cable and software that have been developed to operate
with a standard personal computer. The programming
cable interfaces directly between a PC’s parallel port and

it in I2C serial bus format so that it can be directly
downloaded to the SMS46 via the programming Dongle
and cable. An example of the connection interface is
shown in Figure 6.
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
devicesbeforethefinalelectricaltestoperations. Thiswill
ensure proper device operation in the end application.
