Description
The AT17LV series FPGA Configuration EEPROMs (Configurators) provide an easy-
to-use, cost-effective configuration memory for Field Programmable Gate Arrays. The
AT17LV series device is packaged in the 8-lead LAP, 8-lead PDIP, 8-lead SOIC, 20-
lead PLCC, 20-lead SOIC, 44-lead PLCC and 44-lead TQFP, see Table 1. The
AT17LV series Configurators uses a simple serial-access procedure to configure one
or more FPGA devices. The user can select the polarity of the reset function by pro-
gramming four EEPROM bytes. These devices also support a write-protection
mechanism within its programming mode.
The AT17LV series configurators can be programmed with industry-standard program-
mers, Atmel's ATDH2200E Programming Kit or Atmel's ATDH2225 ISP Cable.
Notes:
1. The 8-lead LAP package has the same footprint as the 8-lead SOIC. Since an 8-
lead SOIC package is not available for the AT17LV512/010/002 devices, it is possi-
ble to use an 8-lead LAP package instead.
2. The pinout for the AT17LV65/128/256 devices is not pin-for-pin compatible with the
AT17LV512/010/002 devices.
3. Refer to the AT17Fxxx datasheet, available on the Atmel web site.

Device Description
The control signals for the configuration EEPROM (CE, RESET/OE and CCLK) inter-
face directly with the FPGA device control signals. All FPGA devices can control the
entire configuration process 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.
