Design notes

Use the rating in context

Peripheral counts vary by package within the GD32E103 family; this page uses the Cx/LQFP48 column and must not inherit LQFP64 or LQFP100 counts.

The datasheet removed CAN in revision history; this exact page does not claim an integrated CAN controller.

Absolute maximum ratings are stress limits. Clock, supply and temperature values shown here are selected from the documented operating and ordering conditions.

Quotation and fulfillment

What is confirmed before an order

Commercial facts belong to the quoted lot. The catalog does not invent live stock, price, date code or lead time.

Exact-part check

Manufacturer, full suffix, package, quantity and requested documentation are captured in the RFQ.

Lot-level quotation

Price, available quantity, date code, condition and lead time are written into the quotation when confirmed.

Inspection request

Label, marking, packing and traceability requirements can be specified before shipment.

Shipping and payment

Shipping method, Incoterm and available payment route are agreed in the commercial offer.

Technical and ordering FAQ

Questions buyers ask about GD32E103CBT6

Answers distinguish the IC itself from assembled modules and keep absolute limits separate from normal operating conditions.

How much memory does GD32E103CBT6 contain?

The CB density code is listed with 128 kB of flash and 32 kB of SRAM.

Which package does GD32E103CBT6 use?

The exact order code is listed in a 48-pin LQFP package.

What is the maximum core clock?

The GD32E103 Cortex-M4 core is specified to operate at up to 120 MHz.

Does GD32E103CBT6 include CAN?

The reviewed Rev 2.1 document does not list CAN and records its removal in the revision history. A design needing CAN should not assume it is present.

What temperature grade does the T6 suffix identify?

The manufacturer ordering table lists grade 6 for -40 °C to +85 °C operation.

Catalog relationships
