X-ray inspection. A rework tech can swap it with a hot-air station and a pair of tweezers. Ten 12-bit ADC channels cover multi-sensor analog front-ends without an external multiplexer. The peripheral set — DMA, I²S, PWM, UART/USART, SPI, I²C — handles motor-control feedback, audio sample streaming, or a sensor hub with one chip.
RoHS3 compliant. The base product number is STM32F038; the suffix C6T7 encodes the 48-LQFP package and the industrial temperature grade.
