AMD XC4005L-5PQ100C

Overview

XC4005L-5PQ100C from Xilinx is a low-voltage, 3.3 V, third-generation Field-Programmable Gate Array (FPGA) with 5,000 usable logic gates, 196 Configurable Logic Blocks (CLBs), and 112 user I/O pins in a 100-pin PQFP package. It integrates on-chip Select-RAM memory with synchronous write and dual-port modes, dedicated carry logic, and eight global low-skew clock networks - enabling PCI-compliant 66 MHz system operation in embedded control and digital signal preprocessing applications.

For engineers reviewing the XC4005L-5PQ100C datasheet, pinout, applications, or equivalent options, key selection criteria include its 3.3 V supply compatibility, 112-user-I/O count, -5 speed grade timing (T_PD ≤ 5.0 ns CLB-to-CLB), PCI compliance, and backward bitstream compatibility with XC4000 devices.

Technical Context

The XC4005L-5PQ100C implements a regular array of 14×14 CLBs interconnected by hierarchical routing resources, including longlines, double-length lines, and segmented lines. Each CLB contains two 4-input function generators (F/G), a 3-input H generator, dual edge-triggered D flip-flops, and configurable RAM modes (16×2 single-port, 32×1, or 16×1 dual-port).

It supports IEEE 1149.1 boundary scan, programmable I/O slew rate, input pull-up/pull-down resistors, and global clock enable (EC) and set/reset (SR) controls. Its -5 speed grade guarantees maximum toggle rates up to 150 MHz internally and 66 MHz synchronous system clock operation.

Key Specifications

Pinout & Package

XC4005L-5PQ100C is housed in a 100-pin Plastic Quad Flat Package (PQFP) with 0.65 mm lead pitch, JEDEC MS-026AC compliant, and 14 × 14 mm body size. Pinout follows standard XC4000L series I/O ring layout with dedicated configuration pins (M0–M2, PROGRAM, INIT, DONE), eight global clock inputs (GCLK0–GCLK7), and dual-purpose I/Os supporting TTL/CMOS thresholds.

Manufacturer

Xilinx, Inc. was a pioneering semiconductor company specializing in programmable logic devices, acquired by AMD in 2022. It developed industry-standard FPGA architectures and design tools for high-performance digital systems.

The XC4000L family was engineered as the low-voltage evolution of the XC4000E series - delivering 3.3 V operation, reduced power consumption, and full functional equivalence for industrial and communications applications demanding long-term availability and design stability.

FAQ

What is the maximum operating frequency of the XC4005L-5PQ100C?

The XC4005L-5PQ100C supports a synchronous system clock frequency up to 66 MHz, with internal toggle rates exceeding 150 MHz. This is guaranteed by its -5 speed grade, which specifies a maximum CLB-to-CLB propagation delay of 5.0 ns under worst-case conditions (3.0 V, 85°C). Actual performance depends on design placement and routing but remains bounded by this silicon-limited timing spec.

Does the XC4005L-5PQ100C support in-system programming?

Yes, the XC4005L-5PQ100C supports in-system programming via its IEEE 1149.1 (JTAG) boundary scan interface. Configuration data can be loaded through the TDI/TDO pins using standard JTAG commands, enabling field updates and debugging without removing the device from the PCB. The XC4005L-5PQ100C also supports slave serial and slave parallel modes for configuration from microcontrollers or PROMs.

Is the XC4005L-5PQ100C pin-compatible with other XC4000-series devices?

Yes, the XC4005L-5PQ100C shares identical pinout and footprint with the XC4005E-5PQ100C and XC4005XL-5PQ100C in the same PQFP-100 package. All three variants use the same I/O ring layout, configuration pin assignments (M0–M2, PROGRAM, INIT, DONE), and global clock pin locations - allowing direct PCB substitution where voltage and timing requirements align.

What types of on-chip memory does the XC4005L-5PQ100C provide?

The XC4005L-5PQ100C provides distributed Select-RAM memory within each of its 196 CLBs. Each CLB supports configurable RAM modes: 16×2 single-port (asynchronous or synchronous write), 32×1 single-port, or 16×1 dual-port (simultaneous read/write). Memory content is loaded during configuration, enabling deterministic startup states for FIFOs, lookup tables, and register files without external memory.

Can legacy XC4000 bitstreams be used with the XC4005L-5PQ100C?

Yes, the XC4005L-5PQ100C is bitstream-compatible with the original XC4000 family - meaning existing XC4000 bitstreams load and operate correctly. However, XC4005L-5PQ100C bitstreams cannot be loaded into older XC4000 devices due to architectural extensions like Select-RAM and enhanced carry logic. This one-way compatibility enables seamless migration of legacy designs to lower-voltage operation.
