Device Description The control signals for the configuration EEPROM (CE, RESET/OE and CCLK) interface directly with the FPGA device control signals. All FPGA devices can control the entire configuration pro- cess and retrieve data from the configuration EEPROM without requiring an external intelligent controller. The configuration EEPROM RESET/OE and CE pins control the tri-state buffer on the DATA output pin and enable the address counter. When RESET/OE is driven High, the configuration EEPROM resets its address counter and tri-states its DATA pin. The CE pin also controls the output of the AT17LV series configurator. If CE 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 Low, the counter and the DATA output pin are enabled. When RESET/OE is driven High again, the address counter is reset and the DATA output pin is tri-stated, regardless of the state of CE. When the configurator has driven out all of its data and CEO 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. Note: 1. The CEO feature is not available on the AT17LV65 device. 4.
