The default device ordering number is SMM665BFC-266. It is programmed with the register contents as shown above
and tested over the commercial temperature range with a default VREF setting of 1.25V. Other standard external
VREF voltage settings that can be specified and tested are values of: 1.024, 1.225, 1.250, 2.048, 2.500, 3.000 or
3.300. The value is derived from the customer supplied hex file. New device suffix numbers are assigned for all non-
default VREF requirements. If other VREF values are required, please contact a Summit Microelectronics Sales
Representative.
Application Note 33 contains a complete description of the Windows GUI and the default settings of each of
the 154 individual Configuration Registers.
