| Parameter | STM32F407ZGT6 | GD32F407ZGT6 | Engineering note |
|---|---|---|---|
| Package and pin sequence | STM32F407ZGT6: LQFP144, 20 x 20 mm | GD32F407ZGT6: LQFP144, 20 x 20 mm, green industrial | The exact order codes are both LQFP144. Table-based comparison found the same physical pin names on 1 through 144 except ST VCAP_1/VCAP_2 at pins 71/106, which the GD table marks NC. |
| External VCAP pins | VCAP_1 on pin 71 and VCAP_2 on pin 106 | Pins 71 and 106 are marked NC | Remove or independently assess ST-oriented VCAP capacitors and regulator/reset circuitry. The physical land positions align, but the electrical function of these pins is not identical. |
| Flash organization | 1024 KB contiguous code Flash in the ZG order code | 1024 KB total: 512 KB code area plus 512 KB data area | Total Flash capacity matches, but the target's code/data partition differs from the source. Firmware-linking, code execution above 512 KB, boot behavior and data-flash use require target-specific review. |
| Operating supply voltage | 1.8 V to 3.6 V | 2.6 V to 3.6 V | The target minimum supply is 0.8 V higher. Designs operating below 2.6 V are not eligible for this replacement. |
| Peripheral identifiers and software | STM32 TIMx, SPIx, I2Cx, USARTx register and firmware ecosystem | GD32 TIMERx, SPIx, I2Cx, USARTx register and firmware ecosystem | The package and SRAM capacity correspond, but peripheral numbering, registers, clock setup, USB/Ethernet behavior, drivers and tool support differ. |
FAE documentary review accepted for the exact STM32F407ZGT6 and GD32F407ZGT6 order codes. Both are 1 MB Flash-class, 192 KB SRAM, 114-GPIO, 168 MHz LQFP144 Cortex-M4 MCUs rated -40 C to +85 C. GD organizes the 1 MB as 512 KB code plus 512 KB data area, so code execution and Flash addressing need target-specific review. The complete pin table matches except ST VCAP_1/VCAP_2 at pins 71/106, where GD marks NC, and the target minimum supply rises to 2.6 V. Document review only; not bench, temperature-cycle, EMC, reliability or production qualified.
