A Low Cost Video Display System Using the Motorola 6811 Single-Chip Microcomputer.
Abstract
In 1972, Intel introduced the first central processing unit contained entirely on one chip, the 4004. Since then, continual improvements in semiconductor technology have enabled manufacturers to pack more and more components on a single chip. Now, in addition to the central processing unit, RAM, ROM, and peripheral devices can also be put on a single chip. This combination of central processing unit, RAM, ROM, and peripheral devices on a one chip is termed a single chip microcomputer. One of the most powerful single chip microcomputers available today is the Motorola 6811. The M6811 is the latest in the Motorola 68xx series of microprocessors-microcomputers. The M6811 features include an extended 6800 instruction set, 8K bytes of ROM, 512 bytes of EEPROM, 256 bytes of RAM, a 16-bit timer system, a serial communications interface (SCI), a serial peripheral interface (SPI), an eight channel analog-to-digital converter, and two 8-bit general purpose I/O ports.
