XC3S400AN-5FGG400C

The XC3S400AN-5FGG400C is a Spartan®-3AN Field Programmable Gate Array (FPGA) IC from AMD in a 400-BGA package. It delivers a combination of programmable logic, embedded memory, and a high I/O count for commercial-grade FPGA applications.

With 896 configurable logic blocks (CLBs) totaling 8,064 logic elements and approximately 0.37 Mbits of on-chip RAM, this device is targeted at commercial designs that require configurable digital logic in a compact surface-mount 400-FBGA (21×21) package.

Key Features

• Core Logic  896 configurable logic blocks (CLBs) providing 8,064 logic elements for implementing custom digital logic functions.
• Embedded Memory  Approximately 0.37 Mbits of on-chip RAM (368,640 bits) for local buffering and state storage.
• I/O and Gate Count  311 user I/O pins and an approximate 400,000-gate equivalent capacity to support diverse interfacing requirements.
• Package and Mounting  400-BGA (supplier device package: 400-FBGA, 21×21), surface-mount for high pin density in a compact footprint.
• Power  Nominal supply voltage range of 1.14 V to 1.26 V to match targeted system power architectures.
• Operating Conditions  Commercial grade device with an operating temperature range of 0 °C to 85 °C.
• Compliance  RoHS compliant.

Unique Advantages

• Substantial programmable logic capacity: 8,064 logic elements and 896 CLBs support moderately complex custom logic implementations without external logic devices.
• On-chip memory integration: Approximately 0.37 Mbits of embedded RAM reduces dependence on external memory for many buffering and control tasks.
• High I/O availability: 311 I/O pins provide flexibility for connecting to multiple peripherals, sensors, and board-level interfaces.
• High-density packaging: 400-BGA (21×21) delivers a compact, high-pin-count solution suitable for space-constrained PCBs.
• Predictable power window: A defined supply voltage range (1.14 V–1.26 V) simplifies power supply design and validation.
• Commercial temperature suitability: Rated for 0 °C to 85 °C operation for general commercial environments.
