The answer is, yes, and before the 1980s.

For example, Nintendo released the NES in 1983, and the Ricoh 2A03/2A07 microprocessors integrated an unlicensed MOS Technology 6502 core derivative with a programmable sound generator which also contained a simple DMA system.

And the MOS 6510 itself is a 6502 CPU integrated with an I/O port. I don't know the exact release date but it was already used on C64, released in 1982.

The Motorola 6800 was also integrated with memory and sold as 6802, in 1977. The 6801 integrated 6846 so it had ROM, IO, and timers, released in 1977 or 1978.

Intel also released their first microcontroller series, the MCS-48, in 1976.

The answer is, yes, and before the 1980s.

It appears the first ever microcontroller was TI TMS1000, introduced in 1974.
