NS1083AD is a high-performance USB 3.0 Flash Card controller designed specifically for MFi applications. It is fully in compliance with MFi Specification, supporting iAP2 protocols and EA Native Transport, Device Powered, and App Launch. It also supports MFi USBRole Switch and USB OTG. NS1083AD is compatible with USB 3.1 Gen1 (5Gbps), USB Hi-Speed, and Full-Speed. On one side,
NS1083AD connects with up to two USB interfaces such as Type-A, Type-C, and Apple Lightning Interface. On the other side, it connects with up to two 4-bit flash media cards, such as Secure Digital (SD) and microSD (T-Flash); or one 8-bit flash card such as Embedded-MultiMediaCard (eMMC).
Two low-power USB 2.0 PHY specifically optimized for MFi applications. Each USB 2.0 PHY transceiver can be configured to either USB 2.0/1.1 Host or USB 2.0/1.1 device. An integrated USB 2.0 MUX enables data selection from one of the USB 2.0 transceivers.
Support charging mode detection compatible with specifications from Apple and USB BC1.2. During data transfer, an iDevice can be simultaneously charged from a USB port or a power adapter at the maximum supported charging current.
Capable of operating SD card at different frequencies for Read and Write independently. This patentedtechnology guarantees the best performance of Read and Write while meeting the MFi requirement of the maximum current limit.
