The Motorola 6809 was originally produced in 1 MHz, 1.5 MHz (68A09) and 2 MHz (68B09) speed ratings. Faster versions were produced later by Hitachi. With little to improve, the 6809 marks the end of the evolution of Motorola's 8-bit processors; Motorola intended that future 8-bit products would be based on an 8-bit data bus version of the 68000 ...
The 6309 is fabricated in CMOS technology, while the 6809 is an NMOS device. As a result, the 6309 requires less power to operate than the 6809. Although it is a dynamic design (the datasheet [3] specifies a 500 kHz minimum clocking frequency and it will lose its state when the clock speed is too low), it can be paused for up to 15 cycles.
The MC6809 was the most advanced 8-bit microprocessor Motorola produced. It had a new instruction set that was similar to the 6800 but abandoned op-code compatibility for improved performance and high-level language support; the 6809 and 6800 were software compatible in that assemblers could (and generally did) generate code which was ...
An early advertisement for the Motorola's M6800 family microcomputer system. The M6800 Microcomputer System (latter dubbed the Motorola 6800 family, M6800 family, or 68xx) [1] [2] was a series of 8-bit microprocessors and microcontrollers from Motorola that began with the 6800 CPU.
The Motorola 68000 series (also known as 680x0, m68000, m68k, or 68k) is a family of 32-bit complex instruction set computer (CISC) microprocessors. During the 1980s and early 1990s, they were popular in personal computers and workstations and were the primary competitors of Intel 's x86 microprocessors.

In 1983, OS-9/6809 was ported to Motorola 68000 assembly language and extended (called OS-9/68K); and a still later (1989) version was rewritten mostly in C for further portability. The portable version was initially called OS-9000 and was released for 80386 PC systems around 1989, then ported to PowerPC around 1995.
The 68HC12 adds to and replaces a small number of 68HC11 instructions with new forms that are closer to the 6809 processor. More significantly it changes the instruction encodings to be far more dense and adds many 6809 like indexing features, some with even more flexibility. The net result is that code sizes are typically 30% smaller. [1]
