The device is housed in a 40-pin DIP package, and is manufactured in NMOS technology.
The Z08617 microcontroller offers fast execution, efficient use of memory, sophisticated interrupt, input/output bitmanipulation capabilities, and easy hardware/software system expansion along with low cost and low power consumption.
The Z08617 architecture is characterized by a flexible I/O scheme, an efficient register, I/O, and a number of ancillary features that are useful in many industrial and advanced scientific applications.
For applications which demand powerful I/O capabilities, the Z08617 provides 32 pins dedicated to input and output.
These lines are grouped into four ports, each port consists of 8 lines, and are configurable under software control to provide timing, status signals, and serial or parallel I/O ports.
The Z08617 offers low EMI emission which is achieved by means of several modifications in the output drivers and clock circuitry of the device.
There are two basic address spaces which are available to support this wide range of configurations: Program Memory and 124 General-Purpose Registers.
The Z08617 offers two on-chip counter/timers with a large number of user-selectable modes.
This unburdens the program from coping with real-time problems such as c...
