high eciency requirements for volume production.
1.2 Main Features
• Supports Holtek 8-bit Flash MCU programming
• Uses the HOPE3000 software
• Programming les are downloaded to the programing module
• Supports programming module rmware online one-click quick update
• Compact size (136×75×23mm) for usage convenience with xture
• Supports up to 8 sites parallel programming
• 2/4/6/8 sites parallel programming available

1.4 Software Introduction
The software HOPE3000 (V3.26 and above) is used, refer to appendix HoltekEWriterUsersGuide(125).pdf
for detailed HOPE3000 usage description. After the G-ICPM08040 hardware is connected, the hardware
name and rmware version will be displayed at the lower right corner of the software interface, as shown
in Figure 4:

2.1 Online Programming Mode
In this mode, only the ICP1 unit works. Connect the programming module to a PC using a USB
cable and open the software. The ICP1-RUN LED will be illuminated indicating that it is in the
online programming mode, as shown in Figure 5. For online programming specific operations
together with the HOPE3000, refer to appendix HoltekEWriterUsersGuide(125).pdf. Note that
online programming does not support smart programming.

2.2 O󰀪ine Programming Mode
O󰀪ine Programming Data Download
Connect the programming module to a PC via a USB cable. After the module has successfully
connected, open the desired file and download it, as shown in Figure 6. Refer to appendix
HoltekEWriterUsersGuide(125).pdf for the specic software operation procedures. When the oine
data download has successfully completed, the STATUS LED will remain on.

After a 5V/3A power is connected, the STATUS LED will remain on. Press the START key to
implement programming. The programming states can be observed by the corresponding LEDs.

Programming Mode Selection
Either 2 or 4 site parallel programming can be selected using the OPTION S/W settings according
to the actual requirements, as shown in Figure 8 and Table 1. With regard to 6 or 8 site parallel
programming description, refer to 3.2 Programming Mode Selection.

3 Using the Programming Module together with the Base Board
In the offline programming mode, using the programming module together with the base board
can implement 2/4/6/8 sites parallel programming in the standard mode or 12/16 site parallel
programming in the extension mode. To implement programming module oine data download,
connect the programming module to the PC via a USB cable directly. It is not necessary to remove it
from the base board.

O󰀪ine Programming Data Download
The hardware connection is shown in Figure 9 and the specific operation steps are the same as
2.2 Oine Programming Mode – Oine Programming Data Download.

O󰀪ine Programming
After the oine programming data has been downloaded successfully, remove the USB cable from
the PC. Connect a 5V/3A power to the programming module after which then the STATUS indicator
of each programming module will be on. Press the START key to start programming after which
the programming results can be obtained by observing the LED indicator on the corresponding
programming module.

3.2 Programming Mode Selection
Standard Mode
2, 4, 6 or 8 site parallel programming can be selected by the OPTION S/W settings, as shown in
Figure 11.

Figure 11. Programming Mode Selection – Standard Mode
Extension Mode
In the oine programming mode, if the base board works together with 4 programming modules, up
to 16 Holtek 8-bit Flash MCUs can be programmed in parallel as shown in Figure 12.

4 Considerations
• Regarding the power supply (5V/3A) and the programming lines, it is strongly recommended to
use the original accessories included in the product.
• Each separate programming channel (ICPx) provides a current of only 150mA.
• When programming, the capacitor connected to the base board VDD should not exceed a value
of 220μF.
• The online programming mode does not support smart programming, namely auto programming.
As shown in Figure 13, the auto programming button is disabled with a grey colour.
