3 MAXQ000 Evaluation Kit Detailed Description This evaluation kit must be used with the following documents: MAXQ000 Data Sheet ( MAXQ Family User s Guide ( MAXQ Family User s Guide: MAXQ000 Supplement ( The MAXQ000 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 MAXQ000 EV kit. The two boards that require power supplies are the MAXQ000 EV kit board and the serial-to-jtag interface board. The LCD daughterboard simply plugs into the MAXQ000 EV kit board and does not require its own power supply. Two different types of power supplies (which are not included with the MAXQ000 EV kit) are required to set up the configurations listed below. V, ±% 00mA DC regulated supply (mm, center-post, positive female connector) to power the serial-to-jtag interface board. V to V, 00mA DC supply (.mm, center-post, positive female connector) to power the MAXQ000 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 V to V DC wall supply (center post positive, at least 00mA capacity) to the J power plug of the MAXQ000 EV kit board. Note: When using two power supplies in this manner, the JU jumper on the MAXQ000 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 V, ±% regulated DC wall supply to the J power plug of the serial-to-jtag interface board. Connect the JH jumper on the serial-to-jtag interface board. Connect the JU jumper on the MAXQ000 EV kit board. Note: Do not connect a power supply to the J plug on the MAXQ000 EV kit when powering the boards in this manner. Running the MAXQ000 EV KIT Board from a Single Power Supply If the MAXQ000 has already been programmed using the JTAG interface, it is possible to disconnect the serial-to-jtag board and power up the MAXQ000 Evaluation Kit board on its own. This simply executes the previously loaded firmware, with no possibility of inapplication load or debugging. Connect a V to V DC wall supply (center post positive, at least 00mA capacity) to the J power plug of the MAXQ000 EV kit board. Evaluates: MAXQ000

4 MAXQ000 Evaluation Kit Evaluates: MAXQ000 Internal Power Rails The MAXQ000 EV kit board generates three internal power rails from the DC input power supply (from J or the serial-to-jtag board). Each of these supplies may be used to support up to 00mA of additional circuitry in the prototyping area. (Note: Test point TP is board ground.) The adjustable power supply, which can be measured at test point TP, provides an adjustable voltage between +.V and +.V. The level of this supply can be adjusted manually by turning potentiometer R with a screwdriver. The.V fixed power supply can be measured at test point TP. This voltage level can be used for V DDIO or V LCD, but not V DD. The.V fixed power supply can be measured at test point TP. This voltage level can be used for V DDIO, V LCD, or V DD. Table shows how the jumpers connect the MAXQ000 power rails to the on-board power supplies. Using the LCD Display To use the LCD daughterboard, it should be installed on the J connector of the MAXQ000 EV kit board. Pin on J should line up with pin of the LCD daughterboard J connector. Note that when the LCD daughterboard is installed correctly, it hangs off the top edge of the MAXQ000 EV kit board. When the LCD display is in use, V LCD should be connected to +.V. The LCD display on the LCD daughterboard is a static, -/ digit display. Figure 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., P.0 P., P.0 P., and P.0 P. for other uses. Additional Hardware Features Most of the additional hardware on the MAXQ000 EV kit board, such as the serial port, the MAX0, and the -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.
