Level Shifter for SD Memory Cards: T3GF3WBG

In most cases, external memory cards are used to store music, video, and other data on mobile phones. However, as the shift to using lower voltages in mobile phones due to the CPUs they use providing higher performance with lower power consumption, the importance of electrical conversion between card and phone has been increasing. In addition, as mobile phones themselves are becoming smaller, it is required that their components become even smaller and more integrated. In light of the above, an ultra-compact voltage level translation IC, T3GE9WBG, is available that, in addition to signal level translation functionality, incorporates peripheral components - namely, an ESD protection device, an EMI filter, and an LDO - and employs WCSP. However, now a new IC, T3GF3WBG, has been developed that is compliant with advanced SD communications standards.
T3GF3WBG is a level shifter that is compliant with the standards for high-speed interfaces, SDR12, SDR25, and DDR50, in SD Memory Card Specification Version 3.0. As it is also compliant with DS mode, which has a 3.3 V signal voltage, and HS mode, T3GF3WBG is also compatible with SD Memory Card Specification Version 2.0 as used by conventional SD interfaces. The ultra-compact WCSP25 package is used, contributing to reductions in mounting area.
