The closest documented alternative to STM32F103CGT6 is Artery AT32F403ACGT7, graded PIN (package- and pinout-compatible candidate that needs firmware work, high confidence). Key difference to review first: Max clock 240MHz vs 72MHz (review peripheral clock configuration). Every match is an engineering-review candidate, not an unqualified drop-in claim.
Grading methodology: how grades and evidence classes work.
Differences for the other candidates are listed per match below.
| SPEC | AT32F403ACGT7 Artery · PIN |
|---|---|
| Speed (MHz) | 240 |
| SRAM | 96+128 |
| Package | LQFP48 7x7 mm |
| Temp Range | 40°C to +105°C |
Documented differences: Max clock 240MHz vs 72MHz (review peripheral clock configuration); Firmware port required: most registers compatible but not all; official migration guide + device pack provided; Operating temperature -40~105°C (T7) wider than ST's -40~85°C (T6). Review each against your application before committing.
AT32F403ACGT7 is a PIN-graded engineering-review candidate (package- and pinout-compatible candidate that needs firmware work). At minimum, review: Max clock 240MHz vs 72MHz (review peripheral clock configuration). Production use requires validation on your board.
P2P is a documented drop-in candidate, PIN keeps the package and pinout but needs firmware work, and FUNC is functionally similar but may require a board or BOM change.
