The Improved Quick Pulse algorithm is based on the Quick Pulse algorithm and
decreases the number of pulses applied during byte programming from 25 to 1.
To program the TS87C52X2 the following sequence must be exercised:
•
•
•
•
•
•
Repeat step 2 through 6 changing the address and data for the entire array or until the
end of the object file is reached (See Figure 12.).
Code array verify must 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 TS87C52X2.
P 2.7 is used to enable data output.
To verify the TS87C52X2 code the following sequence must be exercised:
•
•
•
Repeat step 2 through 3 changing the address for the entire array verification (See Fig-
ure 12.)
The encryption array cannot be directly verified. Verification of the encryption array is
done by observing that the code array is well encrypted.
Step 1: Activate the combination of control signals.
Step 2: Input the valid address on the address lines.
Step 3: Input the appropriate data on the data lines.
Step 4: Raise EA/VPP from VCC to VPP (typical 12.75V).
Step 5: Pulse ALE/PROG once.
Step 6: Lower EA/VPP from VPP to VCC
Step 1: Activate the combination of program and control signals.
Step 2: Input the valid address on the address lines.
Step 3: Read data on the data lines.
