General Description
The MAXQ1004 evaluation kit (EV kit) provides a proven
platform for conveniently evaluating the capabilities
of the MAXQ1004 1-WireM/SPI™ authentication micro-
controller. The EV kit includes the MAXQ1004 EV kit
board, which contains an on-board USB-to-JTAG loader/
debugger interface using the MAXQ610 microcontroller,
off-board connectors for the 1-Wire and SPI communica-
tions interfaces, two GPIO-controlled pushbuttons and
two LED indicators for application use, and headers
providing access to all I/O pins on the MAXQ1004. With
the included software and a USB cable connected to a
WindowsM PC, the EV kit provides a complete, functional
system ideal for developing and debugging applica-
tions as well as evaluating the overall capabilities of the
MAXQ1004 RISC microcontroller.

Detailed Description of Hardware
Power Supply
The EV board should normally be powered by connect-
ing a standard USB interface cable (A-to-mini-B) from
connector CN1 on the EV board to a PC. This allows the
board to draw power directly over the +5V supply on
the USB port. The built-in +3.3V linear regulator on the
FT232RL IC (U1) is normally used to generate the VDD
power rail used by the MAXQ1004 and the MAXQ610.
If the MAXQ1004 kit is “free-running,” that is, the user is
running an application that has been previously loaded
on the MAXQ1004, and does not need to use the loader
or debugger, it is not necessary to connect the USB
cable. In this configuration, the EV kit can be powered
by connecting a regulated DC bench supply to pin JH3.2
(MAXQ1004 VDD/AVDD). Refer to the MAXQ1004 IC
data sheet for allowable power-supply range values.
GPIO Pushbuttons and Indicator LEDs
The two pushbuttons on the bottom side of the EV kit
(SW2 and SW3) are connected to the MAXQ1004 GPIO
pins P0.1 (SW3) and P0.0 (SW2). If the pushbutton is
pressed, it pulls the attached port pin low. The label indi-
cating which port pin is connected to the switch is found
on the board below the switch.
If jumper JH4 is closed, the GPIO pin P0.2 can be used
to drive LED DS1. If P0.2 is driven low, then LED DS1
lights; otherwise, it is dark.
If jumper JH5 is closed, the GPIO pin P0.3 can be used
to drive LED DS2. If P0.3 is driven low, then LED DS2
lights; otherwise, it is dark.

MAXQ610 and the JTAG Loader/
Debug Interface
The MAXQ610 microcontroller (U4) is preloaded with
interface firmware that provides a link between the
JTAG loader/debug interface on the MAXQ1004 and the
serial port output from the FTDI USB-to-serial bridge IC.
This firmware handles commands that are transmitted
by application development and debugging software
running on the PC, such as MTK, MAX-IDE, or IARM
Embedded Workbench environment.
Under normal circumstances, the firmware in the
MAXQ610 should not be altered. If it is necessary to
update or change the JTAG loader/debug firmware, the
standard MAXQ JTAG loader tools (such as MTK) can
be used to do so, using any of the available MAXQ JTAG
interface boards and the P2 JTAG connector.
FTDI USB-to-Serial Bridge
The FTDI USB-to-serial interface IC (U1, FT232RL) pro-
vides an interface between a virtual COM port running
on the PC and the MAXQ610 over a USB-to-serial link.
Refer to the MAXQ1004-KIT Quick Start Guide for details
on installing and configuring the FTDI drivers required
for this interface to operate correctly. The FT232RL also
provides the +3.3V regulated supply (used by all devices
on the EV kit) and a direct 12MHz digital clock (used by
the MAXQ610 only).
Reset Pushbutton
Pushbutton SW1 can be used to manually reset the
MAXQ1004. Normally, this should only be done when
the part is free-running, that is, when the loader/debug
interface is not in use, or when the part is running with a
breakpoint set in the debugger (not during step-by-step
tracing mode). Triggering a manual reset when code
is being loaded to the part or during active debugging
mode can cause the development environment to lose
communications with the part, which means that the proj-
ect session may have to be restarted and the application
reloaded in order to continue.
1-Wire Interface and Power Over 1-Wire
The EV kit can optionally be configured to operate using
a “parasite power” supply mode, where all power to
operate the MAXQ1004 is drawn from the 1-Wire signal
line. Using this supply scheme, power is “captured” from
the 1-Wire line during high signal periods using diode
DN1, and energy is stored in capacitor C4. This supply
voltage (which is at the 1-Wire line voltage) is regulated
down to +2.5V by linear regulator U2.
To configure the MAXQ1004 to run using this power sup-
ply, set JH3 to pins 2+3 (VDD+V25). However, this only
powers the MAXQ1004. The MAXQ610 (and the accom-
panying FTDI device) does not operate from this supply,
which means that the application code must already be
loaded into the MAXQ1004 (the MAXQ1004 must be
free-running).
There are additional considerations when using this type
of power supply. If a standard 1-Wire pullup is being
used, the energy stored in the parasite power capacitor
can only power the MAXQ1004 for a brief time. The length
of time that the MAXQ1004 can run before exhausting the
parasite power supply varies depending on the operating
frequency and activity of the MAXQ1004, as well as the
resistance of the pullup on the 1-Wire line.

Features of 1-Wire® Devices.

Jumper Function List
Table 1 details the functions of the EV kit's configurable
jumpers. Settings marked with “” indicate jumper place-
ments that should be used for most normal operation
(default settings).
Table 1. Configurable Jumper Setting Functions
JUMPER SETTING EFFECT
JH1
Open No supply is connected to the VDD pin on the MAXQ1004. This setting should not
normally be used.
Closed The VDD on-board supply (normally +3.3V) is connected to the VDD pin on the
MAXQ1004.
JH2
Open No supply is connected to the AVDD pin on the MAXQ1004. This setting should not
normally be used.
Closed The VDD on-board supply (normally +3.3V) is connected to the AVDD pin on the
MAXQ1004.
JH3
Open No power supply source is connected to the VDD on-board supply. If this setting is used,
an appropriate DC bench supply should be connected to pin JH3.2 (VDD) and GND.
Closed
(1+2, MVDD+VDD)
The VDD on-board supply is powered by the +3.3V regulated output from the FT232RL
IC (which is also the MVDD supply used by the MAXQ610).
Closed
(2+3, VDD+V25)
This setting should not normally be used, unless the parasite power option is required.
This setting leaves the MAXQ610 and the FT232RL unpowered.
JH4 Open LED DS1 is disabled.
Closed LED DS1 can be lit by driving GPIO pin P0.2 low.
JH5 Open LED DS2 is disabled.
Closed LED DS2 can be lit by driving GPIO pin P0.3 low
P3 N/A Not a configuration jumper. Pin P3.1 provides access to the 1-Wire data line on the
MAXQ1004.
P4 N/A Not a configuration jumper. Pin P4.2 provides access to the AN0 pin (ADC input) on
the MAXQ1004.
