EMIF06-mSD02C3

Mini and micro-SD card IPAD™ EMI filtering and ESD protection

Features

■EMI low-pass filter

■ESD protection ±15 kV (IEC 61000-4-2)

■Integrated pull up resistors to prevent bus floating when no card is connected

■50 MHz clock frequency compatibility with Cline < 20 pF

■Low power consumption

■Easy layout thanks to smart pin-out configuration

■Very low PCB space consuming

■High reliability offered by monolithic integration

■Reduction of parasitic elements thanks to CSP integration

■Lead-free package

Complies with the following standards:

■IEC 61000-4-2 level 4

–15 kV (air discharge)

–8 kV (contact discharge)

■MIL STD 883G - Method 3015-7 Class 3A

■SD Specification Part 1, Physical Layer Specification, Version 2.0

Application

Mini and micro (T-Flash) secure digital memory card in:

■Mobile phones

■Communication systems

Flip Chip (16 bumps)
