Visão Geral
Description
The XC3042A-7PC84C is a Field-Programmable Gate Array (FPGA) from Xilinx's XC3000 series, designed for flexible digital logic implementation. Key features:
- Logic Capacity: ~3,000 gates (42 CLBs).
- Speed: 7ns typical gate delay (-7 speed grade).
- Package: 84-pin PLCC (Plastic Leaded Chip Carrier).
- I/O: Up to 64 user I/O pins.
- Configuration: SRAM-based, requiring external ROM.
- Applications: Prototyping, glue logic, and embedded systems.
Introduced in the 1990s, it’s now obsolete but was notable for its reprogrammability and ease of use. Modern Xilinx FPGAs (e.g., Spartan, Artix) offer significantly higher performance.
For legacy designs, check Xilinx’s archived documentation or consider migration to newer families.
