XC3S100E-4VQG100C

The XC3S100E-4VQG100C is a Spartan®-3E series FPGA IC from AMD designed for programmable logic applications. It integrates configurable logic, on-chip RAM, and a moderate I/O count in a 100-pin TQFP package, targeted at commercial-grade embedded and digital designs that require compact, reprogrammable logic resources.

Key on-chip resources include 240 CLBs (providing 2,160 logic elements), approximately 73,728 bits of embedded RAM, and support for up to 66 I/O pins. The device operates from a supply voltage range of 1.14 V to 1.26 V and is rated for commercial temperature operation from 0°C to 85°C.

Key Features

• Core Logic 240 configurable logic blocks (CLBs) delivering 2,160 logic elements for implementing custom digital logic and state machines.
• On-Chip Memory Approximately 73,728 bits of embedded RAM to support buffering, small lookup tables, and local data storage.
• I/O Capacity 66 general-purpose I/O pins suitable for interfacing with sensors, peripherals, and external logic.
• Gate Density 100,000 logic gates providing a compact logic fabric for moderate-complexity applications.
• Power and Temperature Operates from 1.14 V to 1.26 V and rated for commercial temperature range from 0°C to 85°C.
• Package and Mounting 100-TQFP (100-VQFP, 14×14 mm) surface-mount package for compact PCB implementations and established assembly processes.
• Environmental RoHS compliant.

Typical Applications

• Embedded Logic Integration Implement glue logic, protocol translators, or custom control functions where reprogrammability and moderate logic density are required.
• Digital Prototyping Use the device for hardware validation and iterative design development that benefits from on-chip reconfiguration and local RAM.
• Peripheral and Interface Control Manage multiple peripheral interfaces or coordinate I/O-intensive tasks using the device's 66 available I/O pins.

Unique Advantages

• Balanced Logic and Memory Resources: 240 CLBs with 2,160 logic elements alongside 73,728 bits of RAM provide a practical mix of logic and storage for mid-range designs.
