Product details

512 KB Flash, 24 MHz Cortex-M3 — what this MCU delivers

The STM32F100RET7BTR integrates a 16-channel 12-bit ADC and a dual 12-bit DAC for sensor acquisition and analog output.

Industrial temperature grade — why it matters for the BOM

For a motor drive or a base-station power module, that saves a qualification cycle and avoids a separate high-temp variant on the AVL.

Memory and peripheral fit for mid-complexity designs

The 51 I/Os in the 64-LQFP package give sufficient GPIO for parallel sensor arrays or a local display interface. The integrated 12-bit ADC and DAC reduce external analog count, which simplifies the PCB layout and cuts procurement lines.
