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.

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.

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-to­JTAG 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.
