Parallel Programming
27.7.1
Enter Programming Mode
The following algorithm puts the device in Parallel (High-voltage) Programming mode:
1. Set Prog_enable pins listed in
V
CC
2. Apply 4.5V - 5.5V between V
Ensure that V
3. Wait 20 µs - 60 µs, and apply 11.5V - 12.5V to RESET.
4. Keep the Prog_enable pins unchanged for at least 10µs after the High-voltage has been
applied to ensure the Prog_enable Signature has been latched.
5. Wait at least 300 µs before giving any parallel programming commands.
6. Exit Programming mode by power the device down or by bringing RESET pin to 0V.
If the rise time of the V
tive algorithm can be used.
1. Set Prog_enable pins listed in

2. Apply 4.5V - 5.5V between V
3. Monitor V
