Realtek RTS5138
The RTS5138 is an ultimate throughput USB 2.0 compliant card reader controller that integrates USB 2.0 Transceiver, MCU, SIE, regulators and memory card access units into a single chip. The RTS5138 can support Memory Stick TM, Memory Stick Pro TM, Memory Stick PRO-HG Duo TM, Secure Digital TM, Multi-Media Card TM and xD-Picture Card TM, but only 1-LUN configuration, i.e. The RTS5138 integrates 3.3V-to-1.8V regulator, clock generation circuitry and MOSFET, and could dramatically reduce the system BOM cost.DESCRIPTION
