NCN8026AMNGEVB NCN8026A Evaluation Board User's Manual http://onsemi.com EVAL BOARD USER’S MANUAL INTRODUCTION This document gives a detailed description of the NCN8026A Evaluation Board (QFN-24) with the bill of materials (BOM), board schematic, and layout. The appropriate laboratory test setups are also provided. The NCN8026A Evaluation Board has been designed to help for a quick evaluation of the NCN8026A Smart Card Interface device. This document has to be used with the NCN8026A datasheet. The datasheet contains full technical details regarding the NCN8026A specifications and operation. The board (FR4 material) is implemented in two metal layers. The top and bottom layers have thicknesses of 35 mm. The PCB thickness is 1.6 mm with dimensions of 89 mm by 68 mm (see Figure 1). Figure 1. Evaluation Board TEST EQUIPMENT The following equipment listed in Table 1 is suggested for the evaluation. Table 1.

Refer to the recommended operating ranges for VDD and VDDP in the datasheet. Use VDD = VDDP = 5 V to get started. Refer to Figure 2 for an overview of the main features of the evaluation board. Initial Setup The initial setup given here is recommended before starting measurements on the board. • Set the CMDVCC/ in the OFF position (High). • Set CS/ in the ON position: Chip selected, position Low. • Set CLKDIV1 and CLKDIV2 into low position (lowest frequency FCLKIN ) • VESL0 and VSEL1 are used to change the output CVCC (card power supply) or the smart card interface mode which can be 1.8 V, 3.0 V or 5.0 V. Change VSEL0 and VSEL1 using the switches (see Figure 2) according to Table 2 below. 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 CVCC output voltage can be changed on the fly when the smart card interface is active (/CMDVCC = Low). Nevertheless, it is recommended to change CVCC after having deactivated the device then reconfiguring CVCC by setting the appropriate VSEL0 and VSEL1 and reactivating the smart card interface. Clock Frequency CLKDIV1 and CLKDIV2 select the frequency divider for the card clock CCLK according to Table 3 given below. Table 3. CVCC PROGRAMMING CLKDIV1 CLKDIV2 CCLK Frequency 1 0 fCLKIN / 1 1 1 fCLKIN / 2 0 1 fCLKIN / 4 0 0 fCLKIN / 8 The Clock The clock is applied externally (SMB connector). Refer to the datasheet for the recommended frequency and voltage levels that can be applied at CLKIN. Card Presence The typical socket is normally open, so PRES/ has been chosen; nevertheless the PRES and PRES/ test points can also be used for signaling the presence of a card and starting up the circuit. If not using a smart card, connect PRES/ to ground. Table 2. CVCC PROGRAMMING Start the measurement VSEL0 VSEL1 CVCC 0 0 3.0 V 0 1 5.0 V 1 0 3.0 V 1 1 1.8 V To start the measurments, set the board as it follows: 1. Set CLKDIV1 and CLKDIV2 to select the correct frequency. 2. Set VSEL0 and VSEL1 to select the correct output voltage. 3. Check that the 1 kW potentiometer jumper is turned to 1 kW. 4. Set /CS low. 5. Set CMDVCC/ high. 6. Check that VDD and VDDP are set to 5 V, and set the current limit to 100 mA. Turn on the power supplies VDD and VDDP. 7. Toggle /CMDVCC from High to Low to start the device (activation sequence run). 8. Change the CVCC output voltage with the VSEL0 and VSEL1 switches. 9. Apply a clock to CLKIN and observe the card clock at CCLK. Use CLKDIV1 and CLKDIV2 to change the clock frequency. • As a precaution, if using the built-in resistive load, turn the 1 kW potentiometer to obtain a resistor output value of 1 kW, 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. VDD is the “digital” power supply which biases the input stages of the NCN8026A device (control and signal inputs). VDD and VDDP must be connected to the board to ensure correct operation. Connect the VDD and VDDP power supplies using the 2 pin male connectors J4 and J3 http://onsemi.com 2 NCN8026AMNGEVB EVALUATION BOARD DESCRIPTION Figure 2.
