• Configuration data storage for Xilinx XC3000, XC4000, XC5200, Spartan, and Virtex FPGAs

Procurement Notes

Verify that the specific part number corresponds to the LV (Low Voltage) variant operating on the 4.75V to 5.25V range, distinct from standard V versions. Confirm the package type is the 20-lead PLCC (QCCJ) as indicated by the suffix JC. Ensure compliance with RoHS requirements if applicable, noting that older Atmel documentation may list non-compliance for certain batches. Cross-reference the manufacturer designation between Atmel and Microchip to ensure accurate sourcing.

Selection Notes

Select this component when a 2M-bit serial configuration memory is required for SRAM-based FPGAs. The AT17LV002-10JC is suitable for designs requiring 5V operation with low power consumption. Consider the 20-lead PLCC package constraints for PCB layout. Verify compatibility with the target FPGA family, such as Xilinx or Altera, as the device supports multiple vendor configurations. Ensure the system design accommodates the two-wire bus interface for in-system programming.

Part Context

The AT17LV002-10JC belongs to the AT17 series of EE Programmable Serial Memories. This family includes various densities ranging from 65,536 to 4,194,304 bits. These devices are specifically engineered to store configuration data for Field Programmable Gate Arrays. The series offers flexibility through different package options including LAP, PLCC, and TQFP, ensuring pin compatibility across the product family for design scalability.

Replacement Considerations

The AT17C002-10JC is a related variant within the same product family, offering similar functionality but potentially differing in voltage specifications or manufacturing revisions. Verify electrical characteristics and package compatibility before substitution.
