Even before the 6809 was released, in 1976 Motorola had launched its own advanced CPU project, then known as Motorola Advanced Computer System on Silicon project, or MACSS. Although too late to be chosen for the IBM PC project, when MACSS appeared as the Motorola 68000 in 1979 it took any remaining interest in the 6809. Motorola soon announced ...

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 ...
Motorola mainly used even numbers for major revisions to the CPU core such as 68000, 68020, 68040 and 68060. The 68010 was a revised version of the 68000 with minor modifications to the core, and likewise the 68030 was a revised 68020 with some more powerful features, none of them significant enough to classify as a major upgrade to the core.
The core 6809 CPU was designed by John Kent and is currently running at 25 MHz. OS-9000/80x86 can be run on PC-type machines built around the Intel x86 CPUs. OS-9000 has also been ported to the PowerPC, MIPS, some versions of Advanced RISC Machines' ARM processor, and some of the Hitachi SH family of processors.
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 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.
BASIC09 is a structured BASIC programming language dialect developed by Microware on behalf of Motorola for the then-new Motorola 6809 CPU and released in February 1980. [1] It is primarily used with the OS-9 operating system, released in 1979. Microware also released a version for OS-9/68k on the 68000 as Microware BASIC. [2]
