22. OTP PROGRAMMING
The GMS81516BT/24BT and GMS82524T are OTP (One
Time Programmable) microcontrollers. Its internal user
memory is constructed with EPROM (Electrically Pro-
grammable 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
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.
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.

22.1 How to Program
To program the OTP devices, user can use Hynix own pro-
grammer or third party universal programmer shown as
listed below.
Hynix own programmer list
Manufacturer:
Hynix Semiconductor Inc.
Programmer:
Choice-Sigma,
Stand-alone Gang4
Buffer end address
Device start address
4. Mount the socket adapter on the programmer.
5. Start program/verify.
22.2 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.
O0~O7 (EPROM Data Bus)
These are data bus for internal EPROM.
Choice-Sigma is a Hynix universal single programmer for
any Hynix OTP devices, and the Stand-alone Gang4 can
program four OTPs at once.
Ask to Hynix sales part which is listed on appendix of this
manual for purchasing or more detail.
Third party programmer list
Manufacturer: Hi-Lo Systems
Programmer:
ALL-11

ALL-07
: Even though Hilo System does not support
ALL07 any longer, User can get the specific program algo-
rithm and socket adapter for ALL-07 from Hynix sales
part. ( File name : AMPU7.EXE )
Programming Procedure
1. Select device GMS81516BT or GMS81524BT or
GMS82524T as you want.
