XC3S1600E-4FG320I

The XC3S1600E-4FG320I is a Spartan®-3E Field Programmable Gate Array (FPGA) IC designed for industrial applications requiring substantial programmable logic and on-chip memory. Its architecture delivers a balance of logic capacity, embedded RAM and I/O density in a compact 320‑ball BGA package for surface-mount assembly.

With 33,192 logic elements, approximately 0.66 Mbits of embedded memory and 250 user I/Os, this device targets designs that need mid-range gate capacity and flexible I/O integration across a wide operating temperature range.

Key Features

• Core Logic — 33,192 logic elements and 3,688 CLBs provide programmable logic capacity to implement custom digital designs and state machines.
• Embedded Memory — Total on-chip RAM of 663,552 bits (approximately 0.66 Mbits) for data buffering, FIFOs and small lookup-table storage.
• I/O and Gate Count — 250 user I/Os and an equivalent of 1,600,000 gates to support parallel interfaces and complex glue-logic functions.
• Power and Supply — Core voltage supply range of 1.14 V to 1.26 V to match system power-rail constraints.
• Package and Mounting — 320‑BGA (supplier package: 320‑FBGA 19×19) in a surface-mount form factor for compact PCB layouts and high-density routing.
• Industrial Temperature Range — Rated for operation from −40 °C to 100 °C to support industrial and ruggedized environments.
• Compliance — RoHS compliant for alignment with common environmental requirements.

Typical Applications

• Industrial Control — Implement custom control logic, timing-critical sequencing and interface bridging while taking advantage of the industrial temperature rating and abundant I/O.
• Embedded Systems — Integrate system glue logic, protocol handling and small data buffering using the device’s logic capacity and embedded RAM.
• Custom Peripherals and I/O Expansion — Use the 250 I/Os to create tailored peripheral interfaces, sensor aggregation or bus translation functions.
• Prototyping and Small-Scale Production — Apply the mid-range logic and memory resources for proof-of-concept designs or moderate-volume deployments requiring surface-mount packaging.

Unique Advantages

• Substantial Logic Density: 33,192 logic elements enable implementation of complex state machines and custom datapaths without external CPLDs or ASICs.
• Embedded Memory for Local Storage: Approximately 0.66 Mbits of on-chip RAM reduces dependence on external memory for buffering and small lookup tables.
• High I/O Count: 250 user I/Os simplify board-level integration by supporting multiple parallel interfaces and peripherals directly on-chip.
• Industrial Temperature Support: Operation from −40 °C to 100 °C provides wider environmental tolerance for factory, outdoor or harsh-condition deployments.
• Compact, High-Density Package: 320‑BGA (19×19) offers a small PCB footprint with routing options suitable for space-constrained designs.
• Regulatory Alignment: RoHS compliance supports designs targeting markets with environmental material restrictions.
