• High-speed controllers and address decoding systems
• Peripheral bus interfaces and DSP functions
• Co-processor implementations

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's current datasheet to confirm package type and voltage specifications. Check for Product Change Notifications (PCN) regarding packaging or manufacturing location updates. Confirm RoHS3 compliance status for the specific revision. Ensure the ordering suffix matches the required lead-free and halogen-free requirements for your assembly process.

Selection Notes

Select this model when 24,000 system gates are sufficient for the design. Choose the PLCC-84 package if through-hole or specific footprint constraints apply. Verify that the 3V or 5V core voltage options meet the system power budget. Consider the 72 available I/O pins against interface requirements. Evaluate the need for the included dual-port SRAM for data buffering needs.

Part Context

This component belongs to the Microchip MX FPGA family, which bridges the gap between complex programmable logic devices and full-scale FPGAs. The series is known for its synthesis-friendly architecture and support for ASIC design methodologies. It allows for high pin-fixing and resource utilization, making it suitable for designs transitioning from discrete logic components.
