AMD XC3042A-7PQ100C

Overview

XC3042A-7PQ100C from AMD is a Field-Programmable Gate Array (FPGA) featuring 4200 usable gates, 96 I/O pins, and a 7 ns maximum input-to-output delay. It implements configurable logic blocks, interconnect resources, and I/O cells for digital system prototyping and glue logic replacement in industrial control and communications equipment.

For engineers reviewing the XC3042A-7PQ100C datasheet, pinout, applications, or equivalent options, key selection factors include gate count, I/O count, speed grade, PQ100 package compatibility, and XACT development tool support.

Technical Context

This FPGA belongs to the XC3000A family and uses SRAM-based configuration memory with external PROM initialization. Logic is implemented via configurable logic blocks (CLBs), each containing two 3-input lookup tables and flip-flops with synchronous reset and clock enable.

Interconnect architecture includes segmented routing channels and switch matrices enabling flexible signal routing. The device supports mixed TTL/CMOS I/O levels and features programmable output slew rate control and input hysteresis for noise immunity.

FAQ

What is the configuration method for XC3042A-7PQ100C?

XC3042A-7PQ100C uses SRAM-based configuration loaded from an external serial PROM at power-up. The PROGRAM pin initiates configuration, and the DONE pin signals completion. No internal non-volatile memory is present, so configuration must be reloaded after each power cycle. This method enables rapid design iteration and field updates using standard XACT tools.

Does XC3042A-7PQ100C support mixed voltage I/O interfaces?

XC3042A-7PQ100C operates exclusively at 5 V and does not support mixed-voltage I/O. All inputs and outputs are TTL/CMOS-compatible with 5 V thresholds. Level-shifting circuitry is required when interfacing with 3.3 V or lower voltage devices. Input hysteresis helps maintain noise immunity but does not extend voltage range beyond 5 V specifications.

What development tools are compatible with XC3042A-7PQ100C?

XC3042A-7PQ100C is supported by AMD's XACT 5.x design suite, including schematic capture, logic synthesis, place-and-route, and bitstream generation. Third-party tools like Synopsys FPGA Express and Mentor Graphics Leonardo Spectrum were certified for use with this device. Simulation models are provided in Verilog and VHDL for timing-accurate verification.

How many global clock inputs does XC3042A-7PQ100C have?

XC3042A-7PQ100C has one dedicated global clock input pin (IOCLK) routed through a low-skew network to all CLBs. Additional clock signals may be distributed via general-purpose routing, but with higher skew and reduced timing predictability. For multi-clock domain designs, external clock management or internal PLLs are not available-clock domain crossing must be handled in logic.

Is XC3042A-7PQ100C RoHS compliant?

XC3042A-7PQ100C was manufactured prior to RoHS Directive enforcement and contains lead in its solder finish and die attach materials. It is classified as non-RoHS compliant. Aetrix Electronics provides full material declarations and can support legacy compliance documentation requests for industrial and medical applications where exemptions apply.
