GMS81C7208/7216
24. DEVELOPMENT TOOLS
24.1 OTP Programming
The GMS87C7216 is OTP (One Time Programmable) type mi-
crocontrollers. Its internal user memory is constructed with
EPROM (Electrically programmable read only memory).
The OTP microcontroller is generally used for chip evaluation,
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 the *.OTP file for pro-
gramming, not the *.HEX file. After assemble the source
program, both OTP and HEX file are generated by automat-
ically. The HEX file is used during program emulation on
the emulator.

How to Program
To program the OTP devices, user should use MagnaChip own
programmer. Ask to MagnaChip sales part for purchasing or
more detail.
Programmer: CHOICE-SIGMA (Single type)
PGM-Plus (Single type)
StandAlone-GANG4 (4-gang type)
Socket adapter:87C70XX-64SD (for 64SDIP)
87C70XX-64QF (for 64MQFP)
87C70XX-64LQ (for 64LQFP)
The CHOICE-SIGMA is a MagnaChip universal single program-
mer for all of MagnaChip OTP devices, also the StandAlone-
GANG4 can program four OTPs at once.
Programming Procedure
1. Select device GMS87C7216 as you want.
2. Load the *.OTP file from the PC to programmer. The
file is composed of Motorola-S1 format.
3. Set the programming address range as below table.
4. Mount the socket adapter on the programmer.
5. Set the configuration bytes as your needs.
6. Start program/verify.
Select the Options for Program Lock and RC
Oscillation
Except the user program memory C000_H~FFFF_H, there is config-
uration byte (address 707F_H) for the selection of program lock
and RC oscillation. The configuration byte of OTP is shown as
Figure 24-1. It could be served when user use the OTP program-
