AMD XC2S30-5TQ144C

Overview

XC2S30-5TQ144C from AMD (formerly Xilinx) is a Spartan-II family FPGA with 30,000 system gates, 144-pin TQFP package, 5 ns logic delay, and embedded RAM blocks. It serves as a reconfigurable logic fabric for digital control, interface bridging, and real-time signal processing in industrial I/O modules.

For engineers reviewing the XC2S30-5TQ144C datasheet, pinout, applications, or equivalent options, key selection factors include logic capacity, I/O count (117 user I/Os), operating voltage (2.5 V core / 3.3 V I/O), configuration mode (JTAG/Slave Serial), and temperature grade (commercial, 0°C to 85°C).

Technical Context

The XC2S30-5TQ144C implements configurable logic blocks (CLBs) with four-input LUTs and flip-flops, distributed RAM (1728 bits), and dedicated carry logic for arithmetic. It supports SelectI/O standards including LVTTL, LVCMOS, and PCI.

Configuration is performed via JTAG boundary-scan or serial PROM; internal configuration memory is volatile and requires external bitstream loading at power-up. The device uses 2.5 V core supply with separate 3.3 V I/O supply rails.

Key Specifications

Pinout & Package

XC2S30-5TQ144C is housed in a 144-pin Thin Quad Flat Package (TQFP) with 0.5 mm pitch, 20 mm × 20 mm body size, and exposed thermal pad (non-electrical). Pin assignment follows Xilinx Spartan-II pinout standard for this package variant.

Availability

XC2S30-5TQ144C is available at Aetrix Electronics and suitable for industrial automation, legacy system modernization, and embedded control applications requiring stable component supply across extended production lifecycles.

Supply support for XC2S30-5TQ144C 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 now oversees the Spartan FPGA product line. Xilinx originally developed the Spartan series as cost-optimized, high-volume FPGAs for non-ASIC digital logic replacement.

The Spartan-II family, including XC2S30-5TQ144C, was engineered for mainstream industrial and communications applications where gate density, I/O flexibility, and commercial-temperature operation were prioritized over ultra-high speed or advanced features.

FAQ

What is the configuration method supported by XC2S30-5TQ144C?

The XC2S30-5TQ144C supports JTAG boundary-scan configuration and Slave Serial mode using an external PROM or microcontroller. It does not include on-chip non-volatile configuration memory, so bitstream loading occurs at every power-on. Configuration time depends on PROM size and clock frequency, typically under 100 ms for standard bitstreams. The XC2S30-5TQ144C requires external configuration circuitry and cannot operate without a valid bitstream.

Does XC2S30-5TQ144C support hot-swap I/O operation?

No, XC2S30-5TQ144C does not support hot-swap I/O. Its I/O pins are not designed for live insertion or removal under power. The device lacks bus-hold circuitry on all pins by default and requires proper power sequencing (VCCINT before VCCO) to avoid latch-up. Safe operation mandates that power supplies be stable and within specification before asserting configuration signals. This applies specifically to the XC2S30-5TQ144C and its commercial-grade thermal envelope.

What is the maximum operating frequency achievable with XC2S30-5TQ144C?

The XC2S30-5TQ144C speed grade -5 specifies a 5 ns CLB propagation delay, enabling synchronous system clock frequencies up to approximately 160 MHz in well-constrained designs. Actual maximum frequency depends on routing congestion, logic depth, and I/O timing closure. Critical paths involving carry chains or dedicated multipliers (not present in Spartan-II) may achieve higher local rates, but the XC2S30-5TQ144C has no embedded multipliers - limiting arithmetic throughput compared to later families.

Can XC2S30-5TQ144C be used in automotive applications?

No, XC2S30-5TQ144C is rated for commercial temperature range (0°C to 85°C) and is not qualified for automotive use. It lacks AEC-Q100 qualification, extended temperature screening, and automotive-grade reliability documentation. While some designers have deployed it in non-safety-critical aftermarket devices, the XC2S30-5TQ144C is not recommended or supported for under-hood or ADAS-related applications where ambient temperatures exceed 85°C or functional safety compliance is required.

Is there a pin-compatible replacement for XC2S30-5TQ144C with higher density?

Yes, XC2S50-5TQ144C is a pin-compatible replacement offering 50,000 system gates in the same 144-pin TQFP package. It shares identical pinout, power requirements, and configuration interface with XC2S30-5TQ144C, allowing drop-in logic upgrades without PCB changes. However, the XC2S50-5TQ144C consumes more dynamic power and may require updated thermal management if operating at maximum utilization.
