XC9572XL-7VQG44C

Complex Programmable Logic Devices Overview

The XC9572XL-7VQG44C is a Complex Programmable Logic Device (CPLD) from the AMD XC9500XL series, manufactured by AMD/Xilinx. It features 72 macrocells and 1,600 usable gates organized into four Logic Array Blocks (LABs). The device operates at a supply voltage of 3.3 V (range 3.0 V to 3.6 V) with a maximum system frequency of 178 MHz and a typical propagation delay of 7.5 ns. It utilizes Flash memory technology for non-volatile configuration and supports in-system programming. The component is housed in a 44-pin Very Thin Quad Flat Package (VQFP) and is rated for an industrial temperature range of -40°C to +85°C.

• General-purpose programmable logic replacement for discrete gate arrays

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific manufacturing date codes against project requirements. Check for moisture sensitivity level (MSL) handling instructions if storage conditions exceed specified limits. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Complex Programmable Logic Devices Selection Notes

Select this model when 72 macrocells are sufficient for the design complexity and a 44-pin footprint is required. The 7.5 ns speed grade offers a balance between performance and power consumption compared to faster variants. Ensure the application environment stays within the -40°C to +85°C operating range. Verify that the 3.3V core voltage aligns with the target system's power rails.

Complex Programmable Logic Devices Part Context

This part belongs to the XC9500XL family, which introduced Flash technology to replace older EEPROM-based CPLDs, enabling easier in-system programming. The '7' suffix indicates the 7.5 ns speed grade, while 'VQG44' specifies the 44-pin VQFP package with industrial temperature rating. It serves as a drop-in replacement for many legacy PLD designs requiring higher density than the XC9500 series.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements may be limited due to obsolescence. Consider evaluating newer Xilinx Artix or Spartan FPGA families for new designs, though these require different toolchains and voltage configurations. Cross-reference with other manufacturers like Lattice or Microchip for equivalent gate counts and I/O capabilities.
