AMD XCS30-4TQ144C

Overview

XCS30-4TQ144C from AMD (formerly Xilinx) is a Spartan-3 FPGA with 30,000 system gates, 144-pin TQFP package, -4 speed grade, and commercial temperature range (0°C to 85°C). It integrates configurable logic blocks, distributed RAM, and dedicated multipliers for digital signal processing in embedded control and interface bridging applications.

For engineers reviewing the XCS30-4TQ144C datasheet, pinout, applications, or equivalent options, key selection factors include I/O count (118 user I/Os), internal RAM (72 Kbits), global clock resources (8), and support for LVCMOS/LVTTL I/O standards in a leaded, RoHS-compliant TQFP package.

Technical Context

The XCS30-4TQ144C implements a fine-grained, SRAM-based architecture with configurable logic blocks (CLBs) arranged in rows and columns, each containing two slices with four LUTs and eight flip-flops. It supports synchronous design with eight global clock networks and DLL-based clock management.

I/O banks are organized into four groups, each supporting independent VCCO voltage (up to 3.3V) and selectable I/O standards including LVCMOS 3.3/2.5/1.8V and LVTTL. Configuration is performed via serial PROM or master serial mode using external bitstream.

Compared with XCS30-5TQ144C and XCS25-4TQ144C, the XCS30-4TQ144C delivers verified timing performance at commercial speed grade -4 with full 30K-gate capacity and 118 I/Os - making it the baseline choice for cost-sensitive, medium-complexity FPGA designs requiring TQFP packaging and proven industrial deployment history.

Availability

XCS30-4TQ144C is available at Aetrix Electronics and suitable for industrial automation, legacy system modernization, and embedded video interface applications requiring stable component supply and long-term obsolescence management.

Supply support for XCS30-4TQ144C includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

AMD acquired Xilinx in 2022 and continues to support legacy Spartan families through its Adaptive SoC and FPGA product organization.

The Spartan-3 family, including XCS30-4TQ144C, was designed for cost-sensitive, high-volume embedded applications requiring flexible logic, moderate I/O count, and rapid time-to-market - especially in industrial control and interface bridging.

FAQ

What is the maximum operating frequency supported by XCS30-4TQ144C?

The XCS30-4TQ144C supports internal logic operation up to 200 MHz under typical commercial conditions. Its -4 speed grade guarantees worst-case path delays compatible with 125 MHz system clocks for fully registered designs, with actual achievable frequency dependent on design topology, placement, and routing. The device includes eight global clock networks optimized for low skew and DLL-assisted deskew.

Does XCS30-4TQ144C support JTAG boundary-scan testing?

Yes, XCS30-4TQ144C supports IEEE 1149.1 JTAG boundary-scan via dedicated pins (TCK, TMS, TDI, TDO) located in the configuration bank. This enables in-circuit verification, interconnect testing, and programming during manufacturing. The JTAG interface operates independently of the configuration mode and remains accessible after configuration.

What power supplies are required for XCS30-4TQ144C operation?

XCS30-4TQ144C requires two primary supplies: 1.2 V ±3% for core logic (VCCINT) and 1.8/2.5/3.3 V for I/O banks (VCCO), configurable per bank. Decoupling capacitors (0.1 µF ceramic + 4.7 µF tantalum per supply) are mandatory near each supply pin. Unused I/O banks must have VCCO tied to a valid voltage or grounded per Xilinx DC and Switching Characteristics documentation.

Can XCS30-4TQ144C be reconfigured in-system?

Yes, XCS30-4TQ144C supports in-system reconfiguration via its slave serial or master serial configuration modes. Using an external processor or PROM, the bitstream can be reloaded without power cycling. The DONE pin confirms successful configuration, and PROGRAM_B initiates a new configuration cycle - enabling field-upgradable logic functionality in deployed systems.

Is XCS30-4TQ144C still in active production?

XCS30-4TQ144C is discontinued by AMD/Xilinx but remains available through authorized distributors and Aetrix Electronics' extended lifecycle program. Aetrix maintains traceable inventory, provides obsolescence notifications, and supports last-time-buy planning for customers transitioning to Spartan-6 or newer families.
