Identity and memory
The current GD32E103xx datasheet maps the CBT6 code to the LQFP48, 128 KB flash and 32 KB SRAM configuration. Supply, temperature and peripheral limits must be read from that revision for the exact code.
Exact manufacturer part number
GD32E103CBT6 MCU – 120MHz, 128KB, LQFP48, RFQ
GD32E103CBT6 identifies a 120 MHz Arm Cortex-M4 GD32E103 member with 128 KB flash, 32 KB SRAM and an LQFP48 package. Quote the complete code, not a shortened family name.

Buyer and engineer answers
What must be established before ordering
Statements below are scoped to the named manufacturer source. Commercial availability is deliberately separate.
Ordering and packing
GD32E103CBT6 is the requested manufacturer part number. Tray or reel availability, date code and minimum order are commercial facts confirmed on the quotation.
Migration boundary
Cortex core and a familiar package do not establish drop-in compatibility with STM32F103CBT6. Review pin functions, peripherals, clocks, boot behavior and the GigaDevice SDK before migration.
Publication safeguard
The claim boundary travels with the page.
Never describe this part as zero-change or drop-in compatible. A migration comparison must cover pinout, peripherals, clocks, boot behavior and SDK impact.

Procurement FAQ
Questions this exact page answers
Compatibility answers remain conditional where the source evidence does not establish a direct replacement.
Is GD32E103CBT6 pin-compatible with STM32F103CBT6?
Do not assume it. Compare the exact pin tables, alternate functions, electrical limits and board use before approving a substitution.
What firmware changes are required?
That depends on clocks, peripherals, startup code, interrupt use and SDK dependencies; validate the project against GigaDevice documentation and hardware.
Is tray or reel packing available?
Packing and quantity are confirmed for the offered lot; the page does not infer them from the device name.
