XC95216-20HQ208I

Complex Programmable Logic Devices Overview

The XC95216-20HQ208I is a high-density Complex Programmable Logic Device (CPLD) from the Xilinx 9500XL family. It features 2,144 usable system gates and supports up to 216 macrocells within a single package. The device utilizes CMOS Flash memory technology, allowing for non-volatile configuration that retains data without external power. Key electrical specifications include a maximum operating frequency of 50 MHz at VCC = 5V and 33 MHz at VCC = 3V. It operates with a supply voltage range of 2.7V to 5.5V and offers I/O voltages compatible with both 3.3V and 5V systems, ensuring flexibility in mixed-voltage designs.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'HQ208I' corresponds to the Heat Sink Quad Flat Package (HSQFP) with 208 pins and Industrial temperature grade (-40°C to +85°C). Confirm authenticity through authorized distributors as counterfeit CPLDs exist. Check for RoHS compliance status if required by current manufacturing regulations. Ensure the ordering part number matches the exact speed grade '-20' for timing requirements.

Complex Programmable Logic Devices Selection Notes

Select this component when a non-volatile solution is required to eliminate external configuration EEPROMs. The 216 macrocell count is suitable for moderate complexity glue logic. Compare against the XC95216-20PC208 variant if a different package type is preferred. Consider the 5V tolerant I/O capability if interfacing with legacy 5V peripherals while the core operates at lower voltages.

Complex Programmable Logic Devices Part Context

This part belongs to the Xilinx 9500XL series, which succeeded the original 9500 series. The 9500XL line introduced improved performance and density using advanced Flash processes. It serves as a drop-in replacement for many older E²PROM-based CPLDs but offers faster reprogramming cycles and higher endurance. The HSQFP package provides thermal advantages over standard QFP variants.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may include other speed grades within the same package family, such as XC95216-15HQ208I or XC95216-25HQ208I, provided timing constraints allow. For functional equivalence in different packages, consider XC95216-20PC208I (PLCC) or XC95216-20TQ144I (TQFP), though pinouts will differ.
