This document presents the steps to setup an environment for using the EVAL-CN0235-SDPZ evaluation board together with the Xilinx KC705 FPGA board and the Xilinx Embedded Development Kit (EDK). Below is presented a picture of the EVAL-CN0235-SDPZ Evaluation Board with the Xilinx KC705 board.

Below is presented a picture of SDP-B Controller Board with the EVAL-CN0235-SDPZ Evaluation Board.

The CN0235 board is a fully isolated lithium ion battery monitoring and protection system. Lithium ion (Li-Ion) battery stacks contain a large number of individual cells that must be monitored correctly in order to enhance the battery efficiency, prolong the battery life, and ensure safety.

The AD7280A contains all the functions required for general-purpose monitoring of stacked lithium ion batteries as used in hybrid electric vehicles, battery backup applications, and power tools. The part has multiplexed cell voltage and auxiliary ADC measurement channels for up to six cells of battery management. An internal ±3 ppm/°C reference is provided that allows a cell voltage accuracy of ±1.6 mV. The ADC resolution is 12 bits and allows conversion of up to 48 cells within 7 us.

The AD8280 is a hardware-only safety monitor for lithium ion battery stacks. The part has inputs to monitor six battery cells and two temperature sensors (either NTC or PTC thermistors). The part is designed to be daisy-chained with other AD8280 devices to monitor a stack of significantly more than six cells without the need for numerous isolators. Its output can be configured for an independent or shared alarm state.

The first objective is to ensure that you have all of the items needed and to install the software tools so that you are ready to create and run the evaluation project.

• Xilinx KC705 FPGA board
• FMC-SDP adapter board
• EVAL-CN0235-SDPZ evaluation board

• Xilinx ISE 14.6.
• UART Terminal (Termite/Tera Term/Hyperterminal), baud rate 115200.
• The EVAL-CN0235 reference project for Xilinx KC705 FPGA.

• Use the FMC-SDP interposer to connect the ADI evaluation board to the Xilinx KC705 board on the FMC LPC connector.
• Connect the JTAG and UART cables to the KC705 and power up the FPGA board.

The following commands were implemented in this version of EVAL-CN0235 reference project for Xilinx KC705 FPGA board.

Commands can be executed using a serial terminal connected to the UART peripheral of Xilinx KC705 FPGA.

The following image shows a generic list of commands in a serial terminal connected to Xilinx KC705 FPGA's UART peripheral.
