MAX14502 Evaluation Kit
General Description
The MAX14502 evaluation kit (EV kit) provides a proven
design to evaluate the MAX14502 Hi-Speed USB-to-SD
card reader. The EV kit includes Windows
®
2000/XP-
and Windows Vista
®
-compatible software that provides
a simple graphical user interface (GUI) for exercising
the features of the MAX14502.
The MAX14502 EV kit has a built-in USB-to-I
2
C bridge,
allowing a PC to access the internal I
2
C registers of the
MAX14502, as well as providing the power for the EV kit.
The MAX14502 EV kit PCB comes with a
MAX14502AETL+ installed. The EV kit can also be used
to evaluate the MAX14500AETL+, MAX14501AETL+, and
MAX14503AETL+ by replacing the MAX14502AETL+,
and changing the crystal oscillator frequency according
to the device used or by applying an appropriate external
clock on the SMA connector. Contact the factory for free
samples of the MAX14500AETL+, MAX14501AETL+, and
MAX14503AETL+.

Note:
In the following sections, software-related items
are identified by bolding. Text in
bold
refers to items
directly from the EV kit software. Text in
bold and
underlined
refers to items from the Windows operating
system.
Procedure
The MAX14502 EV kit is fully assembled and tested.
Follow the steps below to verify board operation:
1) Visit
www.maxim-ic.com/evkitsoftware
to down-
load the latest version of the EV kit software,
14502Rxx.ZIP. Save the EV kit software to a tem-
porary folder and uncompress the ZIP file.
2)
Install the EV kit software on your computer by run-
ning the INSTALL.EXE program inside the tempo-
rary folder. The program files are copied and icons
are created in the Windows
Start | Programs
menu.
Verify that all jumpers are in their default positions,
as shown in Table 1.
Move slider switch SW1 to the on position.

17) Press the
Change To I2C Control
button to set the
MAX14502 in I
2
C control mode. Verify that
MAX14502 Connected on Address: 0xE0
is dis-
played on the status bar. All the I
2
C register con-
trols are available on the GUI, as shown in Figure 2.
18) Verify that the PC recognizes the USB mouse.
Detailed Description of Software
The software sets the MAX14502 in either simple or I
2
C
control mode.
In simple control mode, the user can set the device in
either pass thru or card reader mode. When the EV kit
is connected correctly, the software automatically moni-
tors the status of the
BERR
pin.
There are two tabs when the software works in I
2
C con-
trol mode.

Graphical View Tab
When the
Graphical View
tab (Figure 2) is selected, a
user has access to all of the I
2
C registers through the
on-board USB-to-I
2
C bridge.
The embedded picture shows the current mode of the
device. A command log window displays the read and
write operations on the MAX14502.
The status register (0x12) bit values are displayed in
the
Status
group box. When the solid circle is green, it
indicates a value of 1. When the solid circle is gray, it
indicates a value of 0.
When the INT pin is asserted, the solid circle beside the
INT Pin
label turns red. Otherwise, it is gray.
When the on-board USB-to-I
2
C bridge detects the pres-
ence of the MAX14502, the solid circle beside the
Ready
label turns green. If the EV kit is not connected
correctly, the circle is gray.
Press the
Query
button to read all the register values.
Press the
Load…
button to load the register settings
from a text file.
Press the
Save…
button to save the current register
settings to a text file.
Press the
Reset EVKIT
button to reset the EV kit,
including the USB re-enumeration on J6. The
MAX14502 is reset to its power-on-reset (POR) state.
Software Menu Bar
Select
File | Exit
to exit the application.
The
Help
menu item gives information about this EV kit
software.
Evaluates: MAX14502
Detailed Description of Hardware
The MAX14502 operates in pass thru and card reader
mode. The device can be controlled in two ways: sim-
ple control method and I
2
C control method.
The MAX14502 EV kit board provides a proven layout
for evaluating the device. The EV kit comes with one
MAX14502AETL+ installed.
Power Supplies
By default, the EV kit is powered by USB (J6). The dif-
ferent power supplies for the MAX14502 can be
applied according to user requirements. See Table 1
for possible power-supply configurations.
Alternative Input Clock
By default, the MAX14502 uses the on-board 19.2MHz
crystal oscillator output as the input clock. The user can
apply alternative clocks on the SMA connector (J5) and
set the shunt of jumper JU2 in the 2-3 position.
Reset MAX14502
The MAX14502 is reset by pressing and releasing
switch SW2.
Register View Tab
On the
Register View
tab (Figure 3), detailed names
and values of the registers are displayed.
Refer to the MAX14500–MAX14503 IC data sheet for
the detailed descriptions of all the registers available in
I
2
C control mode.
