The Realtek Ameba D are dual core (KM0/KM4) microprocessors with WIFI and Bluetooth.
Flash Banks
Internal Flash
| Flash Bank | Base address | Size | J-Link Support | Limitations |
|---|---|---|---|---|
| QSPI | 0x08000000 | 4 MB |  |
only for RTL872xDF devices |
QSPI Flash
QSPI flash programming requires special handling compared to internal flash. For more information about this, please see the QSPI Flash Programming Support article.
| Device | Base address | Maximum size | Supported pin configuration |
|---|---|---|---|
| RTL872xCS RTL872xDN RTL872xDM |

|
Device Specific Handling
Reset
- The devices uses normal Cortex-M reset, no special handling necessary, like described here.
Multi-Core Support
Flash programming is done by KM0 core (Cortex-M23).
