SMS64
Preliminary
DEVELOPMENT HARDWARE & SOFTWARE
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
(www.summitmicro.com).
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 SMS64 via the
programming Dongle and cable. An example of the
connection interface is shown in Figure 2.
When design prototyping is complete, the software
can generate a HEX data file that should 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 SMS64. Normally SDA and SCL
signals require on board pull-up resistors, however, both the SMS64 and the SMX3200 have internal pull-up
resistors. D1 is needed between the Dongle Supply and Vcc_Cap so that there will be no contention
between the two supplies. C1 is for noise bypassing.
