Description and Introduction

XC4000XLA/XV Field Programmable Gate Arrays The **XC4085XLA** is a Field Programmable Gate Array (FPGA) manufactured by **Xilinx**. Below are its specifications, descriptions, and features based on available data:  

### **Specifications:**  
- **Family:** XC4000 Series  
- **Logic Cells:** ~85,000 gates (approximate equivalent)  
- **Configuration:** SRAM-based, reprogrammable  
- **Package:** Large Array (LA) package  
- **Operating Voltage:** 5V (typical for XC4000 series)  
- **I/O Pins:** Varies by package (exact count depends on specific variant)  
- **Speed Grade:** Available in multiple speed grades (e.g., -4, -5)  
- **On-Chip Memory:** Distributed RAM and block RAM (varies by configuration)  

### **Descriptions:**  
- The **XC4085XLA** is a high-capacity FPGA from Xilinx's **XC4000** family, designed for complex digital logic applications.  
- It supports **in-system reprogrammability**, making it suitable for prototyping and flexible designs.  
- Features **programmable logic blocks (CLBs)**, **interconnect resources**, and **I/O blocks (IOBs)** for customizable digital circuits.  

### **Features:**  
- **High Gate Density:** Suitable for large-scale designs (~85K gates).  
- **Flexible Routing:** Hierarchical interconnect structure for efficient signal routing.  
- **SRAM-Based Configuration:** Requires external configuration memory (e.g., PROM).  
- **Wide Operating Conditions:** Supports industrial temperature ranges.  
- **JTAG Support:** For boundary scan testing and programming.  
- **Compatibility:** Works with Xilinx development tools (e.g., XACT, ISE for legacy designs).  

For exact pinout, timing, and package details, refer to the official **Xilinx XC4000 datasheet** or user guide.

Application Scenarios & Design Considerations

XC4000XLA/XV Field Programmable Gate Arrays

Alternative Part Number

  • XC4085XL --: Same XC4000XL family FPGA with identical 4085 logic density, differing only in the XLA low-power variant designation, making it a close functional substitute.
  • XC4085XLA-09 --: Speed-grade variant of the same XLA device; usable when timing margin allows and the exact base part is unavailable.
  • XC4010XL --: Larger XC4000XL family device that can often replace the 4085XLA in designs with spare logic capacity, though pinout and package must be verified.
