Cost-Effective Smart Card Interface device. board (FR4 material) is implemented in two metal layers. Figure 1. Demo Board Description Main Features Example of Equipment (Note 1) Qty.
- Equipment used in the context of this Application Note Manual.
- Greater Scope memory per channel offers better resolution.
starting measurements on the board.
- Set the CMDVCC/ in the OFF position (High).
- Set CLKDIV1 and CLKDIV2 into low position (lowest frequency Fclkin)
- 2 pins are used to change the Card VCC power supply or the smart card interface mode which can be 1.8 V , 3.0 V or 5.0 V . These 2 pins are VSL0 and VSEL1 and on the board, changing VSEL0 and VSEL1 is done using 2 corresponding switches (see Figure 2) according to the below Table 1. When VSEL0 = 0 then VSEL1 is in the mode 5 V/3 Vbar, when VSEL0=1 then VSEL1 is in the mode 1.8 V / 3 Vbar . The initial setup can be VSEL0 = 0 and VSEL1 = 1 for selecting the 5 V mode. The card VCC (CVCC) output voltage cannot be changed on the fly when the smart card interface is active (/CMDVCC = Low). For changing card VCC it is necessary to deactivate the device then to reconfigure the card VCC by setting the appropriate VSEL0 and VSEL1 finally the smart can be activated again with this new smart card power supply voltage.
Table 1. CVCC Programming
- As a precaution, turn the 1 k/C0087 potentiometer to obtain a resistor output value of 1 k/C0087, and then connect the jumper. DC Power Supplies Two power supplies are used to bias the demo board. VDDP is the input voltage of LDO Regulator. V DD is the “digital” power supply which biases the input stages of the NCN8025A device (control and signal inputs). VDD and VDDP must be connected to the board to ensure correct operation. Connect the V DD and V DDP power supplies using the 2 pin male connectors J2 and J1 respectively. Clock Frequency CLKDIV1 and CLKDIV2 select the frequency divider according to the table given below.
Table 2. Clock Division Ratio Programming The clock is applied externally (SMB connector).
- Set CLKDIV1 and CLKDIV2 to select the correct frequency.
- Set 5 V / 3 Vbar to select the correct output voltage.
- Jumpers: − 1 k/C0087 potentiometer jumper: not connected to start the measure.
- Finally, toggle /CMDVCC from High to Low to start the device (activation sequence run).
