DESCRIPTION/ORDERING INFORMATION
The TXS0206A is a level shifter for interfacing microprocessors with MultiMediaCards (MMCs), secure digital
(SD) cards, and Memory Stick™ cards.
The voltage-level translator has two supply voltage pins. V_CCA as well as V_CCB can be operated over the full
range of 1.1 V to 3.6 V. The TXS0206A 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.
The TXS0206A 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 TXS0206A an ideal choice for these applications.
