This EV kit should be used with the following documents: If the MAXQ615 kit is "free-running," that is, if you are running an application that has been previously loaded into the MAXQ615, and you do not need to use the loader or debugger, the board may be powered by a 5V DC wall supply connected to plug J1. The supply must be center post positive, DC 5V regulated, with a 250mA minimum capacity. * MAXQ615 IC data sheet * MAXQ615 user's guide * MAXQ615 EV kit data sheet These documents are included on the MAXQ615 EV kit CD, along with additional documentation and application notes. For the latest versions of the documents listed above, go to www.maximintegrated.com/MAXQ615. This document includes full schematics for the EV kit. Descriptions of the major sections and functions of the board follows. Power Supply The MAXQ615 EV kit can be powered in several ways. The board can be powered from the USB-to-JTAG adapter. The adapter provides a +5V DC supply. From this, an Maxim Integrated By removing jumper JU1 and connecting a power supply in its place, it is also possible to power the MAXQ615 from a DC bench supply or other regulated power source. In this case, any power-supply voltage compatible with the device(s) that will be powered may be used; refer to the MAXQ615 IC data sheet for more details on the allowable range for the power supply. Reset Pushbutton Pushbutton SW3 can be used to manually reset the MAXQ615. 3 MAXQ615 Evaluation Kit Evaluates: MAXQ615 Serial ADC The EV kit board includes a MAX1118 2-channel serial ADC (U2). By connecting the appropriate jumpers, the ADC can be connected to the MAXQ615, and is used to demonstrate the microcontroller's SPI communication interface. Each of the two ADC channels can be connected to the cathode of an on-board LED, and can be used to measure the voltage drop across the LED. The CD included with this EV kit includes sample code to demonstrate how to interact with the ADC. I2C Temperature Sensor The EV kit board includes a DS1775 I2C temperature sensor (U3). By connecting the appropriate jumpers, the temperature sensor can be connected to the MAXQ615, and is used to demonstrate the microcontroller's I2C communication interface. The CD included with this EV kit includes sample code to demonstrate how to interact with the temperature sensor. GPIO Pushbuttons and Indicator LEDs The two pushbuttons on the EV kit board can be connected to the MAXQ615 GPIO pins P1.0 and P1.1 by closing the associated jumper. See Table 1 for a description of the jumpers. If the pushbutton is pressed, it will pull the attached port pin low. The label indicating which port pin is tied to the switch is found on the board next to the switch. Switch SW2 pulls pin P1.0 (P10 label) low and switch SW1 pulls pin P1.1 low. The indicator LEDs (D5 and D6) next to each switch can also be connected to the port pin by closing the associated jumper (as detailed in the jumper table). The LED will be illuminated if either the GPIO pin connected to it is driven low, or the pushbutton switch is pressed. Jumper Function List Table 1 details the functions of the configurable jumpers on the EV kit board. Settings in the table marked with "*" indicate jumper placements that should be used for most normal operation (default settings). Table 1. Jumper Functions JUMPER SETTING EFFECT OF SETTING Open No on-board supply is connected to the VDD rail. To operate the EV kit, an external bench supply must be connected to JU1.2 or one of the VDD test points. Refer to the MAXQ615 IC data sheet for acceptable operating range information for the VDD supply. *Closed The +3.3V output from the on-board linear regulator (U1) is connected to the VDD rail. This supply will be used to power the MAXQ615 (as long as JU2 is closed), as well as the demo components U2 and U3 and the LEDs D5 and D6. JU1 JU2 Open *Closed The 5V pin on the JTAG cable is not connected to the on-board linear regulator supply input. If this position is used, then either a 5V external supply must be connected to J1 or a bench supply must be connected to JU1.2 or a VDD test point (with JU1 open) Closed The MAXQ615 EV kit may be powered directly through the USB-to-JTAG adapter's 5V supply (from the USB bus supply) Open Closed Open JU5 Closed Open JU6 Maxim Integrated The VDD pin on the MAXQ615 is connected to the on-board VDD power supply rail. Open JU3 JU4 No power is provided to the MAXQ615. This position should only be used when connecting a current meter between JU2.1 and JU2.2 to measure power consumption by the MAXQ615. Closed No effect The channel 1 input (CH1) on the ADC U2 is connected between LED D5 and R6 (see the EV kit schematic). This can be used to measure the diode drop across D5, for demonstration purposes. No effect The channel 0 input (CH0) on the ADC U2 is connected between LED D6 and R8 (refer to the kit schematic). This can be used to measure the diode drop across D6, for demonstration purposes. No effect The "start conversion on falling edge" pin on the MAX1118 (U2) is connected to pin P0.3 on the MAXQ615. Refer to the MAX1118 IC data sheet for more information on initiating A/D conversions and reading conversion results. 4 MAXQ615 Evaluation Kit Evaluates: MAXQ615 Table 1.

No effect The SCLK pin on the MAX1118 is connected to the SPI 0 interface pin SCLK (P0.2) on the MAXQ615. No effect Connects the SDA pin on the I2C temperature sensor (DS1775, U3) to the I2C SDA pin (P1.3) on the MAXQ615. Also connects the I2C bus pullup resistor (R3) to the SDA pin on the MAXQ615. No effect Connects the SCL pin on the I2C temperature sensor (DS1775, U3) to the I2C SCL pin (P1.2) on the MAXQ615. Also connects the I2C bus pullup resistor (R4) to the SCL pin on the MAXQ615. No effect Allows the green LED D5 to be controlled using the port pin P1.1 (driving the port pin low lights the LED). Also, pressing SW1 will both drive P1.1 low and cause the LED to light. No effect Allows the green LED D6 to be controlled using the port pin P1.0 (driving the port pin low lights the LED). Also, pressing SW2 will both drive P1.0 low and cause the LED to light. 5 4 3 2 J5V 1 RESET TP19 TP13 TP2 TP21 TP20 TP1 TP12 TP18 MH4 MT HOLE 125-200 MH3 MT HOLE 125-200 MH2 MT HOLE 125-200 MH1 MT HOLE 125-200 TP6 TP5 TP4 TP3 TP17 TP16 TP15 TP14 TP11 TP10 TP9 TP8 LED0 LED1 P00 P01 P02 P03 P04 P05 P06 P07 P10 P11 P12 P13 Add breadboard area in extra space using thru holes on 0.1 inch centers.
