GENERAL DESCRIPTION

The Z86U18 USB Controller is a member of the Z8

簍

MCU

family. 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 dedi-

cated 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 tim-

ing, 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 num-

ber 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 bit-manipulation capabilities, and

easy hardware/software system expansion, along with low

cost and low power consumption, the Z86U18 meets the

needs of a variety of sophisticated applications (Figure 1:

Functional Block Diagram)

Notes

: All signals with a preceding front slash, "/", are ac-

tive Low. For example, B//W (WORD is active Low); /B/W

(BYTE is active Low, only).
