AMD XCS30XL-4TQG144I

Overview

XCS30XL-4TQG144I from AMD (formerly Xilinx) is a Spartan-XL family FPGA with 30,000 system gates, 144-pin TQFP package, -4 speed grade, and industrial temperature range (–40°C to +100°C). It integrates configurable logic blocks, I/O banks with 3.3V/5V tolerance, and dedicated carry logic for arithmetic functions - deployed in legacy industrial control and test equipment.

For engineers reviewing the XCS30XL-4TQG144I datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O voltage support, timing performance at industrial temperature, and availability of legacy configuration PROMs.

Technical Context

The XCS30XL-4TQG144I implements a fine-grained architecture with 1,152 configurable logic blocks (CLBs), each containing two 3-input LUTs and flip-flops. It supports in-system programmability via JTAG boundary-scan and serial PROM configuration.

It features 118 user I/O pins organized in four banks, each independently configurable for 3.3V or 5V signaling, with programmable slew rate and pull-up resistors. No internal PLL or DLL; clock distribution relies on global routing resources.

XCS30XL-4TQG144I is available at Aetrix Electronics and suitable for industrial automation, avionics maintenance systems, and semiconductor test equipment requiring stable component supply across extended product lifecycles.

Supply support for XCS30XL-4TQG144I 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, inheriting its FPGA portfolio including the Spartan family. AMD focuses on adaptive computing solutions for data center, AI, and industrial markets.

The Spartan-XL family was designed for cost-sensitive, high-reliability applications where long-term availability and mixed-voltage interfacing are critical - especially in industrial control and test instrumentation.

FAQ

What is the maximum operating frequency supported by the XCS30XL-4TQG144I?

The XCS30XL-4TQG144I has a -4 speed grade specifying a 10 ns maximum input-to-output delay for critical paths. Achievable system clock frequencies depend on design topology but typically range up to 80 MHz for register-to-register paths in well-constrained implementations. The device lacks internal PLLs, so clock multiplication must be implemented externally or via logic-based techniques.

Does the XCS30XL-4TQG144I support JTAG boundary-scan testing?

Yes, the XCS30XL-4TQG144I fully supports IEEE 1149.1 JTAG boundary-scan for programming, debugging, and board-level interconnect testing. Pins TCK, TMS, TDI, and TDO are dedicated for this function and operate at VCCO voltage levels, enabling test access even during partial power-up sequences.

Can the XCS30XL-4TQG144I interface directly with both 3.3V and 5V devices?

Yes, the XCS30XL-4TQG144I supports mixed-voltage operation through four independent I/O banks, each with its own VCCO supply. This allows simultaneous connection to 3.3V microcontrollers and 5V sensors or legacy peripherals without external level shifters - a key capability confirmed in the Spartan-XL DC and switching characteristics datasheet.

Is the XCS30XL-4TQG144I still in production or considered obsolete?

The XCS30XL-4TQG144I is no longer in active production by AMD/Xilinx but remains available through authorized legacy component distributors and Aetrix Electronics' extended-life inventory program. It is supported under AMD's Obsolescence Management Policy with last-time-buy notifications and controlled distribution for qualified industrial and aerospace programs.

What configuration memory is compatible with the XCS30XL-4TQG144I?

The XCS30XL-4TQG144I supports master serial configuration using industry-standard Xilinx-compatible PROMs including XC18V02, XC18V04, and XC17S30. Configuration bitstreams are loaded on power-up via dedicated PROGRAM_B and INIT_B pins, with support for both serial and parallel PROM interfaces depending on mode pin settings.
