DESCRIPTION/ORDERING INFORMATION

The TXS0206 is a level shifter for interfacing microprocessors with MultiMediaCards (MMCs), secure digital (SD)

cards, and Memory Stick™ cards. It includes a high-speed level translator along with ESD protection and EMI

filtering circuitry.

The voltage-level translator has two supply voltage pins. VCCA as well as VCCB can be operated over the full

range of 1.1 V to 3.6 V. The TXS0206 enables system designers to easily interface applications processors or

digital basebands to memory cards and SDIO peripherals operating at a different I/O voltage level.

Memory card standards recommend high-ESD protection for devices that connect directly to the external memory

card. To meet this need, the TXS0206 incorporates ±8-kV Contact Discharge protection on the card side.

The TXS0206 is offered in a 20-bump wafer chip scale package (WCSP). This package has dimensions of

1.96 mm × 1.56 mm, with a 0.4-mm ball pitch for effective board-space savings. Memory cards are widely used

in mobile phones, PDAs, digital cameras, personal media players, camcorders, set-top boxes, etc. Low static

power consumption and small package size make the TXS0206 an ideal choice for these applications.
