Power-up Reset
The registers in the ATF16V8Bs are designed to reset during power-up. At a point delayed
slightly from V
CC crossing VRST, all registers will be reset to the low state. As a result, the regis-
tered output state will always be high on power-up.
This feature is critical for state machine initialization. However, due to the asynchronous nature
of reset and the uncertainty of how V
CC actually rises in the system, the following conditions are
required:
1.
The V
CC rise must be monotonic,
2.
After reset occurs, all input and feedback setup times must be met before driving the
clock pin high, and
3.
The clock must remain stable during t
PR.

Preload of Registered Outputs
The ATF16V8B’s registers are provided with circuitry to allow loading of each register with either
a high or a low. This feature will simplify testing since any state can be forced into the registers
to control test sequencing. A JEDEC file with preload is generated when a source file with vec-
tors is compiled. Once downloaded, the JEDEC file preload sequence will be done automatically
by most of the approved programmers after the programming.
5.
Security Fuse Usage
A single fuse is provided to prevent unauthorized copying of the ATF16V8B fuse patterns. Once
programmed, fuse verify and preload are inhibited. However, the 64-bit User Signature remains
accessible.
The security fuse should be programmed last, as its effect is immediate.
