|---|---|---|---|
| Flash | 128K | 256K | 256K |
| RAM | 32K | 64K | 96K |
| Pack | lqfp48 | lqfp48 | lqfp64 |
- AIR32F103, MH32F103A and MH2103A series
- Supplied by different vendors, but they are the same from the software aspect of view.
- The electrical characteristics might be different, be careful when replacing them in production.
- Unlock the hidden 97K RAM
- It's very likely the AIR32F103CBT6 you bought have 97K RAM - Hedley Rainnie's blog
- This also apply to AIR32F103CCT6 and AIR32F103RPT6.
- The hidden RAM can be unlocked by special registers, the hack has been integrated into startup_air32f10x.s. Thanks to @deividAlfa.
