XC4005-5PQ208C

The XC4005-5PQ208C is a field-programmable gate array (FPGA) device from the XC4000 family, designed around a matrix of configurable logic blocks and a perimeter of programmable I/O. It delivers mid-range gate density and on-chip memory for reprogrammable digital logic, with a 208-pin BFQFP surface-mount package for board-level integration.

Built for applications that require hardware reconfiguration and iterative development, the device combines 466 logic element cells, approximately 6,272 bits of embedded RAM, and 112 programmable I/O pins while operating from a 4.75 V to 5.25 V supply within a commercial 0 °C to 85 °C temperature range.

Key Features

• Logic Capacity — 466 logic element cells and a CLB matrix totaling 196 CLBs provide mid-range programmable logic resources for custom digital functions.
• Embedded Memory — 6,272 total RAM bits of on-chip ultra‑fast RAM for small tables, FIFOs, and temporary storage without external memory.
• I/O and Drive — 112 programmable I/O pins allow flexible interfacing to peripherals and system buses; device family supports programmable output slew and pull-ups/pull-downs per the series description.
• Arithmetic and Timing — Dedicated high-speed carry-propagation circuitry and an eight‑node global low-skew clock/signal distribution network, as described for the family, enable efficient arithmetic and synchronous designs.
• Configurable Architecture — Reprogrammable internal configuration memory supports multiple programming modes and unlimited reprogramming for design iteration and field upgrades.
• Package & Mounting — 208‑BFQFP (208‑PQFP, 28 × 28) surface-mount package for compact PCB layouts and assembly.
• Power & Temperature — Operates from 4.75 V to 5.25 V with a commercial operating temperature range of 0 °C to 85 °C.
• Family-Level Tools — The XC4000 family is supported by development software and design tools for schematic entry, simulation, placement and routing, and configuration bitstream generation, as noted in the series documentation.
• Standards & Testability — Family documentation lists IEEE 1149.1-compatible boundary-scan support for testability (series feature).
• RoHS Compliant — Device is marked as RoHS compliant.

Typical Applications

• Rapid hardware prototyping: Use the reprogrammable logic and on-chip RAM to iterate designs quickly during development and evaluation phases.
• Reconfigurable systems: Implement hardware that must be retargeted or updated in the field through unlimited reprogramming.
• Moderate-volume production: Suitable for production deployments that leverage FPGA flexibility while keeping BOM complexity low.

Unique Advantages

• Reprogrammability: Unlimited device reprogramming supports design iteration, in-field updates, and multiple application configurations without hardware changes.
• Balanced on-chip resources: The combination of 466 logic element cells and 6,272 bits of embedded RAM enables compact implementations of control logic, state machines, and small data buffers without external memory.
• High I/O density: 112 programmable I/O pins provide flexible connectivity options for interfacing with sensors, peripherals, and system buses.
• System-level test support: Boundary-scan capability (IEEE 1149.1-compatible as described for the family) simplifies board-level test and debug.
• Standard packaging and supply: 208‑pin BFQFP surface-mount package and 5 V class supply voltage (4.75 V–5.25 V) ease integration on legacy and modern 5 V designs.
• Commercial temperature rating: Rated for 0 °C to 85 °C operation to match typical commercial embedded applications.
