The XC4028XLA-09HQ208C is a Field-Programmable Gate Array (FPGA) belonging to the Xilinx XC4000XLA family. This series is characterized by its low-voltage operation, making it suitable for applications where power efficiency is a key requirement. The device is packaged in a 208-pin HQFP (Quad Flat Pack) package, which provides a balance between pin count and ease of handling.

Applications:

• Mobile communication devices
• Portable instrumentation
• Low-power industrial control systems
• Handheld computing devices
• Battery-operated medical equipment

Features

• Low-Voltage Operation: Designed to operate at a lower voltage, typically 3.3V, which significantly reduces power consumption.
• Configurable Logic Blocks (CLBs): The XC4028XLA-09HQ208C contains an array of CLBs that can be configured to implement a wide range of digital logic functions.
• Input/Output Blocks (IOBs): The device features programmable IOBs that provide an interface between the internal logic and external pins.
• Interconnect Resources: A flexible interconnect structure enables signals to be routed between CLBs and IOBs efficiently.
• On-Chip RAM: Includes dedicated block RAM for storing data and implementing memory functions.
• Operating Voltage: Operates at 3.3V.
