TCA5013: How to use the CLKINx and IOCx pins?

Andrew Su

Part Number: TCA5013

Dears,

we are pushing TCA5013 for smart phone, the customer has some issues as below:

1. how to connect the D9(CLKIN1),F9(CLKIN2),E8(IOUC_1),F8(IOUC_2) with the controller? is it I2C Bus alike?

2. how to connect D9(CLKIN1),E8(IOUC_1) pins if the user card is not employed? pull them to GND or just let them floating?

3. what type of user card does TCA5013 support? only SMART CARD?

4. has TCA5013 been employed with MTK mobile phone platform? what Android version may TCA5013 support?

5. If the ISO7816 protocol been built-in the driver code?

thanks!

1: IOMC1/IOMC2 connect to GPIO pin, CLKIN1/CLKIN2 connect to CLK pin

2: if not used , just pull them GND.

3: support smart card compliant with EMV4.3, ISO7816-3 and ISO7816-10

4: so far not employed with MTK mobile phone platform.

5: no

dear Brain,

thanks a lot for the information.

we are still confused that what kind of Bus should we connect the pins D9(CLKIN1) & E8(IOUC_1),F9(CLKIN2) & F8(IOUC_2), should we use I2S,UART,I2C or SPI to read the data? or what kind of timing/protocol should we follow to communication via D9(CLKIN1) & E8(IOUC_1),F9(CLKIN2) & F8(IOUC_2)?

thanks!

it's LVCMOS signal, like I2C
