AMD XC4006E-4PG156C

Overview

XC4006E-4PG156C from Xilinx is a Field-Programmable Gate Array (FPGA) with 600 logic cells, 156-pin plastic quad flat pack (PQFP) package, -4 speed grade, and 5V supply voltage. It implements synchronous digital logic in embedded control, protocol bridging, and glue-logic replacement applications.

For engineers reviewing the XC4006E-4PG156C datasheet, pinout, applications, or equivalent options, key considerations include logic cell count, I/O count (118 user I/Os), speed grade (-4 = 20 ns CLB delay), 5V CMOS compatibility, and configuration via serial PROM or parallel mode.

Technical Context

The XC4006E-4PG156C belongs to Xilinx's XC4000E FPGA family, built on 0.5 µm CMOS technology. It features configurable logic blocks (CLBs), input/output blocks (IOBs), and interconnect resources programmable via SRAM-based configuration memory.

Configuration is performed through JTAG boundary-scan (IEEE 1149.1), master serial, or slave parallel modes. The device supports in-system reprogrammability and includes dedicated carry logic for arithmetic functions and distributed RAM capability per CLB.

FAQ

What is the maximum operating frequency of the XC4006E-4PG156C?

The XC4006E-4PG156C has a -4 speed grade specifying a maximum CLB propagation delay of 20 ns. This translates to a theoretical maximum system clock frequency of approximately 50 MHz for register-to-register paths under typical conditions, though actual achievable frequency depends on design topology, routing, and I/O timing constraints.

Does the XC4006E-4PG156C support in-system programming?

Yes, the XC4006E-4PG156C supports in-system programming via its JTAG port (IEEE 1149.1 compliant) or through serial/parallel configuration modes. Configuration memory is SRAM-based, allowing full reprogramming without device removal, provided proper voltage and clock sequencing per Xilinx DS005 specification.

What package type is used for the XC4006E-4PG156C?

The XC4006E-4PG156C uses a 156-lead plastic quad flat pack (PQFP) package with 0.65 mm lead pitch and 24.0 mm × 24.0 mm body dimensions. It is RoHS-compliant and designed for reflow soldering per Xilinx packaging specifications.

Can the XC4006E-4PG156C operate at 3.3V?

No, the XC4006E-4PG156C is specified for 5.0 V ± 5% core and I/O supply only. It is not 3.3V-tolerant. Attempting 3.3V operation will result in incorrect logic states, configuration failure, or permanent damage. Level-shifting circuitry is required for interfacing with 3.3V systems.

How many user I/O pins does the XC4006E-4PG156C provide?

The XC4006E-4PG156C provides 118 user-configurable I/O pins. These support 5V TTL/CMOS signaling levels and can be individually configured as inputs, outputs, or bidirectional ports with programmable slew rate and drive strength per Xilinx XC4000E family documentation.
