XC4028EX-4HQ208C

The XC4028EX-4HQ208C is a Field Programmable Gate Array (FPGA) IC from AMD's XC4000E/X family. It delivers programmable digital logic resources and a substantial I/O complement in a 208-pin exposed-pad package intended for surface-mount assembly.

This device is designed for designs that require a balance of logic capacity, on-chip memory, and I/O density while operating from a standard 5 V supply in commercial temperature environments.

Key Features

• Logic Capacity  Approximately 2,432 logic elements supported by 1,024 CLBs, enabling implementation of custom digital functions and combinational/sequential logic networks.
• Embedded Memory  Approximately 32 Kbits of on-chip RAM (32,768 bits) for small lookup tables, buffering, or state storage.
• I/O  160 general-purpose I/O pins to interface with peripherals, buses, and external logic.
• Gate Count  28,000 equivalent gates, providing a clear metric for overall logic scale.
• Package and Mounting  208-BFQFP with exposed pad (supplier package listed as 208-PQFP, 28×28); surface-mount mounting type for PCB assembly.
• Power  Operates from a single supply in the 4.75 V to 5.25 V range for straightforward integration with standard 5 V systems.
• Operating Range  Commercial-grade operation from 0 °C to 85 °C for typical ambient conditions.
• Environmental Compliance  RoHS compliant for alignment with common environmental requirements.

Typical Applications

• Prototyping & Development  Fast evaluation of custom logic and proof-of-concept designs using on-chip logic and memory resources.
• Peripheral and Interface Bridging  Implement glue logic, protocol adaptation, and parallel interfacing using the device's 160 I/O pins.
• Control Logic  Implement finite state machines and control sequencing where compact embedded memory and moderate gate count are sufficient.

Unique Advantages

• Balanced Logic and Memory: The combination of ~2,432 logic elements and ~32 Kbits of embedded RAM supports compact digital subsystems without external memory.
• High I/O Density: 160 I/O pins enable extensive external connectivity, reducing the need for additional interface components.
• Standard 5 V Supply: Operates from 4.75 V to 5.25 V, simplifying power design for legacy and common systems.
• Surface-Mount Exposed-Pad Package: 208-BFQFP with exposed pad offers thermal and mounting advantages for PCB-level integration.
• Regulatory Alignment: RoHS compliance supports inclusion in environmentally conscious product designs.
