SMM151/152
Preliminary Datasheet
APPLICATIONS INFORMATION (CONTINUED)
The end user can obtain the Summit SMX3200
programming system for device prototype development.
The SMX3202 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 SMX3202 is available from the
website (www.summitmicro.com).
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 SMM151/152 via the programming
Dongle and cable. An example of the connection
interface is shown in Figure 9.
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.
The SMX3202 programming Dongle/cable interfaces
directly between a PC’s USB port and the target
application. The device is then configured on-screen via
an intuitive graphical user interface employing drop-
down menus.

Figure 9– SMX3202 Programmer I2C serial bus connections to program the SMM151/152. The SMM151/152 have
a Write Protect pin (WP input) 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.
