Device Description
The control signals for the configuration memory device (nCS, RESET/OE and DCLK) interface
directly with the FPGA device control signals. All FPGA devices can control the entire configura-
tion process and retrieve data from the configuration device without requiring an external
intelligent controller.
The RESET/OE and nCS pins control the tri-state buffer on the DATA output pin and enable the
address counter. When RESET/OE is driven Low, the configuration device resets its address
counter and tri-states its DATA pin. The nCS pin also controls the output of the AT17FxxA
Series Configurator. If nCS is held High after the RESET/OE reset pulse, the counter is disabled
and the DATA output pin is tri-stated. When OE is subsequently driven High, the counter and the
DATA output pin are enabled. When RESET/OE is driven Low again, the address counter is
reset and the DATA output pin is tri-stated, regardless of the state of nCS.
When the configurator has driven out all of its data and nCASC is driven Low, the device tri-
states the DATA pin to avoid contention with other configurators. Upon power-up, the address
counter is automatically reset.
