25. Output Slew Rate Control
Each ATF1500ABV macrocell contains a configuration bit for each I/O to control its output slew
rate. This allows selected data paths to operate at maximum throughput while reducing system
noise from outputs that are not speed-critical. Outputs default to slow edges, and may be individ-
ually set to fast in the design file. Output transition times for outputs configured as “slow” have a
t
SSO delay adder.
26. Security Fuse Usage
A single fuse is provided to prevent unauthorized copying of the ATF1500ABV fuse patterns.
Once programmed, fuse verify and preload are prohibited. However, the 160-bit User Signature
remains accessible.
The security fuse should be programmed last, as its effect is immediate.
