Not long ago STRATIX 10 SX FPGA programmable chip is started soon, this is the only FPGA, which is the only integrated four-core ARM CORTEX-A53 CPU processor, and INTEL acquires Altera, further verifying the integrated processor on a single chip. And FPGA programmable ability, the feasibility of this technology, the prospect, high performance processing capability, with flexible programmable configuration, becoming an important direction in the development of FPGA technology. And the current representation of this direction, representative products, is also the Zynq-7000 programmable SOC series products launched by Xilinx. As of now, there are many mature equipped with Xilinx Zynq- 7000 programmable SOC's FPGA development board, such as today's love board network to give you a Z-Turn Lite development board.
Z-Turn Lite Development Board is the most recently introduced FPGA + ARM of Mil Technology, based on the latest XC7Z007S single-core ARM + FPGA's SOC (core optional XC7Z010) in the Xinci Zynq-7000S series. On the development board version and peripherals, Z-Turn Lite is the same as Mir Technology's Z-Turn Board in 2015, equipped with the necessary 10/100 / 1000m network port, USB OTG, TF card, JTAG interface, The remaining interfaces are taken out by extended pin, but the entire board is only 460RMB, which makes it easy for users to achieve chip assessment and product development at minimum cost.
Z-Turn Lite out of the box
The Z-Turn Lite development board got from the panel is a kit, which is not a single board, so that the box is still internally accessories.
The accessories of internal development board are very complete, with HDMI lines, USB cables, network cables, etc., no engineers need to purchase additional. In addition, the self-contained disc data is a large aspect of the engineer's quick start, no need to find information on the Internet, of course, for a lot of computers that have already given up the CD-ROM, this disc is also very embarrassing.

Z-TURN Lite Hardware Parameters
Look at this Z-Turn Lite development board, like the Z-TURN development board launched by Mil Technology, size is 91mm * 63mm, only better than our ID card, black PCB, 10 floor design, Shenjin process , The board is exquisite, it looks high.

XILINX ZYNQ-7000 SOC
The Z-Turn Lite development board uses Xilinx Zynq-7000 All ProgramMable SoC. ZynQ-7000 Series SOC is divided into a PS (Protive System) section, where the PS part is a bit like a traditional processor internal structure, including CPU core, graphic acceleration, floating point operation, storage controller, various Communication interface peripherals and GPIO peripherals, and the PL part is traditional programmable logic and supporting multiple standard IO, which are interconnected between internal high-speed bus.
This architecture improves system performance (hardcore "of processors and various peripherals), and simplifies the system's construction (programmable peripheral configuration) while providing sufficient flexibility (programmable logic) ), On the Z-Turn Lite development board, the PS portion mainly refers to the Cortex-A9 ARM processor, connects specific storage and interface, and the PL portion is primarily connected to the FMC and the Debug interface.
It is worth noting that the Z-Turn Lite development board SOC model supports XC7Z007S / 14S / XC7Z010 / 20, package CLG400 (17 x 17 mm), pin-to-pin compatible.
The four SOC PS parts mainly distinguish XC7Z007S / 14S as single core A9, the frequency up to 766MHz, XC7Z010 / 20 is dual core A9, the frequency up to 866MHz;
The PL part is mainly different from logical resources, and XC7Z007S / 10 / 14S / 20 is in turn, and the specific situation is referred to in the table below.
Z-Turn Lite Development Board Peripheral
The other interface details of the Z-Turn Lite development board are shown below:
The USB OTG function is implemented by external USB3320 PHY, and Gigabit Ethernet port functions are implemented by KSZ9031RN PHY.
The picture below shows the configuration interface of the PL Bank power supply, which can be configured as 1.8V 2.5V 3.3V power supply, which defaults to 3.3V.
As shown in the figure below, from left to right interfaces, the JTAG interface, Boot selects the jet interface, and debug the serial interface.
The only regret is that there is no onboard programmer, and friends who need to develop have to purchase additional.
Z-TURN Lite Development Board
There must be a few more attention before formally use the Z-Turn Lite development board. We can also see from board cards that the needle-pin extension interface is rich, board configuration is a huge "challenge", which we especially pay attention to the configuration of the board boot boot item.
Z-TURN Lite Development Board has four different start-up mode, and the JTAG debugging function, QSPI flash start, NAND FLASH, and SD card launch settings, and the palette of Mir Technology is equipped with SD card itself. Moreover, the setting of the jumping is also in the SD card launch mode, so the factory default power-on start is the SD card start mode.
In addition, the development board manual claims that the power consumption of Z-TURN LITE is about 8W, and the 5V / 2A adapter provided by the fitting is sufficient to cope. The picture below is the power block diagram of the Z-Turn Lite development board. The power-on process is completed in the order of 1.0V->1.882.3.3.3.5V->3.3V / 2.5V, 3.3V last Enable, then reset the system.
Set the serial number monitoring to the development board.
In the system launched, it was found that the displayed 1GB DRAM, the board is the two memory granules of Magoguang, specially go to the US Optical official website, two are 256MB, together is 512MB DRAM, it seems a bit problem.
In addition, it was found that the detection CPU was two-core, undoubtedly determined that the system is estimated in the MicroSD card is the custom system of Mil Technology's previous Z-TURN development board, and the official staff will not re-revive. Give it. Careless? Fortunately, this is only a development board, and the system update iteration is normal and does not affect the use.
The built-in system has been compiled with relevant driver followers, so many external settings can be driven directly through commands, such as LEDs on the Z-Turn Lite development board.
In addition, the user manual, schematic, source and mirroring of the chip of the Z-Turn Lite development board are included in the Z-Turn Lite development board. Some files, and some files for some tool software and Vivado are included in the DVD CD. Z-Turn Lite needs to use Xilinx design suite Vivado Design Suite, Vivado is a new generation of highly integrated development kits that Xilinx launched a new generation of highly integrated product lines for SOC full range of products, including logic design, IP Integration, embedded system, simulation, DSP design, etc., software installation and use can refer to the Z-Turn Lite entry instruction manual provided by Mil Technology, this article will not explain one by one.
summary
Introduced Mil Technology's latest FPGA + ARM embedded development board Z-Turn Lite, board is equipped with the latest Zynq-7000 series single-core SOC, the price is extremely high, support Linux system, board use and Z -Turn Similar card structure, on-board extension interface, such as serial port, network port, USB OTG, etc., the only place where users may need to purchase additional programmers; in addition to this, Mil Technology provides developers The rich information of the Z-Turn Lite development board, such as the user manual, PDF floor schematic, external expansion interface driver, BSP source package, development tool, perfect software development environment, but not only reduces the difficulty of users development, but also Reduce product development cycles and achieve rapid listing of products. In summary, Z-Turn Lite only sold only 460RMB prices can undoubtedly win the title of the Xilinx Zynq-7000 Series FPGA development board, interested friends can consider starting.
