XC17128ELPC20I

Configuration PROMs For FPGAs Overview

The AMD XC17128ELPC20I is a high-density, non-volatile FPGA configuration PROM designed for programming Xilinx Spartan-3 and Spartan-3A field-programmable gate arrays. It utilizes a 20-pin PLCC package and operates within a supply voltage range of 3V to 3.6V. The device provides 128 Mbit (16 MB) of storage capacity, enabling the secure retention of complex bitstream data without power. It supports standard SPI serial communication protocols for reliable data transfer during configuration cycles.

Configuration PROMs For FPGAs Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature rating compliance before procurement. Confirm that the target FPGA design matches the 128 Mbit density requirements. Ensure the PCB layout accommodates the 20-PLCC footprint dimensions accurately. Validate that the system voltage rails remain strictly within the 3V to 3.6V operational window to prevent device damage.

Configuration PROMs For FPGAs Selection Notes

Select this component when designing systems based on Xilinx Spartan-3 or Spartan-3A architectures requiring robust, non-volatile configuration storage. The choice is driven by the need for high-density bitstream retention and enhanced security features compared to older generation PROMs. Consider the PLCC package constraints if space is limited but through-hole mounting is preferred over surface-mount alternatives.

Configuration PROMs For FPGAs Part Context

This part belongs to AMD's legacy configuration memory portfolio, specifically engineered to support Xilinx FPGA families. It serves as a critical bridge between the host processor and the programmable logic fabric, ensuring rapid and secure initialization. The product line emphasizes data integrity and long-term reliability for embedded applications where FPGA reconfiguration is not required after initial deployment.

Configuration PROMs For FPGAs Replacement Considerations

Direct substitutes include other AMD/Xilinx PROMs with equivalent 128 Mbit density and SPI compatibility, such as the XC17128E series variants. Verify pinout compatibility and voltage specifications before swapping. Cross-reference with current AMD datasheets to ensure no functional differences exist between manufacturing batches.
