20. OTP PROGRAMMING
The GMS82524T is OTP (One Time Programmable) mi-
crocontroller. Its internal user memory is constructed with
EPROM (Electrically Programmable Read Only Memo-
ry).
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_H, not FF_H.
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.
20.1 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
Choice-Sigma, Choice-Gang4
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 GMS82524T.
2. Load the *.OTP file to the programmer. The file is com-
posed of Motorola-S1 format.
3. Set the programming address range as below table.

4. Mount the socket adapter on the programmer.
5. Start program/verify.
20.2 Pin Function
V_PP (Program Voltage)
V_PP is the input for the program voltage for programming
the EPROM.
CE (Chip Enable)
CE is the input for programming and verifying internal
EPROM.
OE (Output Enable)
OE is the input of data output control signal for verify.
A0~A15 (Address Bus)
A0~A15 are address input pins for internal EPROM.
D0~D7 (EPROM Data Bus)
These are data bus for internal EPROM.
