| 9 | +description: |
| 10 | + The Microchip PIC32 family of microcontrollers (MCUs) includes models with |
| 11 | + Secure Digital Host Controller Interface (SDHCI) controllers, allowing them |
| 12 | + to interface with Secure Digital (SD) cards. This interface is used for reading, |
| 13 | + writing, and managing data on SD cards, enabling storage and data transfer |
| 14 | + capabilities in embedded systems. |
