概要

Description

XC3S400AN-4FTG256C is a Xilinx Spartan-3S CPLD device. It offers about 400 logic elements (LEs) for glue logic, small state machines, and simple control/data-path tasks. The device is packaged in a 256-pin Fine-Pitch Grid Array (FTG256) with a C variant, and has speed grade -4 for faster I/O timing. It supports multiple I/O banks and standard CPLD features such as programmable logic blocks, flip-flops, and dedicated I/O resources, enabling implementations like decoders, counters, interfacing logic, and protocol bridges. Programming and configuration are supported via the device’s JTAG/CONFIG interfaces. This mid-density CPLD is aimed at low-to-medium complexity digital logic in cost-sensitive, size-constrained designs and is suitable for glue logic, simple controllers, and peripheral interfaces in consumer, industrial, or embedded applications.

Features

XC3S400AN-4FTG256C is a Spartan-3 FPGA with:
- About 400K system gates (approx. source-density figure for XC3S400 series)
- Speed grade -4 (faster variant)
- FG256C: 256-pin FineLine BGA package
- LUT-based logic slices (CFG/slice with flip-flop)
- On-chip RAM blocks plus distributed RAM
- DSP/multiplier resources for signal processing
- Clock management: PLLs/DLLs for flexible timing
- Flexible I/O across multiple banks (LVTTL/3.3V I/O; various I/O standards)
- In-system reconfigurability and standard FPGA fabric for logic, memory, and DSP
Note: exact I/O counts and RAM sizes vary by device, so consult the datasheet for precise resources.
