Application note
5.3.1 MMC interfacing using IP4060CX16/LF
5.4 Memory Card interface using IP4052CX20/LF
The IP4060CX16/LF contains ESD protection, EMI filtering and provides pull-up resistors
according to the MMC specification for a 4-bit interface implementation. Even though the
CMD line pull-up resistor value is lower than the 10 kΩ recommended in the SD-memory
card specification, the IP4060CX16/LF is often used in conjunction with this interface.
A typical application is depicted in the following schematic:
Another product suitable for the memory card interface is the IP4052CX20/LF. This ESD
protection and EMI filter device contains 6 channels for CMD, CLK and 4 data channels
plus 2 spare resistors in order to e.g. bias a card detection switch.
Compared to other devices, the IP4052CX20/LF contains pull-up resistors for the 4 data
channels and the CMD channel. In addition, it also contains a relatively low-ohmic pull-up
resistor connected to the CMD channel.
The maximum filter channel capacitance is 20 pF which makes the device suitable for
high clock-speed applications as well.
Electrical card detection for the SD-memory card is not supported.
The most important electrical parameters are listed in
