20. OTP PROGRAMMING
GMS82512/16/24
Programming Procedure
The GMS82524T is OTP (One Time Programmable) mi-
crocontroller. Its internal user memory is constructed with
EPROM (Electrically Programmable Read Only Memo-
ry).
1. Select device GMS82524T.
2. Load the *.OTP file to the programmer. The file is com-
posed of Motorola-S1 format.
The OTP micorcontroller is generally used for chip evalu-
ation, first production, small amount production, fast mass
production, etc.
3. Set the programming address range as below table.
GMS82524T
Blank OTP’s internal EPROM is filled by 00H, not FFH.
Address
Set Value
2000H
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.

4. Mount the socket adapter on the programmer.
5. Start program/verify.
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.
20.2 Pin Function
VPP (Program Voltage)
V
PP is the input for the program voltage for programming
HME own programmer list
the EPROM.
Manufacturer: Hyundai MicroElectronics
Choice-Dr Writer
Programmer:
CE (Chip Enable)
Choice-Sigma, Choice-Gang4
CE is the input for programming and verifying internal
EPROM.
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.
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.
Ask to HME sales part which is listed on appendix of this
manual.
D0~D7 (EPROM Data Bus)
These are data bus for internal EPROM.
Third party programmer list
N.C. (No Connection)
Manufacturer: Hi-Lo Systems
ALL-11, ALL-07
Programmer:
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.
