DDR3 DRAM

• The FPGA core board AC7Z010 is equipped with two Micron DDR3 SDRAM chips (1GB in total), model MT41K128M16TW-107 (Compatible with Hynix
• H5TQ2G63AFR-PBI). The total bus width of DDR3 SDRAM is 32bit. DDR3 SDRAM operates at a maximum speed of 533MHz (data rate1066Mbps). The DDR3 memory system is directly connected to the memory interface of the BANK 502 of the ZYNQ Processing System (PS). The specific configuration of DDR3 SDRAM is shown in Table 2-3-1 below:

Table 2-3-1: DDR3 SDRAM Configuration

The hardware design of DDR3 requires strict consideration of signal integrity. We have fully considered the matching resistor/terminal resistance, trace impedance control, and trace length control in circuit design and PCB design to ensure high-speed and stable operation of DDR3.

DDR3 DRAM pin assignment:

QSPI Flash

The FPGA core board AC7Z010 is equipped with one 256MBit Quad-SPI FLASH chip, the flash model is W25Q256FVEI, which uses the 3.3V CMOS voltage standard. Due to the non-volatile nature of QSPI FLASH, it can be used as a boot device for the system to store the boot image of the system. These images mainly include FPGA bit files, ARM application code, and other user data files. The specific models and related parameters of QSPI FLASH are shown in Table 2-4-1.

Table 2-4-1: QSPI FLASH Specification
QSPI FLASH is connected to the GPIO port of the BANK500 in the PS section of the ZYNQ chip. In the system design, the GPIO port functions of these PS ports need to be configured as the QSPI FLASH interface. Figure 2-4-1 shows the QSPI Flash in the schematic.

Clock configuration

The AC7Z010 core board provides an active clock for the PS system, so that the PS system can work independently.
PS system clock source
The ZYNQ chip provides 33.333333MHz clock input for the PS part through the X1 crystal on the core board. The clock input is connected to the PS_CLK_500 pin of the ZYNQ chip BANK500. Its schematic diagram is shown in Figure 2-5-1:

Power Supply
The power supply voltage of the AC7Z010 core board is DC5V, which is supplied by connecting the carrier board. In addition, the power of BANK34 and BANK35 is also provided through the carrier board. The schematic diagram of the power supply design on the core board is shown in Figure 2-6-1:

The FPGA development board is powered by + 5V, and is converted into + 1.0V, + 1.8V, + 1.5V, + 3.3V four power supplies through four DC / DC power chips. The output current of + 1.0V can reach 6A, + 1.8V and + 1.5V power output current is 3A, + 3.3V output current is 500mA. J29 also has 4 pins each to supply power to FPGA BANK34 and BANK35. The default is 3.3V. Users can change the power of BANK34 and BANK35 by changing VCCIO34 and VCCIO35 on the backplane. 1.5V generates the VTT and VREF voltages required by DDR3 through TI’s TPS51206. The functions of each power distribution are shown in the following table:

BANK501 IO voltage

+3.3V| ZYNQ Bank0,Bank500,QSIP FLASH

Clock Crystal

Because the power supply of the ZYNQ FPGA has the power-on sequence requirements, in the circuit design, we have designed according to the power requirements of the chip. The power-on sequence is+1.0V->+1.8V->(+1.5 V, +3.3V, VCCIO) circuit design to ensure the normal operation of the chip. Because the level standards of BANK34 and BANK35 are determined by the power supply provided by the carrier board, the highest is 3.3V. When you design the carrier board to provide the VCCIO34 and VCCIO35 power for the core board, the power-on sequence is slower than + 5V.

Board to Board Connectors pin assignment
The core board has a total of two high-speed expansion ports. It uses two 120-pin inter-board connectors (J29/J30) to connect to the carrier board. The PIN spacing of the board to board connector is 0.5mm, among them, J29 is connected to 5V power, VCCIO power input, some IO signals and JTAG signals, and J30 is connected to the remaining IO signals and MIO. The IO level of BANK34 and BANK35 can be changed by adjusting the VCCIO input on the connector, the highest level does not exceed 3.3V. The AX7Z010 carrier board we designed is 3.3V by default. Note that the IO of BANK13 is not
