Rev 2; 7/05 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.

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. _____________________________________________________________________ 3 Evaluates: MAXQ2000 Component List—LCD Display Daughterboard Evaluates: MAXQ2000 MAXQ2000 Evaluation Kit 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. Table 1.
