Notes to
(1) For external flash interface support in EPC8 enhanced configuration device, contact Altera Applications.
(2) Pin A20 in EPC16 devices, pins A20 and A19 in EPC8 devices, and pins A20, A19, and A18 in EPC4 devices should be left floating. These pins
(3) In the 100-pin PQFP package, you must externally connect the following pins: C-A0 to F-A0, C-A1 to F-A1, C-A15 to F-A15, C-A16 to

In the absence of the lock bit protection feature in the EPC4, EPC8, and EPC16 devices
with Intel flash, Altera recommends four methods to protect the Intel Flash content in
EPC4, EPC8, and EPC16 devices. Any method alone is sufficient to protect the flash.
The methods are listed here in the order of descending protection level:
1. Using an RP# of less than 0.3 V on power-up and power-down for a minimum of

. Additionally, you must make the following pin connections in both 100-pin PQFP and 88-pin UFBGA packages:
1–15.
100 ns to a maximum 25 ms disables all control pins, making it impossible for a
write to occur.
