What Is the XC4085XLA-09BG560I? Key Product Overview

The XC4085XLA-09BG560I belongs to Xilinx’s XC4000XLA/XV series — one of the most mature and widely deployed Xilinx FPGA families in the industry. The “XLA” designation indicates the enhanced speed and low-voltage variant of the XC4000 architecture, operating at 3.3V with 0.35µm CMOS technology. The “-09” speed grade denotes a maximum system clock frequency of 227 MHz, while the “BG560I” suffix specifies the 560-pin Plastic Ball Grid Array (MBGA) package in industrial temperature range (–40°C to +100°C).

This part is manufactured by AMD (formerly Xilinx) and is currently available through Rochester Electronics, a licensed distributor specializing in lifecycle and end-of-life semiconductor solutions.

XC4085XLA-09BG560I Architecture and Key Features

#### Configurable Logic Blocks (CLBs)

The XC4000XLA architecture is built around a regular, flexible array of Configurable Logic Blocks (CLBs). Each CLB contains look-up tables (LUTs), flip-flops, and carry logic that can be configured to implement virtually any combinational or sequential logic function. With 7,448 logic cells, the XC4085XLA-09BG560I supports highly complex designs without the need for a custom ASIC.

#### Routing Architecture and Interconnect Resources

Xilinx designed the XC4000XLA family with a rich hierarchy of routing resources including single-length, double-length, and long lines, as well as dedicated carry chains and direct connections between adjacent CLBs. This architecture gives the XC4085XLA-09BG560I the routing flexibility to accommodate the most demanding interconnect patterns with minimal timing penalties.

#### Programmable Input/Output Blocks (IOBs)

The device features 448 user-accessible I/O pins, each controlled by a programmable Input/Output Block (IOB). Each IOB supports:

• Programmable input delay compensation
• TTL and CMOS I/O standards
• Optional pull-up and pull-down resistors
• Output slew rate control

#### Configuration Modes

The XC4085XLA-09BG560I supports multiple configuration loading methods, giving system designers maximum flexibility:

#### Reprogrammability and Dynamic Reconfiguration

One of the defining advantages of the XC4085XLA-09BG560I is that it can be reprogrammed an unlimited number of times. The SRAM-based configuration memory allows engineers to update hardware in the field without board replacement, making this FPGA ideal for:

• Iterative prototyping and hardware development
• Systems requiring runtime hardware updates
• Multi-function devices that switch operating modes dynamically
