The XC4028XL-3HQ240I is an AMD XC4000E/X family Field Programmable Gate Array (FPGA) IC providing reconfigurable digital logic in a surface-mount 240-BFQFP package with exposed pad. It offers 2,432 logic elements, approximately 0.033 Mbits of on-chip RAM, and 193 I/O pins, making it suitable for industrial designs that require configurable logic, significant I/O density, and operation across a wide temperature range.

Key Features

• Core Logic 2,432 logic elements and approximately 28,000 gates enable implementation of custom digital functions and moderate-complexity logic networks.
• On-chip Memory 32,768 bits of embedded RAM (approximately 0.033 Mbits) for local storage, buffering, and state machines.
• I/O Density 193 general-purpose I/O pins provide flexible interfacing to peripherals, sensors, and external logic.
• Power Operates from a 3.0 V to 3.6 V supply range, allowing integration with 3.3 V system domains.
• Package and Mounting 240-BFQFP package with exposed pad (supplier device package listed as 240-PQFP, 32×32) in a surface-mount form factor for PCB assembly.
• Temperature and Grade Industrial-grade device rated for operation from −40 °C to 100 °C, addressing demanding ambient conditions.
• Environmental Compliance RoHS compliant.

Typical Applications

• Industrial Control — Reconfigurable logic and 193 I/Os support control, monitoring, and interface tasks within industrial systems operating across −40 °C to 100 °C.
• Embedded Systems — On-chip RAM and 2,432 logic elements enable custom datapaths, glue logic, and protocol handling in embedded designs.
• Interface and Peripheral Bridging — High I/O count allows the device to act as an interface bridge between multiple buses or peripherals.

Unique Advantages

• Balanced Logic Capacity: 2,432 logic elements provide a practical balance of density for moderate-complexity designs without excessive board-level integration.
