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

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

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.

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.
