XC4005XL-1VQ100C

The XC4005XL-1VQ100C is a Field Programmable Gate Array (FPGA) from AMD's XC4000E/X family. It combines configurable logic resources, embedded memory, and flexible I/O in a 100-pin TQFP package for programmable digital designs.

With 196 CLBs, 466 logic elements and 6,272 bits of on-chip RAM, this device targets designs that require moderate logic density, local memory for buffering or state storage, and up to 77 I/O signals within a surface-mount 100-VQFP (14×14) footprint.

Key Features

• Configurable Logic 196 CLBs and 466 logic elements provide the programmable building blocks for implementing custom digital functions and control logic.
• Embedded Memory 6,272 bits of on-chip RAM suitable for small buffers, FIFOs, and state storage directly within the FPGA fabric.
• I/O Capacity 77 user I/O pins to support multiple interfaces and peripheral connections on a single device.
• System Logic Scale Approximately 5,000 gates of logic capacity for moderate-complexity designs and glue logic integration.
• Power Operates from a 3.0 V to 3.6 V supply range, supporting common 3.3 V system rails.
• Package & Mounting Available in a 100-TQFP / 100-VQFP (14×14) surface-mount package for compact PCB integration.
• Operating Range Commercial-grade operation from 0 °C to 85 °C suitable for standard embedded and consumer applications.
• Regulatory Compliance RoHS-compliant material designation for environmental and manufacturing consistency.

Typical Applications

• Custom Digital Logic and Prototyping — Implement and iterate on custom finite state machines, glue logic, and digital functions using the device's CLBs and logic elements.
• Interface and Peripheral Control — Use the 77 I/O pins to consolidate multiple peripheral interfaces and simplify board-level connectivity.
• Local Buffering and Small Memory Tasks — Leverage 6,272 bits of on-chip RAM for small buffering, lookup tables, and temporary data storage within embedded designs.
• Compact Embedded Systems — The 100-TQFP surface-mount package fits space-constrained PCBs where a moderate-density programmable device is required.
