Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

The host controllers can be equal to, greater Low On Capacitance: 6pF Typical than, or less than peripheral card supply with minimal Low Power Consumption: 2A Maximum power consumption. This configuration enables dual host CMD, CLK, and D 3:0 signals to be multiplexed to Supports Secure Digital (SD), Secure Digital I/O a common peripheral. (SDIO), and Multimedia Card (MMC) Specifications The architecture includes the necessary bi-directional Supports 1-Bit / 4-Bit Host Controllers (V =1.65V DDH1/H2 data and command transfer capability for single high- to 3.6V) Communicating with voltage cards or dual-voltage supply cards. The clock High-Voltage (2.7-3.6V) and Dual-Voltage Cards path is a uni-directional buffer. (1.65-1.95V, 2.7-3.6V) Typical applications involve switching in portables and - V =1.65 to 3.6V, V =1.65 to 3.6V DDC DDH1/H2 consumer applications: cell phones, digital cameras, 24-Lead MLP and UMLP Packages home theater monitors, set-top boxes, and notebooks.
