AMD XC4006E-3PG156C

Overview

XC4006E-3PG156C from Xilinx is a Field-Programmable Gate Array (FPGA) with 6,000 usable gates, 156-pin plastic quad flat pack (PQFP) package, 3.3 V I/O voltage, and -3 speed grade (12 ns CLB propagation delay). It implements synchronous digital logic in embedded control and interface bridging applications.

For engineers reviewing the XC4006E-3PG156C datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O voltage compatibility, speed grade timing, PQFP thermal and routing constraints, and legacy 4000E family configuration requirements.

Technical Context

The XC4006E-3PG156C belongs to Xilinx's 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.

It supports JTAG boundary-scan (IEEE 1149.1) for testing and in-system programming, and uses external PROM or microprocessor-controlled configuration. The -3 speed grade guarantees maximum 12 ns CLB-to-CLB delay and 8.5 ns IOB-to-IOB delay under specified conditions.

Key Specifications

FAQ

What is the core supply voltage requirement for XC4006E-3PG156C?

The XC4006E-3PG156C requires a 5.0 V ±5% core supply (VCC) for internal logic operation, while its I/O banks operate at 3.3 V. Both supplies must be independently regulated and decoupled per Xilinx XC4000E design guidelines to ensure stable configuration and switching behavior.

Does XC4006E-3PG156C support in-system programming?

Yes, XC4006E-3PG156C supports in-system programming via its JTAG port (TCK/TMS/TDI/TDO) compliant with IEEE 1149.1. Configuration bitstream can be loaded dynamically through boundary-scan, enabling field updates without removing the device from the PCB.

What configuration modes does XC4006E-3PG156C support?

XC4006E-3PG156C supports master serial, slave serial, and slave parallel configuration modes. It loads configuration data from external PROM or microcontroller upon power-up or PROGRAM pin assertion, with INIT pin signaling completion or failure.

Is XC4006E-3PG156C RoHS compliant?

No, XC4006E-3PG156C is a legacy device manufactured prior to RoHS Directive enforcement and contains leaded solder in its 156-pin PQFP package. It is exempt from RoHS under the "legacy components" provision for repair and obsolescence management.

Can XC4006E-3PG156C be used in new designs today?

XC4006E-3PG156C remains viable for sustaining engineering, repair, and legacy system upgrades where form-fit-function match and long-term availability are critical. New designs should evaluate modern alternatives unless backward compatibility with existing hardware and toolchains is mandatory.
