3 Description
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. VCCA as well as VCCB 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, settop
boxes, etc. Low static power consumption and
small package size make the TXS0206A an ideal
choice for these applications.
