OTP PROGRAMMING
The GMS81504T is one-time PROM (OTP) micro-
controller with 4K bytes electrically programmable
read only memory for the GMS81504 system evalu-
ation, first production and fast mass production.
To programming the OTP device, user can have two
way. One is using the universal programmer which is
support HME microcontrollers, other is using the gen-
eral EPROM programmer.
1. Using the Universal programmer
Third party universal programmer are shown as below.
Manufacturer: Advantech
Web site: http://www.aec.com.tw
Programmer: LabTool-48
Manufacturer: Hi-Lo systems
Web site: http://www.hilosystems.com.tw
Programmer: ALL-11, GANG-08
Socket adapters are supported from third party pro-
grammer manufacturer.
2. Using the general EPROM(27C256)
programmer
When user use general EPROM programmer, socket
adaper is essencially necessary. It convert pin to fit the
pin of general 27C256 EPROM.
Socket Adapter: OA815A-30SD (30SDIP)
In assembler and file type, two files are generated after
compiled. One is "*.HEX", another is "*.OTP". The
"*.HEX" file is used for emulation in circuit emulator
CHOICE-Jr^TM and "*.OTP" file is used for program-
ming to OTP device.
Programming Procedure
1. Select the EPROM device and manufacturer on
EPROM programmer (Intel 27C256)
2. Select the programming algorithm as a Intelligent
mode (apply 1ms writing pulse).
3. Load the file (*.OTP) to the programmer.
4. Set the programming address range as below table.
Address
Buffer start address
Buffer end address
Device start address
Set Value
7000H
7FFFH
7000H
5. Mount the socket adapter with the OTP device onto
the PROM programmer.
6. Start the PROM programmer to programming/
verifying.
