(Second Edition)

Introduction

The Holtek HandyWriter was specifically developed to program the range

of Holtek OTP microcontroller devices allowing users to easily and effi-

ciently burn their programming code into the OTP devices. The advan-

tages of this writer include its small and easy to manage size, ease of

installation and easy to use special features. The structure of the writer in-

cludes the following components and is shown in Figure 1 below:

·Single 40 pin DIP TEXTOOL

·Single 25 pin printer port D-type female connector

·Single 96 pin VME connector

To use the HandyWriter requires the following:

·16V power adapter with minimum current rating of 500mA. For best

purposes please use the adapter included with the HandyWriter carton.

·IBM386 compatible or higher spec. PC

·Win95/98/NT Windows operating system

·HT-IDE2000 microcontroller development system

·If the writer is directly connected to the PC, the HT-ICE is not required.

Installation

·To directly connect to a PC, use the printer cable to connect from the

HandyWriter¢s 25 pin D-type connector to the printer port of the PC as

shown in Figure 2. To connect via the HT-ICE, first connect the

HandyWriter to the VME 96 pin socket CN1 on the HT-ICE then con-

nect the HT-ICE to the PC¢s printer port using the printer cable as

shown in Figure 3.

·Install the HT-IDE2000 system software, to do so please consult the

Programming an OTP chip with the HandyWriter

èRun the HT-HandyWriter system software

Run the HT-HandyWriter system software under the HT-IDE2000 icon in

the main Windows programs menu as shown in the Figure 4 below:

èLPT ¾Setup the Printer Port

After running the HandyWriter program, a window as shown in Figure 5

will be shown, however it is first necessary to setup the correct printer port.

By selecting ²LPT²command, a sub menu as shown in Figure 6 will be dis-

played. From here LPT1, LPT2 or LPT3 can be chosen. If the OTP

HandyWriter is connected to the HT-ICE, then select the printer port to

which the HT-ICE is connected. For example if the HT-ICE is connected to

LPT1 then select LPT1 from Figure 6. If the OTP HandyWriter is directly

connected to the PC printer port then choose the relevant printer port in

the same way.

è!Body ¾Select the OTP Body Type

By clicking on ²!Body², [Set Body] dialog will be shown as Figure 7. If there

is no IC type identifier stored in the OTP chip, all the read/write operations

will be completed according to the chip type that selected by users.

è!Option ¾Check the IC Option

By clicking on ²!Option², a pop-up dialog, as shown in Figure 8, will be dis-

played. It will illustrate the option that comes from opened file or OTP chip

content.

èHT-HandyWriter Programming Functions

Figure 5 shows the provided HandyWriter functions, the details of which is

shown below:

·Open

This opens a file with the .OTP suffix, which will load the program con-

tents into the PC ram memory. This data will be accessed when program-

ming the relevant OTP device. After selecting ²Open², the file dialogue

box will be displayed from which the correct folder and file name can be

chosen. The file content will be displayed in the message window after be-

ing opened, and the checksum of the opened file will be shown under-

neath the ²Read²button.

·Program

This instruction encompasses two functions. The first is to place the pro-

gram data in the PC ram memory into the OTP device, the second is a

verification check to verify that the actual data burned into the OTP de-

vice is the same as that in the PC ram memory data. After verification

the result of this process will be shown on the HandyWriter display.

·Verify

The contents of the presently loaded OTP device will be read and checked

that it is the same as the data loaded into the PC ram memory, the re-

sults of which will be displayed on the HandyWriter display.

Figure 8

·Blank Check

Check that the presently loaded OTP device has not previously been

written to. The results of this check will be displayed on the HandyWriter

display. If the device is not empty, the memory area that has been writ-

ten to will also be shown on the display.

·Lock

This instruction will implement the protect function in the OTP device

preventing the contents of this IC from being read. After programming

an OTP device, this instruction can then be used to protect the contents.

·Auto

This instruction will execute in order the three instructions Blank

Check, Program and Verify. If any of the instructions do not execute cor-

rectly, the process will be halted and the following instruction not exe-

cuted. There is also a lock function, which can be selected to prevent the

data from being read out after programming. This lock function should

first be selected before the Auto button pressed.

·Read

This instruction will read out the contents of the OTP device presently

loaded into the HandyWriter and store them in the PC ram memory. This

instruction will also cause the file checksum to be displayed underneath

the ²Read²button. If required, this data can also be stored in a file with

the .OTP file suffix.

·Chip Info

This instruction will read power-on ID, software ID, ROM size, option

size from IC and display ²Get info from chip²message to inform users the

listed information comes from IC interior. If there is no such information

inside IC, the specification defined by ²!Body²command will be shown. It

will display ²Get info from ini²to inform users that above information co-

mes from system setting.

System Messages

èHandyWriter Connect to LPT1.

OTP HandyWriter already connected to LPT1.

èCannot connect to ICE

Connection problems between the HandyWriter, the HT-ICE and the

printer port.

èInvalid EV Chip!

The HandyWriter is unable to support the EV chip in the HT-ICE. The

HT-ICE must be changed for correct operation to take place.

èConnect to HandyWriter through ICE

The OTP HandyWriter is successfully connected via the HT-ICE.

èCannot find HandyWriter, please connect it to ICE

Or this HandyWriter is an old version

The HT-ICE is already connected to the printer port, but the HandyWriter

is not connected to the HT-ICE. It may also be that an old version of the

HandyWriter is being used (THANDYOTP-A) so the system is unable to

detect a good connection. If the former case, please connect the

HandyWriter directly to the ICE.

èFile PID: ADh, OID: 50h

The opened files recorded power-on ID is ADh, the software ID is 50h.

èInvalid OTP file format

The opened file format is incorrect.

èThe chip PID: ADh, OID: 50h doesn't match with the file PID: ADh, OID:

51h

Are you sure to continue?

The type of OTP chip and the chip supported by the opened file does not

match.

èChip ROM size: 0400h, File ROM size: 0800h. System will set ROM size as

0400h.

Are you sure to continue?

The OTP chip has 400h of writable space, the file content is 800h, so the

HandyWriter can only write 400h of data into the contents of the OTP chip.

HandyWriter User¢s Guide

èAddr: xxxxh, Data: yyyyh, Rdata: zzzzh

Program/Option Verify Failed!

Errors exist in either the program or option verification information. The

reason is because the data at the address xxxxh in the OTP chip is not the

same as the data yyyyh in the PC ram memory.

èAddr: xxxxh, Data: zzzzh

Not Blank!

The OTP chip is not blank as the address xxxxh contains the data zzzzh, in-

hibiting the implementation of further instructions.

èChip mismatched!

The OTP chip presently in the HandyWriter and the OTP chip mentioned

in the .OTP file do not match, inhibiting the implementation of further in-

structions.

èChip is locked!

The OTP chip presently in the HandyWriter is locked, inhibiting the imple-

mentation of further instructions.

èNo data to verify/program!

Before executing the Verify or Program instruction, the .OTP file must be

loaded using the ²Open²function in the HandyWriter system software.
