Detailed Description
This evaluation kit must be used with the following documents:
• MAXQ3210 Data Sheet
(www.maxim-ic.com/MAXQ3210)
• MAXQ Family User’s Guide
(www.maxim-ic.com/MAXQUG)
• MAXQ Family User’s Guide: MAXQ3210/MAX3212
Supplement (www.maxim-ic.com/MAXQ32xxSUP)
The MAXQ3210 EV kit board is fully defined in the schematics provided in the EV kit CD-ROM. However, a short description of the major components and connectors of the boards follows.
Power Supplies
There are three ways to set up power supplies when using the MAXQ3210 EV kit. The two boards that require power supplies are the MAXQ3210 EV kit board and the serial-to-JTAG interface 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 (center post positive) to the J2 power plug of the serialto-JTAG interface board.
• Connect a 9V, ±5% regulated DC wall supply (center post positive) to the J2 power plug of the
MAXQ3210 EV kit board, OR insert a 9V battery into clip J1 of the MAXQ3210 EV kit board.
• Connect a jumper across pins 1 and 2 of jumper
JU2 on the MAXQ3210 EV kit board.
Note: When using two power supplies in this manner, the JU1 jumper on the MAXQ3210 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 (center post positive) to the J2 power plug of the serialto-JTAG interface board.
• Connect the JH3 jumper on the serial-to-JTAG interface board.
• Connect the JU1 jumper on the MAXQ3210 EV kit board.
• Connect a jumper across pins 2 and 3 of JU2 on the
MAXQ3210 EV kit board.
Note: Do not connect a power supply to the J1 plug on the MAXQ3210 EV kit when powering the boards in this manner.
Running the MAXQ3210 EV Kit Board from a Single Power Supply
If the MAXQ3210 has already been programmed using the JTAG interface, it is possible to disconnect the serial-to-JTAG board and power up the MAXQ3210 EV kit board on its own. This simply executes the previously loaded firmware, with no possibility of in-application load or debugging.
• Connect a 9V, ±5% regulated DC wall supply (center post positive) to the J2 power plug of the
MAXQ3210 EV kit board, OR insert a 9V battery into clip J1 of the MAXQ3210 EV kit board.
• Connect a jumper across pins 1 and 2 of JU2 on the
MAXQ3210 EV kit board.
The power pins for the MAXQ3210 EV kit are connected to the on-board power supplies by jumpers as shown in Table 1.

Pins 1 and 2 connected
REGOUT is connected to the 5V supply from the JTAG board.
(No jumper) The power supply at J2 is not used.
Pins 1 and 2 connected
The J2 power supply (which should be 9V) is connected to the V BAT pin.
This configuration should only be used with the J1 battery clip empty.
JU2
Pins 2 and 3 connected
The J2 power supply (which should be 5V) is connected to the REGOUT pin. When using this configuration, the JU1 jumper must be disconnected and the J1 battery clip must be empty.
* Refer to the MAXQ3210 data sheet for the allowable range of supply at REGOUT.
Additional Hardware Features
Most of the additional hardware on the MAXQ3210 EV kit, such as the piezoelectric horn, LED and digital potentiometer, can be enabled or disabled by setting or removing jumpers. Disabling unused hardware frees up the associated port pins for other uses.
Using the RC Oscillator Clock Option
To run the MAXQ3210 EV kit using the RC oscillator, remove the crystal at Y1, close jumper JU3, and populate R3 and C4 with appropriate components. (Refer to the MAXQ3210 data sheet for appropriate resistor and capacitor values for a given frequency.)
Because the XT/
RC bit in the CKCN register is set to 1
(selecting crystal mode) upon power-up, the MAXQ3210 will always come out of power-up and attempt to run from an external crystal. If the RC circuit option is populated instead, the crystal oscillator does not start, and the
MAXQ3210 continues running on the internal ring oscillator (approximately 8kHz) until the loaded program firmware sets the XT/ RC bit to 0. If the MAXQ3210 is not loaded, it continues running from the internal ring indefinitely, which means it is running too slowly to communicate using the standard JTAG firmware.

WHEN CLOSED
The RC oscillator circuit may be used to drive the

R3 and C4 must be populated with appropriate components.

Port pin P0.5 (comparator input) is connected to the wiper pin of the MAX5160.
Port pin P1.6 is connected to pin U/ D of the MAX5160 digital potentiometer.
Port pin P0.7 (LED drive) is connected to the red LED D3.
If this occurs, you can communicate with the slow-running MAXQ3210 by loading the jtag_1kHz.hex file
(provided on the EV kit CD-ROM) into the serial-to-
JTAG board and then using MTK or MAX-IDE as usual.
Note that this version performs the master erase, loading, and debug operations much more slowly than usual due to the reduced communications speed, so as soon as you have loaded program firmware into the
MAXQ3210 that sets the XT/ RC bit to 0 upon startup, you can reload the normal serial-to-JTAG board firmware to go back to normal tools operation.
