XC3S400-4TQG144C

The XC3S400-4TQG144C is a Spartan®-3 field programmable gate array (FPGA) supplied in a 144-pin low-profile quad flat package. It provides a balance of configurable logic, embedded memory and I/O capacity for commercial electronic designs and development projects.

With 8,064 logic elements distributed across 896 CLBs, approximately 0.295 Mbits of on-chip RAM and 97 I/O pins, this device targets applications that require moderate gate density, flexible I/O and low-voltage core operation.

Key Features

• Core Logic — 896 CLBs delivering 8,064 logic elements for implementing custom digital logic and state machines.
• Embedded Memory — Approximately 0.295 Mbits (294,912 bits) of on-chip RAM to support buffering, lookup tables and small data stores directly in the FPGA fabric.
• I/O Capacity — 97 user I/O pins for interfacing with peripherals, sensors and external logic devices.
• Gate Count — 400,000 gates to describe relative implementation scale for integration planning and partitioning.
• Power — Core voltage operation in the 1.14 V to 1.26 V range to match low-voltage system designs.
• Package & Mounting — Supplied in a 144-LQFP (supplier package: 144-TQFP, 20×20) configured for surface-mount assembly.
• Operating Range & Grade — Commercial grade device rated for 0 °C to 85 °C operating temperature.
• Environmental Compliance — RoHS-compliant construction for regulatory alignment in commercial products.

Typical Applications

• Prototyping and Development — Used on development boards and evaluation platforms where configurable logic and moderate I/O density enable rapid design iteration.
• Embedded Control — Implements custom control logic, state machines and peripheral management in commercial electronic devices.
• Interface Bridging — Acts as glue logic for protocol conversion and signal aggregation between discrete peripherals and host processors.
• Communication Prototypes — Suitable for early-stage communication and data-handling designs that require on-chip memory for buffering.

Unique Advantages

• Balanced Logic Density: 8,064 logic elements and 896 CLBs provide a midrange capacity for integrating multiple functions without excessive board-level complexity.
• On-Chip Memory: Approximately 0.295 Mbits of embedded RAM reduces reliance on external memory for small buffers and lookup tables.
• Ample I/O: 97 I/O pins enable direct connections to a variety of peripherals, reducing the need for additional interface components.
• Compact Surface-Mount Package: 144-LQFP (144-TQFP, 20×20) supports compact PCB layouts and standard assembly processes.
• Low-Voltage Core Operation: Core supply from 1.14 V to 1.26 V aligns with low-voltage system architectures.
• RoHS Compliance: Environmentally compliant construction simplifies regulatory considerations for commercial products.
