GMS81608T (OTP) PROGRAMMING

The GMS81608T is one-time PROM (OTP) micro-

controller with 8K bytes electrically programmable

read only memory for the GMS81604/08 system

evaluation, first production and fast mass production.

The programming to the OTP device, user can have

two way. One is using the universal programmer which

is support LGS microcontrollers, other is using the

general EPROM programmer.

1. Using the Universal programmer

Third party universal programmer support to program

the GMS81608T 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 give 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.

Socket Adapter

Package Type

OA816A-40SD

40 pin DIP

OA816A-42SD

42 pin SDIP

OA816A-42PL

44 pin PLCC

W ith these socket adapters, the GMS81608T can easy

be programming and verifying using 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-DrTM or CHOICE-JrTM) 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

Set Value

Buffer start address

6000H

Buffer end address

7FFFH

Device start address

6000H

5. Mount the socket adapter with the GMS81608T on

the PROM programmer.

6. Start the PROM programmer to programming/

verifying.
