| Parameter | STM32F030C8T6 | APM32F030C8T6 | Engineering note |
|---|---|---|---|
| CPU core | Arm Cortex-M0 at 48 MHz | Arm Cortex-M0+ at 48 MHz | Validate startup code, toolchain configuration, debug sequences and any core-specific timing assumptions. |
| Supply voltage range | 2.4 V to 3.6 V | 2.0 V to 3.6 V | The target has a wider operating range. |
| Alternate-function mapping | STM32 GPIO alternate-function indices and device headers | APM32 GPIO alternate-function indices and Geehy device headers | Several GPIOs expose the same signal on a different AF index (for example PA0, PA1, PA2 and PA3), so firmware register configuration and the board-support package must be ported and revalidated. |
| External ADC channels | 10 external channels on STM32F030C8T6 | 16 external channels on APM32F030C8T6 | The target offers additional analog inputs. |
Accepted as a functional equivalent after primary-datasheet comparison, not as a code-compatible drop-in: both exact order codes are LQFP48, 64 KB Flash, 8 KB SRAM, 48 MHz, -40 to +85 °C, with the same physical GPIO names and supply/SWD pin positions. Both expose 7 timers, 2 USARTs, 2 SPI, 2 I2C, 5 DMA channels and one 12-bit ADC. The Cortex-M0/M0+ core and GPIO alternate-function mapping differ, so existing firmware and pin-mux tables require porting and board-level validation.
