I'm not aware of any PIC or AVR processors with on-chip DACs. ADI has 
some ADuC parts with DACs on-chip, but those are kind of oddball parts 
and probably not economical. There are some ARM processors from NXP that 
have DACs, but those are a different class of parts from those you 
mentioned.

Have you considered using a normal PIC/AVR with an off-chip SPI DAC? SPI 
DACs are inexpensive and easy to find.
