They were originally part of CiviSEPA, but they seem to be more volatile and need more tweaking depending on your CiviCRM version and your payment processor setup.
In order to facilitate faster development cycles, these payment processors can now be developed and versioned independently from CiviSEPA.
The module currently provides two SEPA payment processors:
SDDis the original payment processor implementationSDDNGis the 'next generation' processor, that was created to support membership and event payments.
