Description
The Atmel® AT17LVxxxA FPGA configuration EEPROMs (Configurators) provide an
easy-to-use, cost-effective configuration memory solution for FPGAs. The
AT17LVxxxA are packaged in 8-lead PDIP and 20-lead PLCC options. The
AT17LVxxxA configurator uses a simple serial-access procedure to configure one or
more FPGA devices. The user can select the polarity of the reset function by
programming four EEPROM bytes. These devices support a write protection
mechanism within its programming mode.
The AT17LVxxxA configurators can be programmed with industry-standard
programmers, the Atmel ATDH2200E Programming Kit, or the Atmel ATDH2225 ISP
Cable.

6. Cascading Serial Configuration EEPROMs
For multiple FPGAs configured as a daisy-chain, or for FPGAs requiring larger configuration memories,
cascaded configurators provide additional memory.
After the last bit from the first configurator is read, the next clock signal to the configurator asserts its nCASC
output low and disables its DATA line driver. The second configurator recognizes the low level on its nCS input
and enables its DATA output.
After configuration is complete, the address counters of all cascaded configurators are reset if the RESET/OE
on each configurator is driven to a Low level.
If the address counters are not to be reset upon completion, then the RESET/OE input can be tied to a High
level.
The AT17LV65A (NRND) does not have the nCASC feature to perform cascaded configurations.
7. AT17LVxxxA Reset Polarity
The AT17LVxxxA configurator allows the user to program the polarity of the RESET/OE pin as either
RESET/OE or RESET/OE. This feature is supported by industry-standard programmer algorithms.
8. Programming Mode
The programming mode is entered by bringing SER_EN Low. In this mode the chip can be programmed by the
2-wire serial bus. The programming is done at VCC supply only. Programming super voltages are generated
inside the chip.
9. Standby Mode
The AT17LVxxxA enters a low-power standby mode whenever nCS is asserted High. In this mode,
the configurator consumes less than 150μA of current at 3.3V. The output remains in a high-impedance state
regardless of the state of the RESET/OE input.
