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.
