Product details

Overview

XC4005E-4TQ144C from Xilinx is a Field-Programmable Gate Array (FPGA) with 5,000 usable gates, 144-pin TQFP package, -4 speed grade (15 ns CLB propagation delay), and embedded SRAM-based configuration memory. It serves as a reconfigurable logic fabric in digital control systems requiring moderate gate count and deterministic timing.

For engineers reviewing the XC4005E-4TQ144C datasheet, pinout, applications, or equivalent options, key selection criteria include CLB count, I/O pin availability, TQFP thermal performance, and compatibility with Xilinx Foundation or Alliance software toolchains.

Technical Context

The XC4005E-4TQ144C implements a hierarchical architecture with Configurable Logic Blocks (CLBs), Input/Output Blocks (IOBs), and interconnect resources. Each CLB contains two 3-input lookup tables (LUTs) and flip-flops supporting synchronous edge-triggered operation.

Configuration is performed via serial mode using the JTAG boundary-scan interface or parallel mode through dedicated configuration pins. The device supports in-system programmability and retains configuration only while powered; external PROM is required for power-up initialization.

Key Specifications

Parameter	Value and Actual Design Meaning
Gates	5,000 usable system gates - defines maximum combinational logic capacity for logic synthesis mapping
CLBs	192 CLBs - each provides dual 3-LUTs + flip-flop, enabling efficient register-rich designs
I/O Pins	111 user I/O pins - supports mixed-voltage interfacing with 3.3 V or 5 V tolerant inputs
Speed Grade	-4 (15 ns CLB t_PD) - guarantees worst-case propagation delay for timing-critical paths
Package	TQFP-144 (20 × 20 mm, 0.5 mm pitch) - enables manual soldering and standard PCB assembly
V_CCINT	5.0 V ± 5% - powers internal logic; requires local decoupling per Xilinx layout guidelines

Pinout & Package

XC4005E-4TQ144C is housed in a 144-lead Thin Quad Flat Pack (TQFP) with exposed thermal pad, JEDEC MO-152AC compliant. Pin 1 is marked by a corner notch or dot; pin numbering proceeds counterclockwise.

Pin/Terminal	Circuit Role	Design Meaning
GND	Ground reference	Multiple dedicated pins (e.g., Pins 1, 2, 143, 144) - must be connected to low-inductance ground plane
V_CCINT	Core logic supply	Pins 72, 73, 108 - requires 5 V ± 5% with ≥10 µF bulk + 0.1 µF ceramic decoupling
PROGRAM	Configuration reset	Pin 117 - active-low signal that clears configuration memory and initiates reload sequence
DIN	Serial config data input	Pin 116 - accepts bitstream during JTAG or serial mode programming
TCK/TMS/TDI/TDO	JTAG test access	Pins 113–116 - enable IEEE 1149.1 boundary-scan testing and in-system programming

Key Features

Feature	Design Value
SRAM-based configuration	Enables full reprogrammability in-system without socket removal or UV erasure
Dual-edge flip-flops per CLB	Supports time-multiplexed logic and high-frequency register-to-register paths
Three-state bus-hold on I/Os	Maintains last valid logic state when inputs float, reducing need for external pull-ups
Configurable I/O standards	Per-pin setup allows mix of LVTTL, TTL, and CMOS-compatible drive strengths
JTAG boundary-scan support	Provides IEEE 1149.1-compliant test access for board-level diagnostics and programming

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
XC4005E-3TQ144C	Faster -3 speed grade (12 ns CLB t_PD); otherwise identical architecture and pinout	Suitable where tighter timing margins are required without changing PCB layout	Select when design timing closure fails at -4 grade but no I/O or resource change is needed

FAQ

What is the configuration method supported by XC4005E-4TQ144C?

The XC4005E-4TQ144C supports both JTAG boundary-scan (IEEE 1149.1) and master serial configuration modes. Configuration bitstream is loaded into internal SRAM cells; no external nonvolatile memory is integrated. The XC4005E-4TQ144C requires external PROM or microcontroller-driven initialization at power-up.

Does XC4005E-4TQ144C support hot-swap or live-insertion?

No, XC4005E-4TQ144C does not support hot-swap operation. Its I/O structure lacks bus-hold or power-on reset circuitry required for safe insertion under power. Power sequencing must follow Xilinx-recommended order: V_CCINT before V_CCO, with all supplies stable before releasing PROGRAM pin.

What software tools are compatible with XC4005E-4TQ144C?

XC4005E-4TQ144C is fully supported by Xilinx Foundation Series 2.x and Alliance Series 2.x design suites. Synthesis, place-and-route, and bitstream generation workflows are validated for this device. The XC4005E-4TQ144C is not supported in modern Vivado or ISE 14.x+ toolchains.

Can XC4005E-4TQ144C operate at 3.3 V I/O levels?

Yes, XC4005E-4TQ144C IOBs are 5 V-tolerant and support 3.3 V LVTTL signaling when V_CCO is set to 3.3 V. Internal core remains at 5 V. This allows direct interfacing with 3.3 V microcontrollers while maintaining compatibility with legacy 5 V peripherals.

Is XC4005E-4TQ144C RoHS compliant?

XC4005E-4TQ144C was manufactured prior to RoHS Directive enforcement and is not RoHS compliant. It contains lead in solder finish and die attach materials. For RoHS-compliant alternatives, consult AMD/Xilinx documentation for pin-compatible replacements in the Spartan or Artix families.
