10Application Examples
10.1 Example VNC2 Schematic (MCU – UART Interface)
VNC2 can be configured to communicate with a microcontroller using a UART interface. An example of
this is shown in Figure 10.1.
Figure 10.1 VNC2 Schematic (MCU – UART Interface)
NOTES: This sample circuit is not intended to be a complete design. It shows the minimum connections
for a basic VNC2 circuit. The value of the capacitors connected to the crystal will depend on the
requirements of the crystal. The 5V0_SW power signal assumes proper switching and over-current
detection conform to the USB-IF specifications for a USB host port. The 120uF capacitor should be a low-
ESR type. The value of the ferrite beads may need adjusted for EMI compatibility. Input and output
capacitors for the 3.3V regulator should be chosen according to the datasheet of the selected part. The
VNC2 outputs connect to the MCU intputs and MCU outputs to VNC2 inputs (TXD to RXD and RTS# to
CTS# in each direction).
NOTE for VNC2-48L1B ONLY: With the 48-pin LQFP package, pin 7 is not connected (VREGOUT). The
regulator output has an internal connection to VCCPLLIN to accommodate a migration path from VNC1L
designs. In this case, pin 3 (VCCPLLIN) requires only one 100nF capacitor to ground. All other packages
require the external circuitry shown to connect VREGOUT to VCCPLLIN.
