1. e-Link Introduction
The e-Link is Holtek’s third generation simulator/programmer for use with Holtek Flash MCU
devices. It includes both OCDS (On-Chip Debug Support) and ICP (In-Circuit Programming)
functions.
2. e-Link Appearance and ICP Functions
2.1 e-Link Appearance

3. e-Link ICP Usage Flow Description
3.1 HOPE3000 for e-Link Software Update
LogontotheHoltekofcialwebsite(http://www.holtek.com.cn/China/tech/tool/Mainpage1.htm) to
download and install the latest HOPE3000 for use with the e-Link.
3.2 Programming Function
The e-Link should be updated to be in the e-Link ICP mode by using the HOPE3000 for e-Link
software.
3.2.1 Holtek 8-bit Flash MCU
The programming pins are shown as follows:
Table 1. 5-wire Connection Figure 5
Table 2. 4-wire Connection Figure 6
Note:Whentheadaptorleadisused,a0.1μFcapacitorshouldbeconnectedbetweenVDDand
GND.
BeforeICPoperation,rstclick“File”→“Open”toopentheMTPletobeprogrammed,then
correctly connect the target Holtek 8-bit Flash MCU.
The initialisation interface of the HOPE3000 for e-Link software is as follows.

【Upload】
• Upload
Theuploadoptionincludessixcommands,“Program”,“EEData”,“ALL”,“VerifyProgram”,
“VerifyEEData”and“VerifyAll”.
• Select“Program”:OnlyreadtheProgramMemorydata.
• Select“EEData”:OnlyreadtheEEPROMMemorydata.
• Select“ALL”:TheProgramMemoryandEEPROMMemorydatawillbothberead.
• Select“VerifyProgram”:OnlyverifytheProgramMemorydata.
• Select“VerifyEEData”:OnlyverifytheEEPROMMemorydata.
• Select“VerifyAll”:TheProgramMemoryandEEPROMMemorydatawillbothbeveried.
Note: The read data will be shown in the corresponding window. If the data is to be stored then click
the“Save”buttonunderthe“File”option.

【Download】
• Download
Thedownloadoptionincludeseightcommands,“Program”,“EEData”,“ALL”,“AutoVerify”,
“EraseProgram”,“EraseEEData”,“EraseAll”and“LockChip”.
• Download Steps:
1.Click“File/Open”toopenthecorresponding.MTPle.
2.Select“Program”:TheProgramMemorydatawillbedownloadedtothetargetMCU.
Select“EEData”:TheEEPROMMemorydatawillbedownloadedtothetargetMCU.
Select“ALL”:TheProgramMemoryandEEPROMMemorydatawillbothbedownloadedto
the target MCU.
3.Afterthedownloadcommandisexecuted,iftheMCUprogramsarerequiredtobeexecuted,
clickthe“PowerOn”functionunderthe“Tools”option,orselectthe“AutoPowerOn”
functionunderthe“Tools”optionbeforethedownloadcommandisexecuted.
• AutoVerify
Whenthisoptionisselected,ifthedownload“Program”,“EEData”and“ALL”commandsare
executed, the system will automatically verify data for the current executing command.
• Erase
IftheMCUprogramsordataarerequiredtobeupdated,the“EraseProgram”or“EraseEEData”
commandcanbeexecuteddirectlyasneeded.HoweveriftheMCUislocked,the“EraseAll”
command should be executed.
• Lock Chip
Afterthedownloadcommandisperformed,iftheMCUdataisrequiredtobeprotected,the“Lock
Chip”functionunderthe“Download”optioncanbeexecuted.Thiswillensurethatthedata
written to the MCU cannot be read.
【Tools】
• Tools
This option is mainly to implement power supply control and reset function selection for the
target IC.
• ViewOption
If this function is selected, the options setup in the HOPE3000 for e-Link will pop up.
• Reset
If this command is executed, the MCU will be forced to return to the program initial state and
rerun.
• Power On
If the power has been successfully connected, then after the command is executed, the program
downloadedtotheMCUwillrun.Thevoltageiseither3.3Vor5V,whichuserscanchoose
according to their needs.
Note: If users want to use the ICP mode, the Target Board can be supplied directly with either a
3.3Vor5Vpowersupply.Themaximumcurrentis300mAwhichshouldmeettheneedsof
mosttargetboards.Ifhighercurrentsarerequiredthenanexternalpowersupplyshouldbe
connected.
• Power Off
AfterthiscommandisexecutedthetargetICwillhavenopowerandtheprogramswillnotrun.
• AutoPowerOn
Function:Afterthe“Download”,“Upload”andothercommandsareexecuted,thesystemwill
supply power to the devices automatically.
