The TWL1200 is an 19-bit voltage translator specifically designed to seamlessly bridge the 1.8-V/2.6-V digital-switching compatibility gap between 2.6-V baseband and the TI Wi-Link-6 (WL1271/3). It is optimized for SDIO, UART, and audio functions. The TWL1200 has two supply-voltage pins, VCCA and VCCB, that can be operated over the full range of 1.1 V to 3.6 V. The TWL1200 enables system designers to easily interface applications processors or digital basebands to peripherals operating at a different I/O voltage levels, such as the TI Wi-Link-6 (WL1271/3) or other SDIO/memory cards. The TWL1200 is offered in both 48-ball 0.5-mm ball grid array (BGA) and 49-bump 0.4-mm wafer chip scale package (WCSP) packages. Low static power consumption and small package size make the TWL1200 an ideal choice for mobile-phone applications.
