Product profile

1.1 General description

The IP4365CX11 is a fully integrated smart card interface device according

ISO/IEC 7816-3 for the Subscriber Identity Module (SIM) card interface and according

ISO/IEC 7816-12 for the Universal Subscriber Identity Module (USIM) Universal Serial

Bus (USB) interface. It is designed to provide ElectroMagnetic Interference (EMI) filtering

and ElectroStatic Discharge (ESD) protection for the conventional digital interface and

also for the USB interface.

The 3-channel EMI filter is identical to the filter available as ESD protection and EMI filter

IP4366CX8 (which does not contain the additional USB full speed ESD protection). It also

provides RC low-pass filtering of undesired Radio Frequency (RF) signals in the 800 MHz

to 3000 MHz frequency band. The IP4365CX11 is designed to provide protection to

downstream components from ESD voltages as high as

±15 kV contact discharge and

>

±15 kV air discharge according the IEC 61000-4-2 model, far exceeding standard

level 4.

The device is fabricated using monolithic silicon technology and integrate three resistors

and several high-level ESD-protection diodes in a single Wafer-Level Chip-Scale Package

(WLCSP). These features make the IP4365CX11 ideal for use in applications requiring

the utmost in miniaturization such as mobile phone handsets, cordless telephones and

personal digital devices.
