SMM205
Preliminary Information
DEVELOPMENT HARDWARE & SOFTWARE
The end user can obtain the Summit SMX3200
The Windows GUI software will generate the data and
send it in I2C serial bus format so that it can be directly
downloaded to the SMM205 via the programming
Dongle and cable. An example of the connection
interface is shown in Figure 8.

development. The SMX3200 system consists of a
programming Dongle, cable and WindowsTM 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).
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

Write Protect pin (WP#) which, when asserted, prevents writing to the configuration registers and EE
memory. In addition, there is a configuration register lock bit which, once programmed, does not allow the
configuration registers to be changed.
