AMD XC4005E-2PC84C

Overview

XC4005E-2PC84C from Xilinx is a Field-Programmable Gate Array (FPGA) with 5,000 usable gates, 84-pin plastic leaded chip carrier (PLCC) package, -2 speed grade (12.5 ns maximum input-to-output delay), and commercial temperature range (0°C to 70°C). It implements synchronous digital logic in embedded control and interface bridging applications.

For engineers reviewing the XC4005E-2PC84C datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count (69 user I/Os), speed grade timing, PLCC-84 mechanical compatibility, and legacy 5 V CMOS interface support.

Technical Context

The XC4005E-2PC84C belongs to Xilinx's XC4000E FPGA family, built on 0.5 µm CMOS technology with configurable logic blocks (CLBs), input/output blocks (IOBs), and programmable interconnect. It supports SRAM-based configuration via JTAG or serial PROM.

It features dedicated carry logic for high-speed arithmetic, global clock routing, and three-state bus interface capability. Configuration is volatile and requires external memory reload on power-up.

Key Specifications

Pinout & Package

XC4005E-2PC84C uses an 84-pin Plastic Leaded Chip Carrier (PLCC) with J-lead geometry, 29.31 mm × 29.31 mm body size, and 1.27 mm lead pitch. Pin 1 is marked by a notch in the package corner.

Equivalent & Alternatives

The following parts are listed as comparable options for similar FPGA logic implementation applications.

Compared with XC4005E-2PC84C, the -3 variant trades 2.5 ns timing margin for lower dynamic power, while the XC4004E-2PC84C reduces gate capacity but improves compile time and reduces configuration bitstream size - both retain pin-for-pin compatibility and require no PCB changes.

Availability

XC4005E-2PC84C is available at Aetrix Electronics and suitable for industrial control, legacy system refurbishment, and embedded instrumentation requiring stable component supply over extended production lifecycles.

Supply support for XC4005E-2PC84C includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Xilinx, now part of AMD, pioneered commercial FPGA technology and developed scalable programmable logic architectures for high-reliability embedded systems.

The XC4000E family was designed for cost-sensitive, 5 V-based control and interface applications where long-term availability and mature toolchain support are critical.

FAQ

What is the maximum operating frequency supported by XC4005E-2PC84C?

The XC4005E-2PC84C has a -2 speed grade specifying a maximum input-to-output propagation delay of 12.5 ns. This translates to a theoretical maximum toggle frequency of approximately 40 MHz for simple register-to-register paths. Actual system clock frequency depends on logic depth, routing congestion, and I/O timing constraints - verified via Xilinx Foundation or Alliance software timing analysis.

Does XC4005E-2PC84C support in-system programming (ISP)?

XC4005E-2PC84C does not support true in-system programming due to its volatile SRAM configuration memory. It requires external configuration PROM or processor-controlled serial loading at power-up. JTAG boundary-scan (IEEE 1149.1) enables in-circuit testing and configuration bitstream download, but configuration is lost on power cycle.

What development tools are compatible with XC4005E-2PC84C?

XC4005E-2PC84C is supported by Xilinx Foundation Series 2.x and Alliance Series 2.x software suites. These include schematic capture, VHDL/Verilog synthesis, place-and-route, and timing simulation tools specifically validated for the XC4000E family. Third-party tools like Synplicity Synplify were also certified for this device.

Is XC4005E-2PC84C RoHS compliant?

XC4005E-2PC84C was manufactured prior to RoHS Directive enforcement and uses leaded solder in its PLCC package. It is not RoHS compliant. For RoHS-compliant alternatives, consider later-generation Spartan or Artix families - however, these require PCB redesign due to different packages, voltage levels, and toolchain requirements.

Can XC4005E-2PC84C operate with mixed 3.3 V and 5 V interfaces?

No. XC4005E-2PC84C is a 5 V-only device. Its I/O buffers are designed for 5 V TTL/CMOS logic levels and lack 3.3 V tolerance. Interfacing with 3.3 V systems requires external level-shifting circuitry such as dual-supply translators or resistor-divider networks with appropriate drive strength matching.
