General Description
The MIC4555 is a digital level shifter with a 50mA LDO for
SIM card interfaces. There are three high-speed level
shifters for SIM card signal translation. The level shifters
are designed to support high-speed clocking up to 5MHz.
The 50mA LDO provides power for the SIM Card to
eliminate the need for a separate power device. This
simplifies the design of the SIM card interface. The
MIC4555 is available in a tiny, lead-free, 16-pin MLF
package (3mm x 3mm), and is specified to operate from
40°C to +125°C junction temperature.
Data sheets and support documentation can be found on
Micrel’s web site at: www.micrel.com.

Input voltage 2.7V to 5.5V
Controller voltage 1.6V to 5.5V
Supports clock rates greater than 5MHz
8kV ESD protection on SIM contact pins
16-pin 3mm x 3mm MLF package
40°C to +125°C junction temperature range
Applications
SIM card interface for 3G/4G systems
Wireless PC cards
Smart card readers
