Product details
Overview
XC4008E-2PC84C from Xilinx is a Field-Programmable Gate Array (FPGA) with 8,000 usable gates, 84-pin plastic leaded chip carrier (PLCC) package, -2 speed grade, 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 XC4008E-2PC84C datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count, speed grade, package compatibility, and legacy design support for rework or obsolescence mitigation.
Technical Context
The XC4008E-2PC84C belongs to the Xilinx XC4000E FPGA family, built on a 0.5 µm CMOS process. It features configurable logic blocks (CLBs), input/output blocks (IOBs), and programmable interconnect resources. Configuration is performed via serial or parallel mode using external PROM or microprocessor.
It supports IEEE Std 1149.1 (JTAG) boundary-scan testing and includes dedicated carry logic for high-speed arithmetic. The device uses SRAM-based configuration memory, requiring external configuration on power-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gates | 8,000 usable system gates - defines maximum combinational logic capacity for logic synthesis |
| Speed Grade | -2 - indicates 25 MHz maximum clock frequency for CLB-to-CLB paths under commercial conditions |
| Package | 84-pin PLCC (Plastic Leaded Chip Carrier) - surface-mount, JEDEC MO-047 compliant, 25.4 mm × 25.4 mm footprint |
| I/O Pins | 77 user-programmable I/Os - supports TTL/CMOS-compatible signaling with configurable drive strength |
| Configuration | SRAM-based, serial/parallel mode - requires external configuration PROM or processor-controlled loading at power-on |
| Temperature Range | 0°C to +70°C - suitable for commercial-grade board-level integration without extended thermal management |
Pinout & Package
XC4008E-2PC84C is housed in an 84-pin PLCC package with 22 pins per side and a 1.27 mm pitch. Pin 1 is marked by a corner notch; the package is lead-free compatible and RoHS-compliant per Xilinx documentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Core power supply | 5.0 V ±5% required for internal logic operation; decoupling capacitors mandatory near each VCC pin |
| GND | Ground reference | Common return path for all I/O and core circuits; multiple GND pins ensure low-impedance grounding |
| PROGRAM | Configuration reset | Active-low signal that clears SRAM configuration and initiates reconfiguration sequence |
| DIN | Serial configuration data input | Accepts bitstream during serial mode programming; synchronized to CCLK edge |
| CCLK | Configuration clock | Drives internal shift registers during configuration; externally generated or internally derived |
| INIT | Configuration status | Open-drain output indicating successful configuration completion or error condition |
| TCK/TMS/TDI/TDO | JTAG test interface | Supports IEEE 1149.1 boundary-scan for board-level test and in-system programming |
Key Features
| Feature | Design Value |
|---|---|
| Configurable CLBs | Each CLB contains two 3-input LUTs and flip-flops, enabling efficient implementation of sequential and combinatorial logic |
| Dedicated carry chain | Fast ripple-carry propagation across CLBs - reduces adder delay by up to 40% vs. general routing |
| Flexible I/O banking | IOBs support independent voltage referencing per bank, allowing mixed-voltage interface (e.g., 5V-tolerant inputs with 3.3V outputs) |
| JTAG boundary-scan | Enables automated PCB test, fault isolation, and in-system configuration without dedicated test fixtures |
| Power-on configuration | Automatically loads bitstream from external PROM upon power-up - eliminates manual programming step in production |

FAQ
What is the maximum operating frequency of the XC4008E-2PC84C?
The XC4008E-2PC84C has a -2 speed grade specifying a maximum CLB-to-CLB propagation delay of 25 ns, corresponding to a 25 MHz system clock frequency under commercial temperature and voltage conditions. Actual achievable frequency depends on design topology, routing congestion, and I/O timing constraints. The XC4008E-2PC84C datasheet provides detailed timing parameters for critical paths including carry chains and register-to-register delays.
Does the XC4008E-2PC84C support in-system programming?
Yes, the XC4008E-2PC84C supports in-system programming via its JTAG (TCK/TMS/TDI/TDO) interface compliant with IEEE Std 1149.1. This allows configuration bitstream updates without removing the device from the PCB. The XC4008E-2PC84C requires external configuration memory or host processor control for persistent storage, as its SRAM configuration is volatile.
What package type is used for the XC4008E-2PC84C?
The XC4008E-2PC84C uses an 84-pin Plastic Leaded Chip Carrier (PLCC) package, designated as PC84C in Xilinx nomenclature. It features a 25.4 mm × 25.4 mm body size, 1.27 mm lead pitch, and corner-notch pin 1 identification. The package is RoHS-compliant and compatible with standard PLCC socketing or reflow soldering processes.
Can the XC4008E-2PC84C be used in automotive applications?
No, the XC4008E-2PC84C is rated for commercial temperature range (0°C to +70°C) and is not qualified for automotive use. It lacks AEC-Q100 qualification, extended temperature grading, or enhanced reliability screening required for automotive ECUs. For automotive applications, Xilinx offers the XC4000XL or Spartan families with industrial or automotive temperature grades.
How many I/O pins does the XC4008E-2PC84C provide?
The XC4008E-2PC84C provides 77 user-programmable I/O pins within its 84-pin PLCC package. The remaining 7 pins are dedicated to power (VCC), ground (GND), configuration (PROGRAM, INIT, CCLK, DIN), and JTAG (TCK/TMS/TDI/TDO) functions. All I/Os support 5V-tolerant inputs and can be configured for various drive strengths and slew rates.
