General Description
The MAXQMUSB-to-JTAG/1-WireMadapter is a
convenient way to interface either the JTAG or 1-Wire
port on MAXQ microcontrollers to a PC. The EV kit can
be used with compatible software tools running on a host
PC to load and debug code on programmable MAXQ
microcontrollers. The EV kit contains the MAXQ USB-
to-JTAG/1-Wire adapter, an interface cable, and a USB
Mini-B cable.

Detailed Description
Note: In the following sections, software-related items are
identified by bolding. Text in bold refers to items directly
from the EV kit software. Text in bold and underlined refers
to items from the Windows operating system.
The MAXQ USB-to-JTAG/1-Wire Adapter is designed
to operate as a USB-to-JTAG or USB-to-1-Wire adapter
between programming/debugging tools on the host PC
(such as MAX-IDE, MTK, or IAR Embedded WorkbenchM
IDE) and a programmable MAXQ microcontroller. The
MAXQ622 acts as a USB-to-UART converter and allows the
host PC to communicate with the MAXQ622 over a virtual
COM port. The MAXQ622 receives commands and data
from the PC and handles the task of either driving the four
JTAG communication lines (TCK, TMS, TDO, and TDI) or
driving the 1-Wire communication line (RST) that connect to
another MAXQ microcontroller on a separate EV kit board.
The adapter has two connectors. The first of these is a
standard mini-B USB connector that is used to connect
the adapter to a USB port on the host PC. The adapter
is powered directly over the USB cable. The second
connector is the standard 10-pin JTAG interface used by
all MAXQ microcontroller EV kits, allowing the adapter to be
connected to another MAXQ microcontroller using a 2x5-pin
header and 10-pin ribbon cable.
The driver software can be downloaded at www.
maximintegrated.com/evkit under MAXQUSBJTAGOW
EVKIT Software. Programming and debugging tools can
be found at www.maximintegrated.com/products/
microcontrollers/development_tools.cfm.
For more information on the adapter, refer to the MAXQ
USB-to-JTAG/1-Wire Adapter: User’s Guide.
