Two new additions to the M6805 family of microcomputers include features particularly suited to applications in an automobile environment. The MC6805S2 version has a powerful timer architecture for use with electronics ignition systems; while the MC6805K2 on the other hand includes a long awaited EEPROM memory capability on chip. Both devices also feature Serial Peripheral Interface (SPI), allowing fast data transfer rates between processors within the same module or between the MCU and display driver circuits, A/D or D/A converters. The small number of lines needed by the SPI to interface the MCU to the external peripheral parts saves pins on the IC's and is also a cost effective way of networking several devices on the same module with a minimum of software overhead. This paper highlights the timer subsystem of the MC6805S2 as its key feature, and on-board EEPROM memory as a distinctive feature of the MC6805K2. Since the SPI is included in both devices, the MC6805S2 and MC6805K2, it will be discussed separately from the individual MCU descriptions.
