XC4005XL-3PQ208C

The XC4005XL-3PQ208C is a field programmable gate array (FPGA) device in the XC4000E/X family, supplied in a 208-pin BFQFP package. It offers a compact, surface-mount programmable-logic solution with on-chip RAM, a moderate logic element count, and a broad I/O complement suitable for commercial-temperature digital designs.

Key Features

• Core Logic — 196 CLBs and 466 logic element cells provide programmable logic resources for implementing custom digital functions.
• Embedded Memory — 6,272 bits of on-chip RAM for small data buffers, state machines, and lookup tables.
• I/O Capacity — 112 I/O pins to interface with peripherals, sensors, or supporting logic in system designs.
• Logic Density — Approximate equivalent of 5,000 gates for integrating glue logic, small datapaths, and control functions.
• Power — Operates from a 3 V to 3.6 V supply range to match common commercial power rails.
• Package & Mounting — 208-BFQFP (supplier device package: 208-PQFP, 28×28 mm) in a surface-mount form factor for PCB assembly.
• Temperature & Grade — Commercial grade with an operating temperature range of 0 °C to 85 °C.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Custom digital logic and prototyping — Use the 466 logic elements and 196 CLBs to implement and iterate small to medium-scale digital designs and proofs of concept.
• Glue logic and system control — 112 I/O pins and ~5,000 gates enable integration of custom interfaces, control state machines, and signal conditioning between subsystems.
• Embedded buffering and lookup functions — 6,272 bits of on-chip RAM support small FIFOs, register files, and lookup tables for control and data-path tasks.

Unique Advantages

• Balanced resource set: A combination of CLBs, logic elements, and on-chip RAM provides flexibility for diverse small-to-medium logic implementations without overprovisioning.
• Robust I/O count: 112 I/Os allow direct interfacing to a wide range of peripherals and external logic, reducing the need for additional interface chips.
• Standard commercial power range: 3.0 V–3.6 V operation fits common board power rails, simplifying power supply design.
• Surface-mount 208-pin package: The 208-BFQFP/208-PQFP (28×28) package supports standard SMT assembly and dense PCB layouts.
• RoHS compliant: Meets environmental compliance requirements for modern electronic manufacturing processes.
