Product details
Overview
XC2S50-5TQG144C from AMD (formerly Xilinx) is a Spartan-II family FPGA with 50,000 system gates, 144-pin TQFP package, 5 ns logic delay, and embedded RAM blocks. It serves as a reconfigurable logic fabric for digital control and interface bridging in industrial I/O modules.
For engineers reviewing the XC2S50-5TQG144C datasheet, pinout, applications, or equivalent options, key selection factors include logic density, I/O count (117 user I/Os), supply voltage (2.5 V core / 3.3 V I/O), configuration mode (Slave Serial, SelectMAP), and temperature grade (Commercial, 0°C to 85°C).
Technical Context
The XC2S50-5TQG144C implements configurable logic blocks (CLBs) with four-input LUTs and flip-flops, distributed RAM (176 Kbits total), and dedicated carry logic for arithmetic. It supports JTAG boundary-scan (IEEE 1149.1) and in-system programmability via serial PROM or microprocessor interface.
Configuration is performed through Slave Serial or SelectMAP modes using external PROM or host processor; no internal non-volatile memory is present. The device requires external configuration memory and power-on initialization sequence compliant with Xilinx Spartan-II specification.
Key Specifications

Pinout & Package
XC2S50-5TQG144C is housed in a 144-pin Thin Quad Flat Pack (TQFP) with 0.5 mm pitch, 20 mm × 20 mm body size, and exposed thermal pad (non-electrical). Pinout conforms to Xilinx Spartan-II pin assignment specification DS001 (v2.5).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G1 | VCCINT | 2.5 V core power supply input - must be decoupled locally |
| P2 | VCCO_0 | 3.3 V I/O bank 0 power - sets output voltage level for pins in Bank 0 |
| T14 | TCK | JTAG test clock input - required for boundary-scan and programming |
| R13 | TMS | JTAG test mode select - controls TAP controller state transitions |
| R14 | TDO | JTAG test data output - serial output during boundary-scan or configuration readback |
| P13 | TDI | JTAG test data input - serial input for instruction/data loading |
| A1 | PROGRAM_B | Active-low asynchronous reset - forces reconfiguration on falling edge |
| B2 | INIT_B | Open-drain status output - indicates configuration completion or error |
Key Features
| Feature | Design Value |
|---|---|
| Configurable Logic Blocks (CLBs) | 176 CLBs with dual 4-LUTs and flip-flops - enables synchronous state machine implementation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA logic fabric applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC2S50-6TQ144C | 6 ns logic delay (vs. 5 ns); same pinout and logic resources | Slightly lower max frequency (110 MHz vs. 125 MHz) | Acceptable where timing margin allows relaxed speed grade |

FAQ
What is the configuration method supported by XC2S50-5TQG144C?
XC2S50-5TQG144C supports Slave Serial and SelectMAP configuration modes. It requires external configuration memory (e.g., XCFxx PROM) or a host processor to load bitstream at power-up. JTAG is used for programming and boundary-scan, but not for standard configuration. The XC2S50-5TQG144C does not contain on-chip non-volatile configuration memory.
Does XC2S50-5TQG144C support hot-swap or live insertion?
No, XC2S50-5TQG144C does not support hot-swap. Its I/Os are not designed for powered insertion; applying voltage before VCCINT and VCCO stabilization may cause latch-up or damage. Power sequencing per Xilinx DS001 specification - VCCINT before VCCO, both ramped monotonically - is mandatory. The XC2S50-5TQG144C requires controlled power-up to ensure reliable configuration.
What is the maximum operating junction temperature for XC2S50-5TQG144C?
The XC2S50-5TQG144C is rated for commercial temperature range: 0°C to +85°C ambient. Its maximum junction temperature is 100°C under specified thermal conditions (θJA = 36.5°C/W, 20 mm × 20 mm 2-layer board). Thermal design must maintain junction temperature below this limit during sustained operation. The XC2S50-5TQG144C datasheet specifies derating curves above 70°C ambient.
Can XC2S50-5TQG144C interface directly with 5 V TTL logic?
No, XC2S50-5TQG144C I/O banks are 3.3 V tolerant only and not 5 V-tolerant. Direct connection to 5 V TTL outputs risks damaging I/O pins. Level translation (e.g., TXB0108 or discrete resistive dividers) is required for safe interfacing. The XC2S50-5TQG144C supports LVTTL and LVCMOS33 standards, not TTL.
Is XC2S50-5TQG144C RoHS compliant?
Yes, XC2S50-5TQG144C is RoHS compliant per Xilinx documentation (Package Code TQG = lead-free, halogen-free TQFP). It meets EU Directive 2011/65/EU and associated amendments. The XC2S50-5TQG144C part marking includes "G" suffix indicating green packaging, and material declarations are available via AMD's Product Change Notification system.
