I have been getting the Maxim Analog Design Guides and similar mailings from Maxim, the latest one has one about an 8051 compatible chip with an 8 channel muxed 12 bit ADC and two 8 bit "PWM DACs". It has flash, which I really like. The copy said that there is an eval kit available. Apparently the mailing caught the web maintainers off guard as the chips don't show up even with the search. Presumably this would be a Dallas Semiconductor "cycle-enhanced" micro. (Maxim bought Dallas.) You could try their web site (www.dalsemi.com), although I don't see it offhand. The DS87C550 is pretty close, but the A-D is only 10 bits, and there are 4x8bit PWM outputs.
