10 / 31 page  Motorola Master Selection Guide Single-Chip Microcontrollers (AMCU) 2.6–10 M6800 Series Microprocessors and Peripherals These devices are a testament to the staying power of Motorola microtechnology. The original MC6800 was Introduced in 1975, and is still in demand today. Quality M6801, M6804 and M6805 systems have been performing reliably in automotive, industrial, and office equipment applications for years. Each of these devices can be combined with various peripherals to meet the requirements of a microcontroller design. Table 3.
