| Parameter | STM32F407ZET6 | GD32F407ZET6 | Engineering note |
|---|---|---|---|
| Package and exact order code | STM32F407ZET6: LQFP144, 512 KB Flash, 192 KB SRAM, 168 MHz, -40 C to +85 C | GD32F407ZET6: LQFP144, 512 KB Flash, 192 KB SRAM, 168 MHz, -40 C to +85 C | The exact order codes correspond in core, memory capacity, package, maximum clock and temperature. The reviewed LQFP144 tables show the same physical pin order; land pattern and assembly still require independent release checks. |
| Operating supply voltage | Recommended 1.8 V to 3.6 V | Recommended 2.6 V to 3.6 V | The target minimum recommended supply is 0.8 V higher. A supply rail or transient that can fall below 2.6 V is not covered by the target recommendation and requires a separately validated design. |
| VCAP pins | VCAP_1 and VCAP_2 are on LQFP144 pins 71 and 106 with external capacitors | The corresponding LQFP144 pins are marked NC | The ST external VCAP capacitors and internal-regulator assumptions cannot be carried over. Remove or re-evaluate those components and use the target reference design. This is a hardware-design blocker for a direct copy of the ST schematic. |
| Pin functions and firmware | STM32F407 pin AF mapping, registers, clock tree, peripheral numbering, boot flow and STM32 firmware ecosystem | Physically corresponding GD32F407 pins with different AF/register behavior, clock configuration, peripheral implementation, drivers and tools | Pin-to-pin means the reviewed main-function sequence corresponds. It does not imply binary or source compatibility. Every used peripheral, startup path, linker layout, USB/Ethernet function and analog configuration must be migrated and validated. |
FAE documentary review accepted for the exact ST STM32F407ZET6 and GigaDevice GD32F407ZET6 order codes. Both are Cortex-M4 devices with 512 KB Flash, 192 KB SRAM, 168 MHz maximum clock, LQFP144 package and -40 C to +85 C rating. The target raises the recommended minimum supply from 1.8 V to 2.6 V and marks the pin positions corresponding to ST VCAP_1/VCAP_2 as NC, so the ST regulator-capacitor network cannot be copied. Registers, clocks, peripheral identifiers, firmware and tools differ. Document review only; no bench, temperature-cycle, EMC, reliability or production qualification was performed.
