<td valign="top" height="5" colspan="2" width="596">The DK3420 evaluation board will
allow you to evaluate the full-speed USB capabilities of the uPSD3400 Turbo Plus series of
8-bit MCU. As you saw, this simple board effectively emulates a small USB flash
disk. The turbo uPSD3400 device not only manages the USB interface, but uses its
large main Flash memory for the Flash disk storage. The secondary Flash memory
contains the firmware the MCU is executing. <p>To allow you to further evaluate the
uPSD3400 and the corresponding tools, you'll need a JTAG-USB debugging adaptor.
Either the Keil ULINK-UPSD, or the Raisonance RLINK-ST works with our uPSD devices.
Both are available for purchase on our website, and both adaptors ship complete with a
code-limited version of the respective companies' IDE including the compiler, linker,
assembler and debugger. The Raisonance Rkit IDE (RIDE) debugger fully supports
code developed in RIDE as well as code generated from most other 8051 compilers with no
limit on code size. <a href="index.htm#top"><img src="images/top.jpg" alt="top.jpg (801 bytes)" align="right" border="0" WIDTH="18" HEIGHT="18"></a></td>

<td valign="top" height="5" colspan="2" width="596">You will be able to compile a sample
project, program the DK3420, and then 'debug' the program running on the DK3420. When
debugging you will be able to single step in Assembly or C, run to breakpoints (code or
data),and even trace program execution of this project as it runs on the DK3420. <p>The
DK3420 has sockets for most of the uPSD3400 peripherals (see included DK3420 schematics
for details) and can even be used as a low cost development board in conjunction with
either one of the JTAG-USB debugging adaptors for the uPSD. </p>
<p><a href="http://mcu.st.com/contentid-60.html">Please visit our website for more details
and to purchase your RLINK-ST or ULINK-UPSD for $59.</a></p>
<p>Customers that purchase an RLINK-ST are also able to upgrade to full versions of RIDE
at discounted prices. </p>
<p>ST has worked closely with both Raisonance and Keil such that both companies' IDEs have
been adapted to support the advanced debug and programming innovations in the uPSD3400
Turbo Plus series. These innovations include JTAG In System Programming and JTAG Debug to
allow programming and real-time debug. To further help software development, additional
enhancements have been added for the uPSD3400 family including:</p>
