ZCU102 Evaluation Board User Guide www.xilinx.com 53UG1182 (v1.2) March 20, 2017Chapter 3: Board Component DescriptionsCP2108 Channel 3 MSP430 UART InterfaceThe CP2108 Channel 3 MSP430 UART interface circuit is shown in Figure 3-16. Theconnections from MSP430 U41 to CP2108 U40 via TSX0104E level shifter U53 are listed inTable 3-17.GPIO (MIO 13, 38)These two (2) GPIO bits are connected to the U41 MSP430 system controller for generalpurpose signaling or communications between the Zynq UltraScale+ MPSoC device and theMSP430 system controller. These signals are level-shifted by TSX0108E U141. Theconnections between the U41 system controller and the XCZU9EG MPSoC are listed inTable 3-18.X-Ref Target - Figure 3-16Figure 3-16: MSP430 USB UART InterfaceTable 3-17: MSP430 U41 to CP2108 U40 Connections via L/S U53MSP430 U41 Schematic Net Name CP2108 U40Pin Name Pin No. Pin Name Pin No.P3_3 26 UART3_TXD_O_MSP430_UCA0_RXD TX_3 4P3_3 25 UART3_RXD_I_MSP430_UCA0_TXD RX_3 1Table 3-18: System Controller U41 GPIO Connections to XCZU9EG U1XCZU9EG(U1) Pin Net Name MSP430 U41Pin Name Pin No.AK17 MIO13_PS_GPIO2 20 P1_7L23 MIO38_PS_GPIO1 19 P1_6Send Feedback
