These Notes are beside the Eprom selections on the Previous pages:
1– Use the Model 210 adapter with this 40 pin Eprom.
2– Use the Model 481 adapter with this 40 pin MPU.
3– Use the Model 514 adapter with this part and the Model 9000
Versions 5.31 and later. See Note 11 for 5.30 and earlier.
0000–0FFFH Code area (87C51– can also use 511 Rev D)
0000–1FFFH Code Area (87C51FA or 8752AH, 514 only)
0000–3FFFH Code Area (87C51FB, 514 only.)
0000–7FFFH Code Area (87C51FC, 514 only.)
8030H Signature byte. Manufacturer
8031H Signature byte. Part type
8800–881FH Encryption data. Key bytes go here.
Lock bit 3. NOT SUPPORTED
C000H Lock bit 2. Program FFH here for Lock 2.
CC00H Lock bit 1. Program FFH here for Lock 1.
It’s not possible to read the encryption table. You can verify it by
reading the programmed code and massage it with your original
code that you programmed the part with. If Lock bit 2 is set, you
will not be able to read or program the part at all, until you erase
it. If Lock bit 1 is set, then you can still read the part, byt you can
not program it any more until you erase it.
If you’re using a model 511 adapter (to program 87C51— not FA
or FB versions) purchased before July of 1986, make sure that it is
modified to be a REV–D for use with the Model 9000. If it is not
modified you will not be able to program the encryption or lock
bits. The modification does not affect the operation of the 511 with
other GTEK programmers. You can use a 514 (any revision)
adapter in place of a 511 adapter.
4– Pin 1 on this part should be isolated from the programmer pin 1.
Use a wire wrap socket with pin 1 cut off the socket so it can not
reach the programmer’s socket.
5– This Fujitsu 12.5 volt algorithm selection (Quick Pro) is different
from the Intel selection by the use of the –CE pin.
6– Use Model 110 adapter to program this 32 pin standard JEDEC
eprom.
