MAXQ2000 Evaluation Kit
The MAXQ2000 evaluation kit (EV kit) is a proven platform to conveniently evaluate the capabilities of the
MAXQ2000 low-power LCD microcontroller. The kit contains the MAXQ2000 with pins brought out to headers, a
JTAG programming interface, fixed and adjustable
power supplies, a DB-9 serial connector, an LCD display, and switches and LEDs to control and display
board operation. With the included software, serial-toJTAG interface board, and an RS-232 cable connected
to a personal computer, the kit provides a completely
functional system ideal for evaluating the capabilities of
the MAXQ2000.

Detailed Description
This evaluation kit must be used with the following documents:
• MAXQ2000 Data Sheet
(www.maxim-ic.com/MAXQ2000)
• MAXQ Family User’s Guide
(www.maxim-ic.com/MAXQUG)
• MAXQ Family User’s Guide: MAXQ2000 Supplement
(www.maxim-ic.com/MAXQ2k_sup)
The MAXQ2000 EV kit board and LCD display daughterboard are fully defined in the schematics provided in this
document. However, a short description of the major
components and connectors of the boards follows.
Power Supplies
There are three different ways to set up power supplies
when using the MAXQ2000 EV kit. The two boards that
require power supplies are the MAXQ2000 EV kit board
and the serial-to-JTAG interface board. The LCD
daughterboard simply plugs into the MAXQ2000 EV kit
board and does not require its own power supply.
Two different types of power supplies (which are not
included with the MAXQ2000 EV kit) are required to set
up the configurations listed below.
• 5V, ±5% 300mA DC regulated supply (25mm,
center-post, positive female connector) to power the
serial-to-JTAG interface board.
• 6V to 9V, 300mA DC supply (2.5mm, center-post,
positive female connector) to power the MAXQ2000
EV kit board.
Running Both Boards from
Separate Power Supplies
To run each of the boards from its own power supply,
connect supplies as follows.
• Connect a 5V, ±5% regulated DC wall supply to the
J2 power plug of the serial-to-JTAG interface board.
• Connect a 6V to 9V DC wall supply (center post positive, at least 300mA capacity) to the J1 power plug of
the MAXQ2000 EV kit board.
Note: When using two power supplies in this manner, the JU11 jumper on the MAXQ2000 EV kit board
must be DISCONNECTED.
Running Both Boards from a Single Power Supply
If the serial-to-JTAG interface board is being used, a
single power supply can be used to power both boards
as follows.
• Connect a 5V, ±5% regulated DC wall supply to the
J2 power plug of the serial-to-JTAG interface board.
• Connect the JH3 jumper on the serial-to-JTAG interface board.
• Connect the JU11 jumper on the MAXQ2000 EV kit
board.
Note: Do not connect a power supply to the J1 plug
on the MAXQ2000 EV kit when powering the boards
in this manner.
Running the MAXQ2000 EV KIT Board
from a Single Power Supply
If the MAXQ2000 has already been programmed using
the JTAG interface, it is possible to disconnect the serial-to-JTAG board and power up the MAXQ2000
Evaluation Kit board on its own. This simply executes
the previously loaded firmware, with no possibility of inapplication load or debugging.
• Connect a 6V to 9V DC wall supply (center post positive, at least 300mA capacity) to the J1 power plug of
the MAXQ2000 EV kit board.

Internal Power Rails
Using the LCD Display
The MAXQ2000 EV kit board generates three internal
power rails from the DC input power supply (from J1 or
the serial-to-JTAG board). Each of these supplies may
be used to support up to 100mA of additional circuitry
in the prototyping area. (Note: Test point TP1 is board
ground.)
• The adjustable power supply, which can be measured at test point TP2, provides an adjustable voltage between +1.8V and +3.6V. The level of this
supply can be adjusted manually by turning potentiometer R2 with a screwdriver.
• The 3.6V fixed power supply can be measured at
test point TP3. This voltage level can be used for
VDDIO or VLCD, but not VDD.
• The 2.5V fixed power supply can be measured at
test point TP4. This voltage level can be used for
VDDIO, VLCD, or VDD.
Table 1 shows how the jumpers connect the MAXQ2000
power rails to the on-board power supplies.
To use the LCD daughterboard, it should be installed on
the J3 connector of the MAXQ2000 EV kit board. Pin 1
on J3 should line up with pin 1 of the LCD daughterboard J1 connector. Note that when the LCD daughterboard is installed correctly, it hangs off the top edge of
the MAXQ2000 EV kit board. When the LCD display is in
use, VLCD should be connected to +3.6V.
The LCD display on the LCD daughterboard is a static,
4-1/2 digit display. Figure 4 shows how the segments
are mapped. If the LCD display is not needed, it can be
removed to free up port pins P0.0–P0.7, P1.0–P1.7,
P2.0–P2.7, and P3.0–P3.7 for other uses.
Additional Hardware Features
Most of the additional hardware on the MAXQ2000 EV
kit board, such as the serial port, the MAX1407, and the
1-Wire interface, can be enabled or disabled by setting
jumpers or DIP switches. Disabling unused hardware
frees up the associated port pins for other uses.
