SDIO Slave Controller

Rs0.00

Overview

SDIO Slave controller facilitates the design of SDIO cards and reduces the development time. By using this IP core, customers no longer need to spend time on handling the SD bus protocol since such function is provided by the core

Benefits Highlights

Helps in designing in SDIO cards
Can be used as a bridge core of SDIO to UART

Controller handles SD bus protocol on the card interface and provides simplified interface to user logic
Controller handle all the housekeeping tasks by itself without user logic intervention
