22. OTP PROGRAMMING
The GMS81516BT/24BT are OTP (One Time Program-
mable) microcontrollers. Its internal user memory is con-
structed with EPROM (Electrically Programmable Read
Only Memory).
The OTP micorcontroller is generally used for chip evalu-
ation, first production, small amount production, fast mass
production, etc.
Blank OTP’s internal EPROM is filled by 00
Note: In any case, you have to use *.OTP file, not *.HEX
file. After assemble, both OTP and HEX file are generated
by automatically. The HEX file is used during porgram em-
ulation on emulator.
22.1 How to Program
To program the OTP devices, user can use HME own pro-
grammer or third party universal programmer shown as
listed below.
HME own programmer list
Manufacturer: Hyundai MicroElectronics
Programmer: Choice-Dr Writer
The Choice-Dr Writer is single writer and physically add-
on adapter board type, it should be used with Choice-Dr
emulator. However, the Choice-Sigma is stand alone HME
universal single programmer for any HME OTP devices,
also the Choice-Gang4 can program four OTPs at once.
Ask to HME sales part which is listed on appendix of this
manual.
Third party programmer list
Manufacturer: Hi-Lo Systems
Programmer: ALL-11, ALL-07
Website : http: //www.hilosystems.com.tw
Socket adapters are supported by third party programmer’s
manufacturer. The other third party will be registered and
being under development.
Programming Procedure
1. Select device GMS81516BT or GMS81524BT.
2. Load the *.OTP file to the programmer. The file is com-
