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