Detailed Product Description
What Makes the XC5210-4PC84C Unique?
The XC5210-4PC84C represents a significant advancement in FPGA technology from the late 1990s era, incorporating lessons learned from three previous generations of Xilinx FPGA families. Despite being classified as a legacy component not recommended for new designs, this device continues to serve critical roles in maintaining existing systems and applications where proven reliability is paramount.
The device’s VersaBlock architecture creates a “sea of logic cells” approach, where each Configurable Logic Block (CLB) is surrounded by two types of local interconnect. This hierarchical routing structure minimizes the use of general-purpose interconnect resources, resulting in faster implementation speeds and more predictable timing characteristics.
Package and Pin Configuration
The 84-pin PLCC package (PC84C designation) provides a compact footprint suitable for space-constrained applications. The package features:
- 50 User I/O Pins for application-specific connections
- 34 Additional Pins dedicated to configuration, power supply, and ground
- J-Lead Package Style for reliable surface-mount assembly
- Ceramic or Plastic Options depending on application requirements
Speed Grade Analysis
The -4 speed grade indicates standard performance characteristics within the XC5200 family. While not the fastest variant (which would be -3), the -4 grade offers an excellent balance between performance and cost-effectiveness for applications that don’t require maximum clock frequencies.

Frequently Asked Questions
What is the difference between XC5210-4PC84C and XC5210-5PC84C?
The primary difference lies in the speed grade. The -4 variant offers better performance (faster timing) compared to the -5 variant, making it suitable for applications requiring higher clock frequencies or tighter timing constraints.
Is the XC5210-4PC84C RoHS compliant?
As a legacy product from the 1990s era, original production units are not RoHS compliant. However, some suppliers may offer RoHS-compatible variants or substitutes for applications requiring environmental compliance.
Can the XC5210-4PC84C be used in automotive applications?
The commercial temperature grade (0°C to +85°C) makes this device suitable for some automotive applications. However, for critical automotive systems, industrial-grade (-40°C to +85°C) or automotive-qualified components are recommended.
What development tools are required?
Legacy Xilinx ISE software (version 8.2i or earlier) is typically required. Modern Vivado tools do not support the XC5200 family. The software runs on Windows, Linux, and older Unix workstations.
How long will the XC5210-4PC84C remain available?
As a discontinued product, availability depends on existing distributor inventory and aftermarket stock. For long-term projects, consider purchasing lifetime quantities or planning migration to current-generation FPGAs.
