Description The AT17FxxA Series of In-System Programmable Configuration PROMs (Configurators) provide an easy-to-use, cost-effective configuration memory for Field Programmable Gate Arrays. The AT17FxxA Series device is packaged in the 44-lead PLCC see Table 1-1. The AT17FxxA Series Configurator uses a simple serial-access procedure to configure one or more FPGA devices. The AT17FxxA Series Configurators can be programmed with industry-standard programmers, Atmel’s ATDH2200E Programming Kit or Atmel’s ATDH2225 ISP Cable. Table 1-1.

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 configuration 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 subsequen.
