6. GMS81516AT (OTP) PROGRAMMING
The GMS81516AT is one-time PROM (OTP) micro-
controller with 16K bytes electrically programmable
read only memory for the GMS81508/16 system
evaluation, 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 support to program
the GMS81516AT microcontrollers and lists 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 by third party program-
mer manufacturer.
2. Using the general EPROM(27C256)
programmer
The programming algorithm is simmilar with the stan-
dart EPROM 27C256. It gives some convience that user
can use standard EPROM programmer. Make sure
that 1ms programming pulse must be used, it gener-
ally called "Intelligent Mode". Do not use 100us
programming pulse mode, "Quick Pulse Mode".
When user use general EPROM programmer, socket
adaper is essencially required. It convert pin to fit the
pin of general 27C256 EPROM.
Three type socket adapters are provided according to
package variation as below table.
With these socket adapters, the GMS81516AT can
easy be programming and verifying using Intel
27C256 EPROM mode on general-purpose PROM
programmer.
In assembler and file type, two files are generated after
compiling. One is "*.HEX", another is "*.OTP". The
"*.HEX" file is used for emulation in circuit emulator
(CHOICE-Dr^TM or CHOICE-Jr^TM) and "*.OTP" file
is used for programming to the OTP device.
Programming Procedure
1. Select the EPROM device and manufacturer on
EPROM programmer (Intel 27C256).
2. Select the programming algorithm as an Intelligent
mode (apply 1ms writing pulse), not a Quick pulse
mode.
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
4000H
7FFFH
4000H
5. Mount the socket adapter with the GMS81516AT on
the PROM programmer.
6. Start the PROM programmer to programming/
verifying.
