The earliest microprocessors, and some famous kinds of microprocessors still being made, fill the entire chip, and so require external RAM and ROM/FLASH memory.

+ | Microcontrollers are little computers on a single Die/Package. The computer includes a CPU core, RAM, ROM/FLASH, and peripherals including UARTS, A/D converters, SPI, and I2C. Microcontrollers differ from microprocessors in that the microporcessors generally have bigger more powerful central processing units, but need support chips for ram, rom and other peripherals. Most modern microcontrollers use FLASH ram instead of a ROM so they can be programmed over and over. Many modern microcontrollers allow self-flashing to enable bootloading or a firmware update without pulling the chip from the circuit or using a programmer/debugger. Microcontrollers tend to be more optimizated for writting in assembly then PCs, but C and less so Basic are becoming the standard programming languages. | ||
