Consumer electronics designers save cost and board space with the industry's smallest, most highly integrated SD/MMC voltage level translator

Eliminates the need for more than 10 external discrete components

Jan 15, 2009

DALLAS (Jan. 15, 2008) - 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, introduced today by Texas Instruments (TI) (NYSE: TXN). 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

  • 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
  • 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 1H 2009.
