evaluates: maxq2000 maxq2000 evaluation kit _____________________________________________________________________ 3 detailed description this evaluation kit must be used with the following doc- uments: maxq2000 data sheet ( www.maxim-ic.com/maxq2000 ) maxq family user? guide ( www.maxim-ic.com/maxqug ) maxq family user? guide: maxq2000 supplement ( www.maxim-ic.com/maxq2k_sup ) the maxq2000 ev kit board and lcd display daughter- board 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, ?% 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, ?% 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 posi- tive, at least 300ma capacity) to the j1 power plug of the maxq2000 ev kit board. note: when using two power supplies in this man- ner, 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, ?% 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 inter- face 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 seri- al-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 in- application load or debugging. connect a 6v to 9v dc wall supply (center post posi- tive, at least 300ma capacity) to the j1 power plug of the maxq2000 ev kit board. designation qty description supplier part c1?4 4 empty capacitor footprint (0805) j1 1 2 x 26, 0.1?spaced socket 3m 929975-01-26 r1?3 3 empty resistor footprint (0805) u1 1 static, 3v, 4-1/2 digit display lcd varitronix vi-502-dp-rc-s component list?cd display daughterboard
evaluates: maxq2000 internal power rails 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 mea- sured at test point tp2, provides an adjustable volt- age between +1.8v and +3.6v. the level of this supply can be adjusted manually by turning poten- tiometer r2 with a screwdriver. the 3.6v fixed power supply can be measured at test point tp3. this voltage level can be used for v ddio or v lcd , but not v dd . the 2.5v fixed power supply can be measured at test point tp4. this voltage level can be used for v ddio , v lcd , or v dd . table 1 shows how the jumpers connect the maxq2000 power rails to the on-board power supplies. using the lcd display 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 daughter- board j1 connector. note that when the lcd daughter- board is installed correctly, it hangs off the top edge of the maxq2000 ev kit board. when the lcd display is in use, v lcd 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?0.7, p1.0?1.7, p2.0?2.7, and p3.0?3.7 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. maxq2000 evaluation kit 4 _____________________________________________________________________ jumper setting effect ju1 (no jumper) v dd is floating (drive from bench supply)* ju1 pins 1 and 2 connected v dd is driven by +2.5v fixed supply ju1 pins 2 and 3 connected v dd is driven by adjustable supply* ju2 (no jumper) v ddio is floating (drive from bench supply) ju2 pins 1 and 2 connected v ddio is driven by +3.6v fixed supply ju2 pins 2 and 3 connected v ddio is driven by adjustable supply ju3 (no jumper) v lcd is floating (drive from bench supply) ju3 pins 1 and 2 connected v lcd is driven by +3.6v fixed supply ju3 pins 2 and 3 connected v lcd is driven by adjustable supply * refer to the maxq2000 data sheet for the allowable range of the v dd supply. table 1. power-supply jumper settings
