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.

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

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)

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
