AMD XC4008E-3PQ160C

Overview

XC4008E-3PQ160C from Xilinx is a Field-Programmable Gate Array (FPGA) with 8,000 usable gates, 160-pin Plastic Quad Flat Package (PQFP), -3 speed grade (12.5 ns CLB propagation delay), and commercial temperature range (0°C to 70°C). It implements synchronous digital logic in embedded control, protocol bridging, and glue-logic replacement applications.

For engineers reviewing the XC4008E-3PQ160C datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count (118 user I/Os), speed grade timing, PQFP thermal and routing constraints, and legacy 5V CMOS compatibility.

Technical Context

The XC4008E-3PQ160C belongs to the Xilinx XC4000E FPGA family, built on a 0.5 µm CMOS process. It features configurable logic blocks (CLBs) with four-input LUTs, dedicated carry logic for arithmetic, and flexible interconnect with segmented routing channels.

It supports in-system configuration via JTAG boundary-scan (IEEE 1149.1 compliant) and serial PROM loading. The device uses 5V supply voltage and provides TTL-compatible I/Os with programmable slew rate and drive strength.

Manufacturer

Xilinx, now part of AMD, pioneered commercial FPGA technology and developed the XC4000 family as the industry's first widely adopted SRAM-based programmable logic platform.

The XC4000E product line was designed specifically for cost-sensitive, medium-complexity digital logic replacement in commercial and industrial systems using mature 5V infrastructure.

FAQ

What is the maximum operating frequency supported by the XC4008E-3PQ160C?

The XC4008E-3PQ160C has a -3 speed grade specifying 12.5 ns CLB propagation delay. Its practical maximum system clock frequency depends on design topology but typically reaches 40–50 MHz for fully pipelined logic. Critical paths involving carry chains or long interconnect may limit performance below this range. The XC4008E-3PQ160C does not guarantee operation above 66 MHz under worst-case conditions.

Does the XC4008E-3PQ160C support in-system programming without external configuration PROM?

Yes, the XC4008E-3PQ160C supports in-system programming via its IEEE 1149.1 JTAG interface (TCK/TMS/TDI/TDO pins). This allows configuration bitstream loading directly from a host processor or debugger without requiring an external serial PROM. The XC4008E-3PQ160C retains configuration only while powered; SRAM-based architecture necessitates reload on power-up unless supplemented with nonvolatile storage.

What are the power supply requirements for the XC4008E-3PQ160C?

The XC4008E-3PQ160C requires a single 5.0 V ± 5% supply for both core logic and I/O banks. Total power consumption varies with toggle rate and design utilization but typically ranges from 250 mW (idle) to 1.1 W (fully active). Decoupling capacitors (0.1 µF ceramic near each V_CC pin) are mandatory. The XC4008E-3PQ160C does not support 3.3V or dual-supply operation.

Can the XC4008E-3PQ160C be used in industrial temperature environments?

No, the XC4008E-3PQ160C is specified only for commercial temperature range (0°C to +70°C). It lacks qualification for extended temperature grades such as –40°C to +85°C. Using the XC4008E-3PQ160C outside its rated range risks configuration loss, timing violation, or permanent damage. Industrial applications require alternative devices like the XC4008E-3PQ160I (industrial grade).

How many user I/O pins does the XC4008E-3PQ160C provide?

The XC4008E-3PQ160C provides 118 user-programmable I/O pins in its 160-pin PQFP package. The remaining 42 pins are dedicated to power (V_CC, GND), configuration (PROGRAM, DONE, INIT), clocks (GCK1–GCK4), and JTAG (TCK/TMS/TDI/TDO). All 118 I/Os support 5V TTL/CMOS levels and can be individually configured as input, output, or bidirectional with slew-rate control.
