Texas Instruments Incorporated (Texas Instruments) has introduced a new tiny, highly integrated Secure Digital (SD)/MultiMedia Card (MMC) voltage level translator, TXS0206. The new TXS0206 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.
By using this TXS0206 translator engineers can now bridge the gap between two disparate voltage nodes while maintaining digital switching compatibility. 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.
TXS0206 features:
Clock frequencies up to 52 MHz,
Data rates up to 60 Mbps,
Supports 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 and availability:
The TXS0206 is available now in a 20-bump WCSP package. Suggested resale pricing in 1000-unit quantities is $0.99. 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 first half of 2009.
