What was the primary architectural focus of the TI TMS1000 and Intel 8048 compared to the 4004?

Answer

System integration and I/O capability.

The evolution towards microcontrollers prioritized integrating necessary control features and I/O onto the chip to create a self-contained system dedicated to embedded tasks, rather than focusing on general-purpose computational strength.
