ST6G3244ME

Level translator for SD, SDIO, mini SD, and micro SD Cards

with internal I/O supply and ±15 kV ESD protection

Features

■ Supports 60 MHz clock rate

■ Supports DDR mode for SD Card™

■ Compliant with

– SD Specification Part 1 Physical Layer

Specification 3.00 (SDR12, SDR25,

DDR50)

– SD Specification Part 1 Physical Layer

Specification 2.00

■ Bi-directional with direction control pin

■ Balanced propagation delays: tPLH ≈ tPHL

■ LDO power-down support. When the LDO is

powered down, VCCB is pulled to GND via

the 130

Ω resistor. When VCCB = 0 V, there is

no additional leakage seen on VCCA.

■ EMI filtering and signal conditioning

■ Supports both 1.8 V and 2.9 V data translation

on card side

■ Integrated LDO to supply 1.8 V or 2.9 V power

for B-side I/Os (pin-selectable); can be used

also externally

■ Integrated pull-up and pull-down resistors on

B-side

■ Operating voltage range

–VCCA = 1.62 V to 1.98 V

–VBAT = 3.0 V to 5.0 V

■ Latch-up performance exceeds 100 mA

(JEDEC Standard 78)

■ ESD protection for card side (B-port, CD and

WP pins)

– ±8 kV contact discharge (IEC61000-4-2)

– ±15 kV air-gap discharge (IEC61000-4-2)

■ ESD protection for host side (A-side)

– ±2 kV HBM (JEDEC 22-A114)

– ±200 V MM (JEDEC 22-A115)

■ Operating temperature range –40 °C to +85 °C

■ Space-saving Flip Chip 25 package

(2 x 2 x 0.605 mm, 0.4 mm bump pitch)

■ RoHS compliant, lead-free soldering capable

Applications

■ Mobile phones, smartphones

■ PDAs

■ Cameras

■ SD Card readers

■ Any device with SD memory card
