XC4VLX15-12FFG668C

The XC4VLX15-12FFG668C is a Virtex®-4 LX Field Programmable Gate Array (FPGA) from AMD. It delivers a balanced combination of programmable logic, on-chip memory, and I/O capacity in a 668-ball FCBGA package for surface-mount PCB integration.

Key on-chip resources include 1,536 CLBs (13,824 logic elements), approximately 0.885 Mbits of embedded memory, and up to 320 I/O pins. Electrical and environmental limits are defined by a core supply range of 1.14 V to 1.26 V and a commercial operating temperature range of 0 °C to 85 °C; the device is RoHS compliant.

Key Features

• Core Architecture  Virtex‑4 LX family FPGA architecture in the XC4VLX15‑12FFG668C configuration.
• Logic Capacity  1,536 CLBs providing 13,824 logic elements for implementing custom digital logic and state machines.
• On‑Chip Memory  Approximately 0.885 Mbits of embedded RAM to support buffering, lookup tables, and small data stores.
• High Pin Count I/O  320 I/O pins to support multiple external interfaces and parallel I/O requirements.
• Power Supply  Core voltage supply specified from 1.14 V to 1.26 V to match system power budgeting and sequencing.
• Package & Mounting  668‑ball FCBGA (27 × 27) package, surface‑mount mounting type, optimized for compact board layouts.
• Commercial Grade & Temperature Range  Commercial grade device rated for operation from 0 °C to 85 °C.

Unique Advantages

• Significant programmable logic density: 1,536 CLBs and 13,824 logic elements enable complex logic implementation without external ASICs.
• On‑chip memory capacity: Approximately 0.885 Mbits of embedded RAM reduces dependency on external memory for moderate buffering and lookup tasks.
• Generous I/O count: 320 I/O pins allow support for parallel interfaces and multiple peripheral connections directly from the FPGA.
• Compact FCBGA packaging: 668‑ball FCBGA (27 × 27) provides a high‑density integration option for space‑constrained boards.
• Defined power and thermal limits: Clear supply voltage range (1.14 V–1.26 V) and commercial temperature rating simplify system design and validation.
• RoHS compliance: Meets common lead‑free manufacturing and regulatory requirements.
