Functional Description
The following sections provide brief descriptions of each feature provided on the MiniZed board.
Zynq 7Z007S SoC
The Zynq 007S device (in the CLG-225 package) contains:
Processor System (PS):
Single-core ARM® Cortex™-A9
Max frequency 667MHz
256 KB on-chip RAM
84 PS I/O pins
USB 2.0 OTG, SDIO x 2, UART x 2, SPI x 2, I2C x 2 etc.
Logic Elements (LE):
Programmable logic architecture equivalent to an Artix -7 FPGA
23K Logic Cells
1.8Mb Block RAM (50 x 36Kb blocks)
54 High Range (1.2V to 3.3V) I/O pins
The 225-pin package is used since this is the lowest cost device in this family
This package restricts the DDR interface to 16 bits
Only one USB master interface is supported
Only 1 of the 2 SDIO controllers in the PS are available directly from the PS, the other
through EMIO. The CLG225 does not support booting from SD Card.
One PS UART is routed to the computer via USB, the other is used for communication with
the Bluetooth part of the Murata wireless module. For communication with Shield or Pmod
peripherals, one of these UARTs can be re-purposed or another UART can be instantiated
in the PL.
I/O levels of 3.3V are supported for PMOD and Arduino peripherals.
All MIO pins are 3.3V.

Page 14
SoC IC Package
The CLG225 package is a 225-pin 13mm x 13mm BGA with a 0.8mm ball pitch. The image below
indicates the locations of the various I/O pins as seen from the top.
Figure 2 – I/O Bank Pin Locations (Top view)
Device configuration
Device configuration, i.e. the programming of both the PS and the PL, can be achieved in a number
of ways:
Using JTAG via the on-board USB-to-JTAG circuitry to configure the SoC using the Xilinx
SDK, which is based on Eclipse (see [8])
Loading an image from the QSPI flash device
Loading the First Stage Boot Loader (FSBL), Second Stage Boot Loader (SSBL) and PL
bitstream from QSPI flash so that the Petalinux components can be loaded from either the
on-board eMMC or from an external mass storage device such as a Micro SD (uSD) card
plugged into a Pmod socket using SDIO

Page 15
Debug interface
Historically the use of a JTAG debugger involved a JTAG connector and the use of an additional
JTAG pod/cable. The MiniZed board has on-board JTAG circuitry that allows JTAG programming
and debug using a standard USB cable.
The USB-to-JTAG interface uses a 2-port USB-to serial converter from FTDI, the FT2232.
To use the FT2232 device, the computer must have the FTDI driver installed, as well as
Vivado 2017.1 or later. (see [7])
The first FT2232 port is used for USB-to-JTAG, while the second is used for USB-to-UART.
The USB-to-UART enumerates as a COM port on the computer when the EEPROM is
correctly programmed.
If looking to add an on-board USB-to-JTAG configuration solution to a custom board, please
see AR# 68889 provided by Xilinx for available solutions.
https://www.xilinx.com/support/answers/68889.html
I/O Levels
The MiniZed’s Zynq SoC allows programmable voltage levels for PS I/O pins (1.8V or 3.3V) and for
PL I/O pins (1.2V to 3.3V).
PS I/O pin assignments are typically the result of trade-offs between functions, as they are
multiplexed onto the same bonded out I/O pins, known as MIO pins.
The MIO pins are divided into two banks, i.e. Bank 0 = MIO0-15 and Bank 1 = MIO16-53.
In Vivado the I/O voltage levels for both these banks are set to 3.3V (and not 1.8V).
Peripherals such as SDIO, UART, I2C and SPI can be selected to interface directly to the
PL, in which case they are mapped to EMIO (Extended MIO) pins. These pins can be used
in the PL and/or can be routed to PL I/O pins
All the MiniZed’s PL I/O pins are HR (high range, i.e. 1.2V to 3.3V). All PL banks are set to
the 3.3V range.
The 54 PL pins are defined to be 27 differential signal pairs. When the bank I/O supply is
3.3V, as for most MiniZed PL banks, LVDS is supported as input only.

Power Banks
There are various I/O banks that can be powered separately. The table below shows how those
I/O banks are powered on the MiniZed board.

Storage
The Zynq PS has 256 KBytes of on-chip RAM. The MiniZed supports 3 types of external memory:
512 MBytes of DDR3L, which is RAM for data and program storage
128 Mbits of QSPI NOR Flash
8 Gbytes of eMMC or SD Card via external PMOD (not included in kit)
Micron DDR3L memory
The MiniZed has a 4Gb (512 MB) DDR3L Micron MT41K256M16TW-107 memory device
The CLG225 package Zynq deice only supports a 16-bit wide memory interface (not x32).
This is a 1.35V device in a 96-ball 8mm x 14mm package
DDR termination voltage and reference are provided by the Dialog DA9062 PMIC
DDR termination voltage of 0.675 V is provided
Micron QSPI flash memory
The QSPI interface is a 3.3V NOR Micron MT25QL128ABA8E12-0SIT flash device.
The MiniZed’s 128Mbit QSPI device can be expected to be large enough to run almost any bare
metal application. It is also possible to run Petalinux from the QSPI dependent on how large of a
build it is. However in most Petalinux builds the QSPI will be used to store the First Stage Boot
Loader.
Micron on-board eMMC memory
Embedded Multi-Media Controller/Card (eMMC) is a mechanism to allow the ARM controller access
to large banks of NAND flash without the requirement to actively manage the NAND.
The MiniZed board has an 8GB eMMC Micron MTFC8GAKAJCN-4M IT device.
- MiniZed is designed to operate the eMMC SDIO interface in high-speed mode, up to
50 MHz.
- The 3.3V device allows for a 4-bit interface, which means that 4 of the 8 data lines can
be used for a 6-wire SDIO interface to the Zynq device.
- Block management is implemented on the device. The device also includes a built-in
error correction code (ECC) algorithm to ensure that data integrity is maintained.
- Zynq cannot boot directly from eMMC. The FSBL has to be in the QSPI flash device
to boot from eMMC.

Page 18
External SD card
Note that the 7Z007S in the CLG225 package cannot use an SD card for primary boot since that
requires that the SD Card reside on the SDIO peripheral on MIO pins 40-45, and these pins are not
available in the CLG225 package. This means that primary boot must be from QSPI flash or from
JTAG.
A (micro) SD card can be used if it is accessed via a Pmod slot.
This will require the SDIO interface to be moved programmatically from hard-wired MIO
pins to EMIO pins. Two GPIO pins for CD and WP will also have to be used. This is
illustrated in the diagram below.
Using EMIO will reduce the SDIO bus max clock speed from 50MHz (MIO) to 25MHz
(EMIO).

Power Supply
Power requirements
The MiniZed requires support for the input and output voltages and currents shown in Table 3.
Table 3 – Board power requirements
Bank
Voltage
Current (A)
Vccint / Vccpint 1 V 1.5
Vccaux / Vccpaux 1.8V 0.5
Vcco (DDR) 1.35V 1
Vcco 3.3 3.3V 1
DDR VTT 0.68V 0.5
DDR VREF 0.68V 0.1
Vin 5V 2.4
All supplies require 5% tolerance. These current values reflect the worst case power consumption
of both the Zynq device (taken from Xilinx Power Estimator tool) as well as the other on-board
circuitry.
Optional external power supply - AES-ACC-MINIZ-PWR
A single USB 2.0 port is only required to provide 500mA. The power budget for the board shows
that this power level is easily exceeded when the Zynq device operates under heavy utilization.
A secondary micro USB power input is provided with a micro-USB cable.
When the MiniZed user wants to use more current, he/she will have to provide power from a
secondary micro USB input.
In the case of having a large input source, user can populate R114 which will link the two
power inputs thus requiring only the single input source.
A “power kit” that consists of a 5V supply and a USB cable can be sold as an add-on item
when ordering a MiniZed board.
The two micro USB inputs are connected directly, with each supply being protected by a
blocking diode as in the image below.

Figure 5 – Power Source Selection and Diode
Also shown above is the powering of an Arduino-compatible shield.
A shield can be powered from the MiniZed through 5V and 3.3V. Both supply
voltages have a small diode drop that is proportional to the current drawn. If the
shield draws 500 mA, there could be a 0.3V drop.
A blocking diode protects the MiniZed supply output in the case of the shield being
powered independently.
In the case of it being powered independently, the shield 5V supply is not protected.
The user can remove the resistor in the 5V path to disconnect the 5V source if this
should be a problem.
The Arduino VIN pin can be used to power a board from the shield. This use case
is not supported, but the signal will be taken to a hole in the PCB.
Power-pack add-on kit
This MONOPRICE AVTCB-10273 external input supply is rated for 2.4A at 5V, allowing sufficient
power to feed:
The MiniZed Board with the PS and PL both running at Maximum frequency and utilization
All on-board peripherals, such as the Wi-Fi and Bluetooth active
All slave devices such as a USB slave, Arduino shield and Pmod peripherals active
This Kit includes an AC/DC adapter (5V >= 2A) with a USB Type A connection along with a USB
Type-A to microUSB cable.
