TXS0206A - TXS0206A MMC, SD Card, Memory Stick™ Voltage-Translation Transceiver

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.
