FAQ

What is the primary function of the XC17128EVO8C in FPGA systems?

The XC17128EVO8C serves as a non-volatile configuration memory for Xilinx 4000-series FPGAs, storing and delivering the bitstream required for device initialization at power-on. Its serial interface and timing parameters are specifically aligned with Xilinx FPGA configuration protocols, ensuring reliable and deterministic startup without external controllers. The XC17128EVO8C eliminates the need for complex configuration circuitry in legacy FPGA designs.

Does the XC17128EVO8C support in-system programming?

Yes, the XC17128EVO8C supports in-system programming using a 12.5 V VPP supply applied to the VPP pin during write/erase cycles. This allows field reprogramming with compatible PROM programmers that adhere to AMD's XC1700 specification. The XC17128EVO8C does not require removal from the PCB, enabling firmware updates without hardware intervention or board disassembly.

What is the maximum clock frequency supported during XC17128EVO8C read operations?

The XC17128EVO8C supports read operations up to 6 MHz, derived from its 150 ns access time specification and timing margins defined in the AMD XC1700 datasheet. This frequency aligns with the configuration clock limits of Xilinx XC4000E and XC4000XLA FPGAs. The XC17128EVO8C maintains valid data hold times across the full industrial temperature range, ensuring robust bitstream delivery.

Is the XC17128EVO8C pin-compatible with Xilinx-branded configuration PROMs?

Yes, the XC17128EVO8C is pin-compatible and functionally equivalent to Xilinx XC17128DVO8C and XC17128EVO8C variants, sharing identical SOIC-8 pinout, signal definitions, and timing behavior. The XC17128EVO8C was designed explicitly as a second-source replacement, maintaining full interoperability with existing Xilinx FPGA configuration circuits and layout footprints.

What packaging and compliance information applies to the XC17128EVO8C?

The XC17128EVO8C is supplied in an 8-pin SOIC package with lead-free (Pb-free) construction compliant with RoHS Directive 2011/65/EU. It meets JEDEC MS-012 standards for SOIC dimensions and thermal performance. The XC17128EVO8C carries no halogen content per IEC 61249-2-21 and is qualified for moisture sensitivity level 1 (MSL-1), eliminating bake requirements prior to assembly.
