PROGRAMMING ALGORITHM
Refer to Table 3 and Figures 11 and 12 for address,
data, and control signals set up. To program the
87C51FA/FB/FC the following sequence must be
exercised.
1. Input the valid address on the address lines.
2. Input the appropriate data byte on the data lines.
3. Activate the correct combination of control sig-
nals.
4. Raise EA/V PP from VCC to 12.75V g0.25V.
5. Pulse ALE/PROG 5 times for the EPROM array,
and 25 times for the encryption table and the lock
bits.
Repeat 1 through 5 changing the address and data
for the entire array or until the end of the object file is
reached.
PROGRAM VERIFY
Program verify may be done after each byte or block
of bytes is programmed. In either case a complete
verify of the programmed array will ensure reliable
programming of the 87C51FA/FB/FC.
The lock bits cannot be directly verified. Verification
of the lock bits is done by observing that their fea-
tures are enabled. Refer to the EPROM Program
Lock section in this data sheet.
