Product details

Overview

XC4005E-3PC84I from Xilinx is a Field-Programmable Gate Array (FPGA) with 5,000 usable gates, 84-pin plastic leaded chip carrier (PLCC) package, -3 speed grade (12.5 ns CLB propagation delay), and industrial temperature range (-40°C to +100°C). It implements synchronous digital logic in embedded control and interface bridging applications.

For engineers reviewing the XC4005E-3PC84I 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 Xilinx 4000E family configuration requirements.

Technical Context

The XC4005E-3PC84I belongs to the Xilinx 4000E FPGA family, built on 0.5 µm CMOS technology. It contains configurable logic blocks (CLBs), input/output blocks (IOBs), and interconnect resources programmable via SRAM-based configuration bitstream loaded at power-up.

Configuration is performed through JTAG boundary-scan (IEEE 1149.1) or master serial mode using an external PROM. The device supports 5 V TTL-compatible I/Os and requires external configuration memory for persistent operation.

Key Specifications

Parameter	Value and Actual Design Meaning
Gates	5,000 usable system gates - determines maximum combinational logic density for state-machine or glue-logic replacement
Speed Grade	-3 (12.5 ns CLB t_PD) - defines worst-case propagation delay through a single CLB for timing-critical paths
Package	84-pin PLCC (29.31 mm × 29.31 mm) - surface-mount, socket-compatible footprint with thermal and mechanical constraints for legacy PCBs
User I/Os	69 - number of bidirectional, 5 V-tolerant pins available for interfacing with microcontrollers, memories, or peripherals
Operating Temp	-40°C to +100°C - qualified for industrial environments without derating or forced cooling
V_CC	5.0 V ± 5% - single-supply requirement; no auxiliary voltage rails needed

Pinout & Package

XC4005E-3PC84I uses an 84-pin Plastic Leaded Chip Carrier (PLCC) with J-lead geometry, 0.05 inch pitch, and center power/ground pad layout optimized for thermal dissipation in high-density layouts.

Pin/Terminal	Circuit Role	Design Meaning
PIN 1–69	User I/O	Bidirectional, 5 V-tolerant, configurable as input, output, or tristate; includes slew-rate control and pull-up resistors
PIN 70, 71, 72	V_CC	Main 5 V supply inputs - must be decoupled locally with 0.1 µF ceramic capacitors per pair
PIN 73–84	GND	Ground return paths - distributed across corners and edges to minimize ground bounce in high-speed switching
PIN 83	PROGRAM	Active-low configuration initialization signal - forces reload of configuration bitstream from external PROM
PIN 84	INIT	Open-drain status indicator - goes low during configuration, high when configuration completes successfully

Key Features

Feature	Design Value
SRAM-based configuration	Enables in-system reprogramming without socket removal; requires external nonvolatile PROM for power-on restore
JTAG boundary-scan support	Allows IEEE 1149.1-compliant testing, debugging, and in-circuit configuration without dedicated programming hardware
5 V tolerant I/Os	Interoperates directly with legacy TTL, LVTTL, and 5 V microcontrollers without level-shifting circuitry
Configurable slew-rate control	Reduces EMI and signal integrity issues by limiting edge rates on selected outputs in noise-sensitive environments

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
XC4005E-4PC84I	Slower -4 speed grade (15 ns CLB t_PD); otherwise identical architecture, pinout, and configuration interface	Suitable where timing margins exceed 12.5 ns; lower power consumption at same frequency	Select if design operates below 66 MHz and prioritizes reduced dynamic power over maximum clock frequency
XCR3064XL-10VQG44C	CMOS-based CPLD (not SRAM FPGA); 64 macrocells; 100-pin VQFP; 3.3 V core; no configuration memory required	Better for fixed-function glue logic with deterministic timing; unsuitable for large sequential state machines or RAM-based functions	Choose for simpler, lower-power, instant-on applications where reprogrammability is secondary to predictability and zero-configuration startup

Compared with XC4005E-3PC84I, the -4 variant trades speed for margin and power, while the XCR3064XL offers deterministic CPLD timing and 3.3 V operation but lacks SRAM-based flexibility and gate density - selection depends on whether the design requires reconfigurable logic fabric or fixed, low-latency combinatorial logic.

FAQ

What is the configuration method supported by XC4005E-3PC84I?

The XC4005E-3PC84I supports master serial configuration using an external PROM and IEEE 1149.1 JTAG boundary-scan. Configuration bitstream is loaded into internal SRAM at power-up. No internal nonvolatile memory is present, so external configuration storage is mandatory for persistent operation. The XC4005E-3PC84I does not support slave parallel or selectMAP modes.

Does XC4005E-3PC84I require external voltage regulators?

No, the XC4005E-3PC84I operates from a single 5.0 V ± 5% supply. It has no auxiliary voltage rails or internal voltage regulation. Decoupling capacitors (0.1 µF ceramic per V_CC/GND pair) are required near the 84-pin PLCC package to ensure stable operation under switching loads. The XC4005E-3PC84I draws up to 250 mA typical depending on logic utilization and toggle rate.

Is XC4005E-3PC84I pin-compatible with other XC4000E devices?

Yes, the XC4005E-3PC84I shares the same 84-pin PLCC footprint and pin assignment with all XC4000E family members in the PC84 package, including XC4003E, XC4004E, and XC4006E variants. Signal names, I/O types, and power/ground pin locations are identical - only gate count and speed grade differ. This allows direct substitution within the same package option.

What is the maximum operating frequency achievable with XC4005E-3PC84I?

The XC4005E-3PC84I is rated for a 12.5 ns CLB propagation delay (t_PD), supporting system clock frequencies up to approximately 66 MHz in typical register-to-register paths. Actual maximum frequency depends on design topology, routing congestion, and I/O timing constraints. The XC4005E-3PC84I does not specify a guaranteed f_MAX for full-chip operation; timing analysis must be performed per implementation using Xilinx Foundation or Alliance software.

Can XC4005E-3PC84I be used in new designs today?

Yes, the XC4005E-3PC84I remains viable for legacy system repair, military sustainment, and industrial retrofit projects where 5 V TTL compatibility, PLCC packaging, and proven radiation-tolerant behavior are required. While newer FPGAs offer higher density and lower power, the XC4005E-3PC84I provides documented long-term availability and mature toolchain support. Aetrix Electronics maintains traceable inventory of genuine XC4005E-3PC84I units.
