Product details
Overview
XC2S15-5TQ144C from AMD (formerly Xilinx) is a Spartan-II family FPGA with 15,000 system gates, 176 logic cells, 176 configurable logic blocks (CLBs), 144-pin TQFP package, and -5 speed grade (5 ns CLB delay). It targets low-cost, high-volume embedded control and interface bridging applications.
For engineers reviewing the XC2S15-5TQ144C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (118 user I/Os), distributed RAM capacity (176 × 16-bit), global clock routing, LVCMOS/LVTTL I/O support, and configuration via serial PROM or JTAG.
Technical Context
The XC2S15-5TQ144C implements a hierarchical architecture with configurable logic blocks (CLBs), input/output blocks (IOBs), and interconnect resources. Each CLB contains two 4-input function generators, carry logic, and flip-flops for synchronous operation.
It supports in-system configuration through IEEE 1149.1 JTAG boundary-scan and serial master/slave mode using external PROM. I/O banks are independently configurable for 3.3 V or 2.5 V operation with programmable slew rate and drive strength.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Capacity | 15,000 system gates - defines maximum combinational logic density for gate-equivalent synthesis |
| Configurable Logic Blocks | 176 CLBs - each provides dual 4-LUTs + flip-flops, enabling pipelined arithmetic and state machine implementation |
| User I/O Pins | 118 - supports parallel bus interfaces, sensor arrays, and multi-protocol peripheral connectivity |
| Distributed RAM | 176 × 16-bit - usable as shift registers, FIFO buffers, or small lookup tables without block RAM |
| Speed Grade | -5 (5 ns CLB propagation delay) - enables 160 MHz maximum clock frequency for registered logic paths |
| I/O Standards | LVCMOS, LVTTL, PCI - allows direct interfacing with microcontrollers, memory, and legacy peripherals |
Pinout & Package
XC2S15-5TQ144C uses 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 TQFP-144.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCK0–GCK3 | Global Clock Input | Dedicated low-skew routing to all CLBs; required for synchronous timing-critical designs |
| PROGRAM_B | Configuration Initiate | Active-low signal that resets configuration logic and clears internal SRAM before reload |
| DONE | Configuration Status | Open-drain output indicating successful bitstream loading and device readiness |
| TCK/TMS/TDI/TDO | JTAG Boundary-Scan | IEEE 1149.1 compliant test and programming interface; enables in-circuit debugging and ISP |
| IO_LxxN/IO_LxxP | User I/O Bank Pins | Grouped into four I/O banks; voltage and drive strength configured per bank, not per pin |
Key Features
| Feature | Design Value |
|---|---|
| In-System Programmability | Supports reconfiguration via JTAG or serial PROM without removing device from PCB |
| Dedicated Carry Chain | Enables high-speed arithmetic (e.g., counters, adders) with 1-bit propagation delay per stage |
| Three-State Bus Hold | Prevents floating I/O states during tri-state contention; eliminates need for external pull-ups |
| SelectRAM+ Technology | Each CLB's LUT can be configured as 16-bit synchronous RAM or shift register |
| Multi-Voltage I/O Banks | Independent 3.3 V / 2.5 V support per bank enables mixed-voltage system interfacing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA-based logic integration applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC2S25-5TQ144C | 25,000 gates, 256 CLBs, same package and speed grade | Higher gate count supports larger state machines and wider data paths | Choose when design requires >15K gates but must retain identical footprint and timing closure |
| XC3S50A-4VQ100C | Spartan-3A family, 50K gates, 100-pin VQFP, -4 speed grade | Includes embedded multipliers and larger block RAM; no distributed RAM per CLB | Prefer for math-intensive tasks or when migrating to newer architecture with longer lifecycle support |
Compared with XC2S15-5TQ144C, XC2S25-5TQ144C offers scalable logic density within identical mechanical and timing constraints, while XC3S50A-4VQ100C trades distributed RAM flexibility for enhanced DSP capability and updated process technology-requiring PCB and timing redesign.

FAQ
What is the maximum operating frequency of the XC2S15-5TQ144C?
The XC2S15-5TQ144C has a -5 speed grade specifying 5 ns CLB propagation delay, enabling up to 160 MHz for fully registered logic paths. Actual system frequency depends on routing, fanout, and I/O timing constraints. The XC2S15-5TQ144C does not include PLLs, so clock multiplication requires external circuitry or higher-frequency input sources.
Does the XC2S15-5TQ144C support JTAG boundary-scan testing?
Yes, the XC2S15-5TQ144C fully complies with IEEE 1149.1 JTAG standards. Its TCK, TMS, TDI, and TDO pins enable in-circuit testing, programming, and debug visibility. This capability is integral to the XC2S15-5TQ144C's configuration and validation workflow in production and field service environments.
Can the XC2S15-5TQ144C be reconfigured in-system?
Yes, the XC2S15-5TQ144C supports in-system programmability via JTAG or serial master mode using an external PROM. Configuration bitstream reload preserves pin states during reconfiguration, making the XC2S15-5TQ144C suitable for field-upgradable logic in deployed systems without hardware intervention.
What I/O voltage levels does the XC2S15-5TQ144C support?
The XC2S15-5TQ144C supports 3.3 V and 2.5 V I/O standards across four independent banks. Each bank's VCCO is externally supplied, allowing mixed-voltage operation-for example, interfacing with 3.3 V microcontrollers and 2.5 V ADCs simultaneously. The XC2S15-5TQ144C does not support 1.8 V or 1.5 V I/O natively.
Is the XC2S15-5TQ144C still in active production?
The XC2S15-5TQ144C is obsolete per AMD/Xilinx product discontinuation notices, but Aetrix Electronics maintains verified legacy inventory with full traceability. Engineering samples and production lots of the XC2S15-5TQ144C remain available under controlled distribution for legacy system maintenance and long-lifecycle programs.
