Introduction
This User Manual describes how to setup and use Zilog’s Z8 Encore!® Smart Cable with
Z8 Encore! development kit. This can also be used for Z8 Encore! XP®development kit.
The Z8 Encore! Smart Cable converts the RS-232 signals into the 3.3 V bidirectional
open-drain signals required to communicate using the DBG pin to the Zilog on-chip
debugger of the Z8 Encore!. The Smart Cable features a 9-pin DB serial connector on one
end and a box with a 6-pin DBG Interface Connector on the other end.
The development kit includes the following (see Figure 1):

Voltage and Current Requirements
The voltage and current requirements of the Z8 Encore!®Serial Smart Cable include:
• System Clock: 153.6 kHz minimum, 20 MHz maximum
• Power Supply: 3.0 V minimum, 3.6 V maximum
• Current: 35 mA at 3.3 V
Connecting the Z8 Encore! Smart Cable to Your Computer
Connect the Z8 Encore! Smart Cable to a COM port on your computer using the 9-pin DB
serial connector (see Figure 2).

Connecting the Smart Cable to Your Development Board
To use the Z8 Encore! Smart Cable, connect the application board to the Smart Cable 6-pin
DBG connector. Ensure that Pin 1 of the application lines up with Pin 1 of the DBG
connector, indicated by the horizontal/vertical groove over the Pin 1 placement (see
Figure 3 on page 3). For more information on interfacing the Smart Cable to your target
board, refer to Z8 Encore!®Design for Debug Technical Note (TN0036).

The power to your design/application board must be turned OFF when
connecting or disconnecting the Smart Cable.
The Smart Cable receives power from the target design/application board.
Figure 3. DBG Interface Connector Pin 1 Location
Consider the following points when connecting the Smart Cable to your development
board:
• The DBG interface connector requires the VDD, VSS, and the DBG signals from the
Z8 Encore! on your design/application board.
• The minimum signal connections required to connect the Z8 Encore! to the Smart
Cable are the AVDD, VDD, AVSS, VSS, and the DBG pin signals.
•TheAV
DD must be externally connected to the VDD. The AVSS must also be
externally connected to the VSS.
• The Z8 Encore! must be clocked to generate the DBG timing signals. For the
recommended crystal oscillator circuit, refer to Product Specification of target MCU.
You must enter the crystal frequency running the Z8 Encore! device when cre-
ating a new project in ZDS II.
Follow the steps below to provide the crystal frequency:
1. Select Settings from the Project menu.
