Many years ago I was on a team designing a "smart sensor" box. The heart of it was an integrated precision A/D + 8051-compatible microcontroller chip from Analog Devices:
None of us has ever worked with microcontrollers before. It was my first ever job out of school. I don't think we would be able to deliver the product if the chip datasheet was not awesome. It had everything. Memory organization, registers, peripherals, board layout and grounding recommendations, ADC driving, etc.

Thank you, Analog Devices engineers.
