The control signals for the configuration EEPROM (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 EEPROM without requiring an external
controller.
The configuration EEPROM’s RESET/OE and nCS pins control the tri-state buffer on the DATA
output pin and enable the address counter and the oscillator. When RESET/OE is driven Low,
the configuration EEPROM resets its address counter and tri-states its DATA pin. The nCS pin
also controls the output of the AT17A series configurator. If nCS is held High after the
RESET/OE pulse, the counter is disabled and the DATA output pin is tri-stated. When nCS is
driven subsequently Low, 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, regard-
less of the state of the 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.
This is the default setting for the device. Since almost all FPGAs use RESET Low and OE High,
this document will describe RESET/OE.
