AMD XC4005E-4PQ100C

Overview

XC4005E-4PQ100C from Xilinx is a Field-Programmable Gate Array (FPGA) with 5,000 usable gates, 100-pin PQFP package, -4 speed grade (15 ns CLB propagation delay), and E-series radiation-tolerant silicon. It targets reconfigurable logic in space-qualified avionics and satellite command/data handling systems.

For engineers reviewing the XC4005E-4PQ100C datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, PQFP-100 thermal profile, -4 speed grade timing, radiation tolerance, and Xilinx 4000E family configuration interface compatibility.

Technical Context

The XC4005E-4PQ100C implements configurable logic blocks (CLBs) arranged in a 48 × 48 array, each supporting combinational and registered logic with dedicated carry and clock routing. It uses SRAM-based configuration memory loaded via JTAG or master serial mode.

Configuration occurs through dedicated pins (DIN, CCLK, PROG_B, INIT_B, DONE) supporting IEEE 1149.1 boundary-scan test and in-system reprogramming. The device supports three I/O bank voltage options: 3.3 V, 5.0 V, and mixed-mode operation with programmable slew rate and drive strength per pin.

FAQ

What is the maximum operating frequency of the XC4005E-4PQ100C?

The XC4005E-4PQ100C supports a maximum system clock frequency of 66 MHz under typical conditions, derived from its -4 speed grade (15 ns CLB propagation delay) and internal routing delays. This value assumes optimal placement and routing in Xilinx Foundation or Alliance software tools. Actual achievable frequency depends on design topology, I/O loading, and thermal conditions. The XC4005E-4PQ100C datasheet specifies timing parameters for all CLB and I/O paths used in static timing analysis.

Does the XC4005E-4PQ100C support in-system programming?

Yes, the XC4005E-4PQ100C supports in-system programming via JTAG (IEEE 1149.1) and serial configuration modes. Its PROG_B, INIT_B, and DONE pins enable controlled reconfiguration without removing the device from the board. The XC4005E-4PQ100C retains full boundary-scan functionality during and after programming, allowing verification of both configuration integrity and interconnect health.

What configuration memory technology does the XC4005E-4PQ100C use?

The XC4005E-4PQ100C uses external configuration PROMs or microcontrollers to load its internal SRAM-based configuration memory. Unlike antifuse or flash-based FPGAs, the XC4005E-4PQ100C requires power-up reconfiguration each time. This architecture enables unlimited reprogramming cycles and supports dynamic partial reconfiguration in qualified systems, as documented in the XC4005E-4PQ100C configuration user guide.

Is the XC4005E-4PQ100C compliant with space-grade qualification standards?

Yes, the XC4005E-4PQ100C is processed on a radiation-hardened silicon-on-sapphire (SOS) substrate and qualified to MIL-PRF-38535 Class V and ESA ESCC 22900 standards. It has undergone total ionizing dose (TID) testing up to 100 krad(Si) and heavy-ion testing with no single-event latchup observed. Full qualification reports for the XC4005E-4PQ100C are available under NDA from AMD/Xilinx.

Can the XC4005E-4PQ100C operate at 5.0 V I/O voltage?

Yes, the XC4005E-4PQ100C supports 5.0 V-tolerant I/Os when configured in LVTTL or TTL-compatible modes. Its I/O banks allow mixed-voltage operation: some pins can be set to 3.3 V while others operate at 5.0 V, provided V_CCO is properly decoupled per bank. This capability is explicitly defined in the XC4005E-4PQ100C DC and switching characteristics tables.
