DEVELOPMENT HARDWARE & SUPPORT
The end user can obtain the Summit SMX3200
programming system for device prototype development.
The SMX3200 system consists of a programming Dongle,
cable and Windows GUI software. It can be ordered on the
website or from a local representative. The latest revisions
of all software and an application brief describing the
SMX3200
is
available
(
www.summitmicro.com
).
from
the
website
The SMX3200 programming Dongle/cable interfaces
directly between a PC’s parallel port and the target
application. The device is then configured on-screen via an
intuitive graphical user interface employing drop-down
menus.
The Windows GUI software will generate the data and send
it in I
2
C serial bus format so that it can be directly
downloaded to the SML2120 via the programming Dongle
and cable. An example of the connection interface is shown
in Figure 10.
When design prototyping is complete, the software can
generate a HEX data file that should then be transmitted to
Summit for approval. Summit will then assign a unique
customer ID to the HEX code and program production
devices before the final electrical test operations. This will
ensure proper device operation in the end application.

C serial bus connections to program the SML2120. For the SML2120, the
AM# pin must be high in order to program the device. Normally, SDA and SCL signals require on board pull-up
resistors, however, the SMX3200 has internal pull-up resistors. D1 is needed between the Dongle Supply and the
VDD pin so that there will be no contention between the two supplies. C1 is for noise bypassing. Note, AM# must
be high for programming, it can be pulled high externally or by the SMX3200 programmer. AM# must be low for
auto-monitor mode operation.
