The Z86U18 is characterized by a flexible I/O scheme, an efficient register architecture, and a number of ancillary features.
It contains a dedicated USB interface (transceiver and SIE).
For applications demanding powerful I/O capabilities, the Z86U18 (40- and 44-pin versions) provides 32 pins dedicated to application input and output.
These lines are grouped into four ports, each port consists of eight lines and are configurable under software control to provide timing, status signals, and serial or parallel I/O ports.
It also has 2 pins to connect directly to the USB cable.
To unburden the system from coping with real-time tasks, such as counting/timing and I/O data communications, the Z86U18 offers an on-chip counter/timer with a large number of user-selectable modes.
The Z86U18 achieves low EMI by means of several circuit implementations in the output drivers and clock circuitry of the device.
With fast execution, efficient use of memory, sophisticated interrupt, input/output b...
