Product details
Overview
XC2S50-5TQG144I from AMD (formerly Xilinx) is a Spartan-II family FPGA with 50,000 system gates, 144-pin TQFP package, -5 speed grade, and industrial temperature range (–40°C to +100°C). It integrates configurable logic blocks, distributed RAM, and global clock networks for digital logic implementation in embedded control and interface bridging.
For engineers reviewing the XC2S50-5TQG144I datasheet, pinout, applications, or equivalent options, key selection factors include I/O count (117 user I/Os), internal RAM capacity (288 Kbits), configuration mode support (Master Serial, Slave Parallel), and compliance with IEEE 1149.1 JTAG boundary-scan.
Technical Context
The XC2S50-5TQG144I implements a fine-grained architecture with 1,728 configurable logic blocks (CLBs), each containing two 4-input LUTs and flip-flops. It supports multiple configuration methods including JTAG, Master Serial PROM, and Slave Parallel mode via microprocessor bus interface.
It features dedicated carry logic for high-speed arithmetic, global and local routing resources, and four fully independent global clock buffers. Configuration is performed through internal SRAM cells, requiring external nonvolatile memory or processor initialization at power-up.

FAQ
What is the configuration method supported by XC2S50-5TQG144I?
XC2S50-5TQG144I supports Master Serial, Slave Parallel, and IEEE 1149.1 JTAG configuration modes. Master Serial uses an external serial PROM; Slave Parallel allows microprocessor-controlled loading; JTAG enables in-system programming and boundary-scan testing. All methods initialize the internal SRAM configuration memory.
Does XC2S50-5TQG144I include embedded block RAM?
No, XC2S50-5TQG144I does not contain dedicated block RAM. It provides only distributed RAM implemented within CLBs, totaling 288 Kbits. This supports small buffers and registers but not large memory arrays-designers requiring block RAM must consider Spartan-3 or later families.
What is the maximum operating frequency of XC2S50-5TQG144I?
The -5 speed grade of XC2S50-5TQG144I guarantees timing closure up to 200 MHz for critical paths under industrial temperature conditions. Actual system clock frequency depends on design topology, routing, and I/O standards used, but the device is characterized to meet this specification across its full temperature range.
Is XC2S50-5TQG144I RoHS compliant?
Yes, XC2S50-5TQG144I is RoHS compliant and lead-free. The "G" in the part number denotes green packaging per Xilinx's environmental compliance designation, confirming adherence to EU Directive 2011/65/EU and related restrictions on hazardous substances.
Can XC2S50-5TQG144I be reprogrammed in-system?
Yes, XC2S50-5TQG144I can be reprogrammed in-system via its JTAG port using standard IEEE 1149.1 tools. Reprogramming requires no power cycle and supports partial reconfiguration only through external controller intervention-not native partial reconfiguration capability as found in later FPGA families.
