before PD High
The ATF1504AS includes an optional pin-controlled power-down feature. When this
mode is enabled, the PD pin acts as the power-down pin. When the PD pin is high, the
device supply current is reduced to less than 10 mA. During power-down, all output data
and internal logic states are latched internally and held. Therefore, all registered and
combinatorial output data remain valid. Any outputs that were in a high-Z state at the
onset will remain at high-Z. During power-down, all input signals except the power-down
pin are blocked. Input and I/O hold latches remain active to ensure that pins do not float
to indeterminate levels, further reducing system power. The power-down mode feature
is enabled in the logic design file or as a fitted or translated s/w option. Designs using
the power-down pin may not use the PD pin as a logic array input. However, all other PD
pin macrocell resources may still be used, including the buried feedback and foldback
product term array inputs.
