1. Introduction

The MCIMX53SMD Board Hardware User’s Guide is a user manual that describes the design and usage of the
MCIMX53SMD board, which is a printed circuit board (PCB) based on Freescale Semiconductor’s i.MX53
Applications Processor (AP). This guide specifies the basic architecture of the MCIMX53SMD board and
explains the design and purpose of each component of the board. It also tells how developers can use the
MCIMX53SMD board in their various development works.

1.1. MCIMX53SMD Board Overview

The MCIMX53SMD board is an i.MX53 platform that provides many widely used features of the i.MX53
Applications Processor in a tablet package. Being a complete development platform, the MCIMX53SMD board
has a design structure that is almost similar to the more complex i.MX53 platforms. This helps developers to
port code developed on the MCIMX53SMD board to other boards with minimal effort. Developers can use the
MCIMX53SMD board to test the features of the i.MX53 Applications Processor, before investing a large
amount of money or resources in more specific designs. Figure 1-1 shows an MCIMX53SMD board with a
debug card and a display.

3.5. Mini-HDMI Connector (J25)

The mini-HDMI connector is used as HDMI output of MCIMX53SMD board. The power source for the HDMI
Bridge SiI9022 is DCDC_3V3_BB, and the power source for mini-HDMI connector is DCDC_5V_BB.

3.6. SD Card Slot (J13)

The SD Card slot is a 5-in-1 SD/MMC connector that acts as memory media slot. The power source for the SD
Card Slot is the auxiliary DCDC buck (DCDC_3V3_BB). The SD Card slot can be configured as the boot source
with an alternate boot option setting. It can also be configured for either SD or MMC card operation (see the

Boot Mode Operations and Selections section). The SD Card Slot supports full 4-bit parallel data transfers and

can support SDIO cards (such as, WiFi and BT) designed to fit in a standard SD card slot.

3.7. SATA Connector (J5)

The SATA connector provides a means to connect an external SSD SATA drive to the MCIMX53SMD board.
Power for the SATA drive needs to be supplied by SATA_5V and SATA_3V3. The developer can use boot
configure to boot the SATA drive.

3.8. VGA Dock (J131)

A Dock with VGA signal is on the MCIMX53SMD board. VGA is the output that comes directly from the i.MX53
processor with minimum external components required. Power for the TVE module of the i.MX53 processor is
supplied by VLDO7 of the PMIC and is set to 2.75V. If VGA output is not desired, the PMIC can be programmed
to turn off VLDO7 to conserve power. The VGA output supports a variety of video formats up to 150
Megapixels per second. Level shifters are required on the Horizontal and Vertical Synchronization signals as
well as the VGA I2C communications signals in order to meet VGA specifications. Meanwhile, Audio LINEIN and
LINEOUT are supported on the Dock. The Audio LINEIN and LINEOUT are from SGTL5000 on MCIMX53SMD
board. Another feature on Dock is USB.

3.9. LVDS Video Output (J28, J29)

The LVDS module of the i.MX53 processor is connected to two 30-pin LVDS connectors. Both connectors are
pinned out on the MCIMX53SMD board, though the i.MX53 processor is capable of outputting to two separate
LVDS displays. The pin outs on the LVDS connector match the optional cable and 10” HannStar LVDS display

Freescale Semiconductor MCIMX53SMD Board Hardware User’s Guide, Rev. 0 15

(both can be purchased from Freescale). The single LVDS connector will support video formats up to 165
Megapixels per second. The power source for the LVDS module is a switchable output of the VBUCKPERI DCDC
converter. This rail is shared with the SATA module and the USB module. If these modules are not used, the
PMIC can be programmed to turn off power to these three modules, without affecting the 2.5V supplies to
other portions of the i.MX53 processor.

3.10. Ethernet (on Debug Board)

The i.MX53 processor Fast Ethernet Module outputs RMII formatted signals to an external Ethernet PHY. The
processor is capable of 10/100 Base-T speeds. The MCIMX53SMD board uses the SMSC LAN8720A Ethernet
Transceiver in a QFN-24 package. The Ethernet IC is powered by a 3.3V supply from DCDC_3V3_BB. The output
of the Ethernet PHY is connected to the debug board.

3.11. Dual USB Host Connector (J31, J32)

The USB module of the i.MX53 processor provides a high speed USB PHY that is connected to a USB HUB
(USB2514). Two of the USB ports are dedicated to USB HOST. Both jacks receive 5V power from DCDC_5V
through a power monitor that can be controlled by software.

3.12. Micro-B USB Device Connector (J34)

The micro USB connector is connected to the USB OTG PHY on the i.MX53 processer and supports full OTG
function.

3.13. Audio Input/Output (P1/J130/CON1)

Analog audio input and output are provided by Freescale’s Low Power Stereo Codec, SGTL5000. The audio

codec is connected to the i.MX53 processor through four-wire I2S communications, utilizing the AUDMUX5
port of the processor. The audio codec’s Headphone Amp provides up to 58 mW output to 16Ω headphones at
a typical SNR of 98 dB and THD+N of -86 dB. Typical power consumption is 11.6 mW. In addition, the audio
codec can perform several enhancements to the output, including virtual surround, added bass, and three
different types of equalization. The Microphone Input module of the Stereo Codec is also used, while the
microphone is applied on the MCIMX53SMD board. A Headphone Jack (J130) and Speaker Connector (CON1)
are on the MCIMX53SMD board. A 3.5 mm Headphone with plug-in detect is supported. Two speakers with 8Ω
impedance rating and 1W power rating are attached through a power amplifier (TS4984IQT).

3.14. 15V Power Connector (J35)

A 2.0 mm x 6.5 mm barrel connector is used which should fit standard DC Plugs with an inner dimension of 2.1
mm and an outer dimension of 5.5 mm. If a secondary power supply is used, it should not supply more than
15V power at 3A output. If the PMIC senses too high voltage at the connector input, it will turn off to protect
the MCIMX53SMD board. If a Wall Power Supply is connected to the MCIMX53SMD board, the red 15V power
LED indicator will light.

3.15. Mini-PCIe Connector (J15, J18)

Two mini-PCIe connectors are on the MCIMX53SMD board. One for 3G modem, the other is for WiFi/BT. The
MCIMX53SMD board provides just a standard mini-PCIe slot for 3G Modem. So, the developers can use a 3G
Modem of their choice. For the WiFI/BT module, the MCIMX53SMD board uses the module based on the
Atheros. The module pin map is not compatible with the standard mini-PCIe. Therefore, care must be taken to
plug the module to the right mini-PCIe slot.

16 MCIMX53SMD Board Hardware User’s Guide, Rev. 0 Freescale Semiconductor

3.16. CMOS Sensor Connector (J12)

The MCIMX53SMD board supports a 5 Megapixels CMOS Camera. The CMOS module is based on the
OmniVision chipset, OV5642. Auto Focus (AF) function is not supported on the board. The developer can
choose another CMOS module on their project, if the pin map is compatible. The MCIMX53SMD board uses
CMOS connector, FX12B-40P-0.4SV, from HIROSE.

3.17. Debug UART Connector (on Debug Board)

UART1 of the i.MX53 processor is connected to an RS-232 output to be used as a debug output for the
developer. The Transmit (TX) and Receive (RX) signals are sent through two 1.8V to 3.2V level shifters to
convert the logic signal voltages to the correct values for the Sipex SP3232 RS-232 transceiver. The CTS and
RTS signals are not used on the MCIMX53SMD board. The RS-232 transceiver receives its power from the
external 3.3V LDO regulator. If the output of the regulator is turned off for power savings measures, debug
output will be lost.

If the designer wishes to use the port as an Applications UART Port, changes can be made in software to
reconfigure the port. A male-to-male gender changer can be used to properly convert the port.

To access the debug data output during development, connect the Debug UART Connector to a suitable host
computer and open a terminal emulation program (that is, Teraterm or HyperTerminal). Proper settings for
the terminal program are:

BAUD RATE: 115,200
DATA: 8 bit
PARITY: None
STOP BIT: 1-bit
FLOW CONTROL: None

3.18. JTAG Connector (on the Debug board)

A standard 20-pin ARM JTAG connector is provided on the MCIMX53SMD board. Logic signals to the JTAG
connector are 1.8V signals. A 1.8V reference signal is provided to pin one of the connectors so that the
attached JTAG tool can automatically configure the logic signals for the right voltage. If the JTAG tool does not
have an automatic logic voltage sense, then, make sure that the tool is configured for 1.8V logic.

JTAG tools that have been specifically tested with the MCIMX53SMD board are:

CodeWarrior (Freescale)
JTAG Commander (Macraigor)
J-Link (Segger/Codesourcery)
J-Link (IAR)

3.19. Expansion Header (J78)

A 120-pin Expansion Port Header is provided on the MCIMX53SMD board which can be used with many
optionally expansion boards available from Freescale, or with custom designed boards made be the developer.
The Expansion Port makes the following features of the i.MX53 processor available for being used on a custom
built expansion card:

Two Inter-Integrated Circuits (I2C): I2C1, I2C2
24-bit data and display control signals
Resistive Touch Screen Interface
Various voltage rails

Freescale Semiconductor MCIMX53SMD Board Hardware User’s Guide, Rev. 0 17

3.20. Function Buttons

The MCIMX53SMD board provides two user interface buttons, which are discussed below.

3.20.1. POWER Button

In the ‘Power Off’ state, momentarily pressing the POWER button will begin the PMIC power up cycle. The
PMIC supplied voltage rails will come up in the proper sequence to power the i.MX53 processor. When the
processor is fully powered, the boot cycle will be initiated.

In the ‘Power On’ state, momentarily pressing the POWER button will send a signal to a GPIO port for user
defined action, but will not initiate a hardware shutdown.

In the ‘Power On’ state, holding the power button down for more than 5 seconds will result in the PMIC
initiating a shutdown to the ‘Standby’ power condition. This will also be the result from the ‘Power Off’ state
as the PMIC will transition into the ‘Power On’ state and will still see the POWER button as held down.

3.20.2. RESET Button

Pressing the RESET button in the ‘Power On’ state will force the i.MX53 processor to immediately turn off, and
reinitiate a boot cycle from the Processor Power Off state. The RESET button has no effect on the PMIC or the
voltage rails.
Pressing the RESET button when the MCIMX53SMD board is powered off will have no effect.

3.21. User Interface LED Indicators

There are eight LED status indicators located next to the micro SD card connector. These LEDs have the
following functions:

15V: The 15V status LED (D29) is a Red LED connected directly to the 15V power rail. This LED indicates

that 15V wall power is being properly supplied to the MCIMX53SMD board.

CMOS Run/Charger Now: This status LED (D27) is a Red LED gated by the EIM_D30 (W4) GPIO pin with

two functions. One of these functions is for CMOS running status, the other is dedicated to the status
of charger.

USER Debug/Charger Done: This LED (D32) is a Green LED gated by the PATA_DATA1 (L3) GPIO pin

with two functions. One of these functions is for User debug, the other is dedicated to the status of
charger.

3G Status: The 3G modem status LED (D19) is an Orange LED gated 3G WWLAN pin.
WiFi/BT: The WiFi/Bt status LED (D9, D10). D9 is a Green LED, and as WLAN Active status. D10 is a Blue

LED, and as BT Active status.

3.22. Li-ION Battery Connector (J12)

The MCIMX53SMD board provides a footprint (J12) that can be used to solder a five-pin connector. The board
has a three-cell Li-ION battery of ~40 Wh. The developer can change it, if needed, and must follow the pin map
of the connector.

3.23. Back-Up Coin Cell Posts (BT1)

For proper operation, the coin cell posts should be soldered direction to the MCIMX53SMD board. The
DA9053 PMIC will charge the coin cell when Battery or Wall Power is available. When Battery or Wall Power is
removed, the coin cell will provide power only to the RTC power rail (VLDO1), supplying power to the i.MX53
processor. The length of time a coin cell can power the RTC subsystem may vary.

4. MCIMX53SMD Board Connectors

The MCIMX53SMD board provides a number of connectors for a variety of inputs and outputs to and from the
board. The following subsections describe these connections in detail.

4.1. Wall 15V Power Jack (J35)

The 15V at 3A AC-to-DC power supply that comes with the MCIMX53SMD board is plugged into the Power
Jack (J35) on the board, as shown in Figure 4-1. To avoid damage to the board, it is recommended not to use
unofficial power.

4.2. SD Card Connector (J13)

The MCIMX53SMD board has one 4-bit SD/MMC connector that can be used for memory, or for third-party
SDIO type cards, such as WiFi or Bluetooth. The SD Card Connector (J13) connects a 4-bit parallel data bus to
the SD1 port of the i.MX53 processor. The SD Card Connector receives power from DCDC_3V3. The board can
be modified to support booting from this connector. See the Boot Mode Operations and Selections section to
learn how to modify the board. The SD Card Connector is not spring loaded, so pushing the card into the slot
will not initiate an action to disengage the SD Card. The SD Card is inserted facing up at the location shown in

4.5. Micro-B USB Device Connector (J34)

The MCIMX53SMD board has one micro-B USB device connector that can be used to connect the
MCIMX53SMD board to a USB Host computer. The micro-B connector is connected to the high-speed (HS) USB

2.0 OTG module of the i.MX53 processor. When a 5V supply is provided to the micro-B connector (from the
USB Host), then, the i.MX53 processor will configure the OTG module for device mode. This will prevent the
lower USB Host port from operating correctly. The 5V power provided by the attached USB Host is only used
by the i.MX53 processor for sensing that the host is present. The MCIMX53SMD board will not draw power
from the connected USB Host and will not operate without a 5V DC power source or charged Li-ION battery.
The micro-B connector is keyed and will not accept a micro-A plug from a cable. A micro-B to USB-A cable is
supplied as part of the MCIMX53SMD board kit and can be inserted into the micro-B USB connector at the
point shown in Figure 4-5.

the debug board. It includes JTAG, RS-232, and Ethernet. It is easy to use to debug the board for SW engineer.
A debug board is supplied as part of the MCIMX53SMD board kit and can be inserted into the debug
connector at the point shown in Figure 4-7.

A standard Cat-V Ethernet cable is attached to the debug board at the Ethernet. The connector allows the
Ethernet IC to auto configure the port for the correct connection to either a switch or directly to a host PC on a
peer-to-peer network. It is not necessary to use a crossover cable when connecting directly to another
computer. A Cat-V Ethernet cable is supplied as part of the MCIMX53SMD board kit.

To connect a host PC to the MCIMX53SMD board to receive debugging information, a Null Modem serial cable
is required and supplied with the MCIMX53SMD board kit. For newer generation computers that do not have
a serial port, a USB-to-Serial cable can be used. There is no need for any special cabling to support debug
information output.
The debug board contains a standard 20-pin ARM JTAG connector for advanced debugging with a third-party
emulator. The header is configured to be used with 1.8V data signals. The developer should exercise caution
when selecting the appropriate debugging tools. If an emulator set for 3.3V power and data is connected to
the MCIMX53SMD board, the i.MX53 processor will be damaged.
