Description
V750 Cross-programming. JEDEC file compatible with standard V750 JEDEC
file (total fuses in JEDEC file = 14394). The Programmer will automatically
program “0”s into the User Rrow (UES), and disable the Pin-keeper features. The
Fuse Checksum will be the same as the old ATV750/L file. This device type is
recommended for customers that are directly migrating from an ATV750/L device
to an ATF750C/CL device.

V750B Cross-programming. JEDEC file compatible with standard V750B
JEDEC file (total fuses in JEDEC file = 14435). The Programmer will
automatically program “0”s into the User Row (UES), and disable the Pin-keeper
feature. The Fuse Checksum will be the same as the old ATV750B/BL file. This
device type is recommended for customers that are directly migrating from an
ATV750B/BL device to an ATF750C/CL device.
ATF750C (V750B)
ATF750C
Programming of User Row (UES) bits supported and Pin-keeper bit is user-
programmable. (Total fuses in JEDEC file = 14504). This is the default device
type and is recommended for users that have re-compiled their source design
files to specifically target the ATF750C device.
Note:
1. The ATF750C has 14,504 JEDEC fuses.
28. Security Fuse Usage
A single fuse is provided to prevent unauthorized copying of the ATF750C(L) fuse patterns.
Once the security fuse is programmed, all fuses will appear programmed during verify.
The security fuse should be programmed last, as its effect is immediate.
