8. OTP PROGRAMMING
8.1 HMS97C8032 OTP Programming
Blank Check
Since the initial values of program memory and encryption ta-
ble memory are all 0s, the HMS97C8032 will return FFh if a
blank program memory byte is read. We recommend the follow-
ing blank check method for a not programmed HMS97C8032
chip.
1.Set every ROM writer program encryption array(00~3h) value
to 00h.
2.Read a program memory byte from a HMS97C8032.
3.If the read value in step 2 is FFh, the program memory byte is
blank.
Program writing
To burn program file, refer following procedure.
Make program OTP file.
Check blank.
Burn program OTP file (Set chip target address
0000h ~ 7FFFh)
Some ROM writers skip FFh data writing to program memory or
encryption array, assuming that the initial value is FFh. But for
the HMS97C8032 device , the initial value of program memory
byte or encryption array is 00h, so you should not skip FFh data
write to program memory or encryption array.
