XC3S400-5FT256C

The XC3S400-5FT256C is a Spartan®-3 Field Programmable Gate Array (FPGA) IC manufactured by AMD. It provides a balance of on-chip logic, embedded memory and I/O resources in a 256-ball LFBGA package for commercial-grade applications.

Key device resources include 8,064 logic elements, approximately 0.295 Mbits of embedded RAM, 173 I/O pins and an internal gate equivalence of 400,000 gates, with a specified supply range of 1.14 V to 1.26 V and an operating temperature range of 0 °C to 85 °C.

Key Features

• Core Logic 8,064 logic elements provide programmable combinational and sequential resources for custom digital logic implementations.
• Embedded Memory Approximately 0.295 Mbits of on-chip RAM to support buffering, state storage and small on-chip data structures.
• I/O and Gate Count 173 user I/O pins and an equivalent of 400,000 gates enable broad interfacing and moderate-scale logic integration.
• Power Specified supply voltage range of 1.14 V to 1.26 V for core operation.
• Package and Mounting 256-LBGA package (supplier device package: 256-FTBGA, 17×17) with surface-mount mounting type for compact PCB layouts.
• Temperature and Grade Commercial-grade device rated for 0 °C to 85 °C operation.
• Environmental Compliance RoHS compliant.

Unique Advantages

• High logic capacity: 8,064 logic elements enable implementation of moderate-complexity digital functions without external logic.
• On-chip RAM: Approximately 0.295 Mbits of embedded memory reduces the need for external memory for small buffering and state storage.
• Generous I/O count: 173 I/O pins support multiple peripheral interfaces and board-level connectivity options.
• Compact BGA footprint: 256-LBGA (17×17) package supports dense PCB designs and surface-mount assembly.
• Low-voltage core operation: Narrow supply range (1.14 V to 1.26 V) supports stable core power delivery designs.
• Commercial availability and compliance: Commercial-grade rating and RoHS compliance simplify procurement and regulatory requirements for consumer and industrial applications within the specified temperature range.
