SD/MMC voltage level translator eliminates more than 10 discrete components

Dallas, Tex.—Engineers can now bridge the gap between two disparate voltage nodes while maintaining digital switching compatibility by using a tiny, highly integrated Secure Digital (SD)/MultiMedia Card (MMC) level shifter from Texas Instruments (TI). The translator's auto-direction circuitry simplifies board design by eliminating the need for customers to program a General Purpose Input/Output (GPIO) on a processor for direction control and thereby reduces the number of required pins. Highly integrated features of the TXS0206, packaged in a 2 mm x 1.6 mm wafer chip-scale package (WCSP), eliminate the need for more than 10 external discrete components and reduce overall system cost in consumer electronics, such as mobile handsets, digital cameras and portable navigation devices.

TXS0206 features include clock frequencies up to 52 MHz; data rates up to 60 Mbps; support for 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V power-supply voltages; built-in IEC 61000-4-2 ESD protection; data line EMI filter circuitry; and integrated SD-compliant pull-up resistors.

Pricing: 1000-unit quantities is $0.99.
Availability: Now in a 20-bump WCSP package. Additional family members, including integrated 1.8-V or 2.9-V CMOS LDO voltage regulators to power SD/MMC memory cards, will be available in 1H 2009.
