AMD XC4005E-3PQ208C

Overview

XC4005E-3PQ208C from Xilinx is a Field-Programmable Gate Array (FPGA) with 5,000 usable gates, 208-pin Plastic Quad Flat Package (PQFP), -3 speed grade (12.5 ns CLB delay), and commercial temperature range (0°C to 70°C). It implements synchronous digital logic in embedded control, protocol bridging, and interface adaptation applications.

For engineers reviewing the XC4005E-3PQ208C datasheet, pinout, applications, or equivalent options, key selection factors include CLB count, I/O pin count, speed grade timing, configuration mode support, and TCK/TMS/TDI/TDO boundary-scan compliance.

Technical Context

The XC4005E-3PQ208C uses Xilinx's second-generation FPGA architecture with configurable logic blocks (CLBs), input/output blocks (IOBs), and interconnect resources. It supports in-system configuration via JTAG (IEEE 1149.1) and master serial mode using external PROM.

Each CLB contains two 3-input lookup tables (LUTs), flip-flops with synchronous reset, and carry logic for arithmetic functions. The device includes 192 user I/O pins, global clock routing, and dedicated high-fanout nets for clock and reset distribution.

Key Specifications

Pinout & Package

XC4005E-3PQ208C is available at Aetrix Electronics and suitable for industrial motion control, medical imaging subsystems, legacy bus interface adapters, and automated test equipment requiring stable component supply across extended production lifecycles.

Supply support for XC4005E-3PQ208C 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 and communications systems.

The XC4000E family was designed for cost-sensitive, medium-complexity logic replacement in industrial, medical, and test equipment where reprogrammability and I/O flexibility were critical.

FAQ

What is the maximum operating frequency supported by XC4005E-3PQ208C?

The XC4005E-3PQ208C has a -3 speed grade specifying 12.5 ns CLB propagation delay. Its practical maximum system clock frequency depends on design topology, but synchronous logic paths can achieve up to 65 MHz under typical PCB routing and loading conditions. The device does not specify a fixed maximum clock frequency; timing analysis must be performed per implementation using Xilinx Foundation or Alliance software tools.

Does XC4005E-3PQ208C support in-system programming?

Yes, XC4005E-3PQ208C supports in-system programming via its IEEE 1149.1 JTAG port (TCK/TMS/TDI/TDO). Configuration bitstream can be loaded directly into SRAM through JTAG without removing the device from the board, enabling field updates and manufacturing test automation.

What configuration modes are available for XC4005E-3PQ208C?

XC4005E-3PQ208C supports master serial mode (using external PROM), slave serial mode (driven by external controller), and JTAG boundary-scan mode. All three modes load configuration data into internal SRAM upon power-up or PROGRAM* assertion, with DONE pin signaling completion.

Is XC4005E-3PQ208C pin-compatible with other XC4000E family members in PQ208 package?

XC4005E-3PQ208C shares the same 208-pin PQFP footprint and pin assignment with XC4005E-4PQ208C and XC4005E-5PQ208C. However, it is not pin-compatible with higher-density variants like XC4010E-3PQ208C due to differing I/O bank assignments and voltage reference pin placements.

What is the I/O voltage tolerance of XC4005E-3PQ208C?

XC4005E-3PQ208C IOBs support 5 V-tolerant inputs when VCCO = 3.3 V or 5 V, allowing direct interfacing with TTL and CMOS logic families. Outputs swing rail-to-rail based on VCCO setting, and input thresholds comply with both TTL and CMOS specifications depending on VCCO level.
