AMD XC4005XL-2VQ100I

Overview

XC4005XL-2VQ100I from Xilinx is a Spartan-XL family FPGA with 5,000 usable gates, 100-pin VQFP package, -2 speed grade (12.5 ns CLB delay), and industrial temperature range (-40°C to +100°C). It implements synchronous digital logic in embedded control and interface bridging applications.

For engineers reviewing the XC4005XL-2VQ100I datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count (84 user I/Os), speed grade timing, VQFP thermal performance, and Spartan-XL configuration architecture compatibility.

Technical Context

The XC4005XL-2VQ100I uses a configurable logic block (CLB) architecture with four-input LUTs and flip-flops per CLB, supporting synchronous design with global clock routing. It features dedicated carry logic for arithmetic functions and distributed RAM capability up to 128 bits per CLB.

Configuration is performed via serial mode using an external PROM or parallel mode through the CPU interface. The device supports IEEE 1149.1 JTAG boundary-scan testing and in-system programmability via the JTAG port.

FAQ

What is the maximum operating frequency supported by XC4005XL-2VQ100I?

The XC4005XL-2VQ100I has a -2 speed grade specifying a 12.5 ns CLB propagation delay. This supports maximum system clock frequencies up to approximately 40 MHz for register-to-register paths under typical conditions. Actual achievable frequency depends on design topology, routing congestion, and I/O timing constraints - verified via Xilinx Foundation or ISE timing analysis tools using the XC4005XL-2VQ100I device model.

Does XC4005XL-2VQ100I support in-system programming?

Yes, XC4005XL-2VQ100I supports in-system programming via its IEEE 1149.1 JTAG interface (TMS, TDI, TDO, TCK pins). This enables configuration bitstream updates without removing the device from the PCB. The XC4005XL-2VQ100I does not support internal flash storage, so configuration remains volatile and requires external PROM or processor reload on power-up.

What voltage levels are supported on XC4005XL-2VQ100I I/O pins?

XC4005XL-2VQ100I I/O pins operate at 3.3 V LVTTL and LVCMOS logic levels, with input thresholds compatible with 5 V-tolerant signaling when used with appropriate series resistors. The core voltage (VCCINT) is strictly 3.3 V ± 3%, and I/O bank voltage (VCCO) must also be set to 3.3 V - no mixed-voltage I/O bank support is provided in the XC4005XL-2VQ100I.

Is XC4005XL-2VQ100I pin-compatible with other Spartan-XL devices in VQ100 package?

XC4005XL-2VQ100I is pin-compatible with other Spartan-XL devices in the VQ100 package, including XC4003XL-2VQ100I and XC4010XL-2VQ100I, sharing identical pin assignments for power, ground, clocks, JTAG, and configuration signals. I/O pin functions are consistent across the family, though usable gate count and CLB count differ - bitstream and timing constraints must be regenerated per device.

What configuration modes does XC4005XL-2VQ100I support?

XC4005XL-2VQ100I supports Master Serial, Slave Serial, and SelectMAP (parallel) configuration modes. Master Serial uses an external PROM connected to DIN and CCLK; Slave Serial allows configuration by a host processor; SelectMAP enables high-speed parallel loading via 8- or 16-bit data bus. All modes use the same XC4005XL-2VQ100I pin set, with mode selected by INIT and PROGRAM pin states during power-up.
