GMS84512T/GMS84524T EPROM PROGRAMMING

4.2 GMS84524T Programming

The Font address ranges are from 0000H to 1FF1H and PGM addres ranges are from 2000H to 7FFFH in OTP file.

Firstly, the programmer program the Font data into the GMS84524T OTP device ( from 2000H to 3FF1H ), and

then program the PGM data into the GMS84524T OTP device ( from A000H to FFFFH ).

When the programmer write the Font data 0000H to 1FF1H, consequently, the data actually will be written into

address 2000H to 3FF1Hof the GMS84524T OTP device. And PGM data 2000H to 7FFFH, consequently, the

data actually will be written into address A000H to FFFFHof the GMS84524T OTP device.

1. The data format to be programmed is made up of Motorola S1 format.

Ex) "Motorola S1" format;

FONT

0000H ~ 1FF1H

PGM

2000H ~ 7FFFH

2. Down load above data into programmer from PC.

3. Programming the data from address 0000H to 1FF1H and 2000H to 7FFFH into OTP MCU, the data must be

turned over respectively, and then record the data.

Ex) 00âFF, 76â89, FFâ00 etc.

4. Of course, the check sum is result of the sum of whole data from address 0000H to 7FFFH in the file (not reverse

data of OTP MCU).

Caution : In the OTP file, data FFH, BFH are written in 1FF0H and 1FF1H respectively. However, the

OTP chip was written already 49H, 63H in that addresses. Therefore, that addresses should be

skipped in programming or blank check. And should be treated FFH, BFH in checksum

calculation ( READ or VERIFY).

On the checksum calculation, not used area data should be regarded as FFH in OTP file.

When GMS84524T shipped, the blank data of GMS84524T is initially 00H (not FFH).
