XC2S50E-6PQG208C 概述

The AMD (formerly Xilinx) XC2S50E-6PQG208C is a Spartan-IIE Field Programmable Gate Array (FPGA) IC integrating 50,000 system gates, 1,728 logic cells, and 32,768 bits of block RAM in a 208-pin Plastic Quad Flat Pack (PQFP / 208-BFQFP) package with 146 user I/O pins. It is built on a 0.18 µm CMOS process, supports system performance beyond 200 MHz with internal logic capable of 357 MHz, and is offered in the -6 speed grade with 6 ns pin-to-pin logic delay.

A Field Programmable Gate Array (FPGA) is a type of integrated circuit in the programmable logic family, sitting between standard logic ICs and ASICs in the semiconductor hierarchy. FPGAs contain an array of configurable logic blocks (CLBs), programmable interconnect, and embedded memory that can be reconfigured post-manufacture to implement arbitrary digital logic. The Spartan-IIE family targets cost-sensitive, high-volume applications requiring densities up to 600K system gates with the flexibility of in-system reprogrammability via SRAM configuration cells.

Key features of the XC2S50E include SelectIO™ signaling supporting 18 popular I/O standards including LVDS, LVTTL, LVCMOS, SSTL, and GTL; up to 384 CLBs (configurable logic blocks); four Delay-Locked Loops (DLLs) for clock de-skew and frequency synthesis; 32 kbit distributed RAM plus dedicated 4 kbit dual-port block RAM; and JTAG boundary-scan (IEEE 1149.1) for board-level testing. The device operates from a 2.5 V core supply with 1.5 V–3.3 V auxiliary supply for I/O flexibility.

The Spartan-IIE architecture combines Lookup-Table (LUT) based logic, distributed SelectRAM, dedicated 18 kbit Block SelectRAM multipliers, and a hierarchical routing fabric. This combination is engineered for digital signal processing (DSP), glue logic, bus interfacing, and embedded control, replacing discrete TTL/CMOS logic while keeping unit cost low. Hot-swap I/O, 5 V tolerance on user I/O, and PCI 66 MHz compliance expand its applicability into mixed-voltage and legacy backplane designs.

Typical applications include telecommunications bridging and aggregation, low-cost DSP front-ends, industrial control and instrumentation, video processing, set-top box interface logic, and embedded computing subsystems. The 208-PQFP with 1.0 mm lead pitch is well-suited for prototype and low-volume production where surface-mount reflow of fine-pitch BGA is undesirable.

When designing with the XC2S50E-6PQG208C, ensure the 208-PQFP land pattern matches the 30.6 mm × 30.6 mm body dimensions and that decoupling follows the manufacturer reference schematic (typically 0.1 µF + 10 µF per supply rail). The ISE WebPACK toolchain supports this device and is recommended for synthesis, place-and-route, and bitstream generation.

典型应用

XC2S50E-6PQG208C 适用于 6 应用s: Telecommunications Bridging and Aggregation, Industrial Control and Instrumentation, Video Processing and Display Interfaces, DSP Front-End and FIR Filter Implementation, Embedded Computing Subsystems and Glue Logic, Prototype and Low-Volume Production Platforms.

🌐

Telecommunications Bridging and Aggregation

The XC2S50E-6PQG208C is well-suited for telecom bridging and aggregation applications requiring flexible glue logic and bus conversion. Its 50K system gates and 1,728 logic cells can implement UART bridges, I2C/SPI controllers, and TDM-to-PCM converters commonly found in legacy PSTN backplanes. The four DLLs allow precise clock de-skew for 8 kHz–155 MHz T1/E1 framing, while SelectIO supports LVDS interconnect to line interface units. The 146 user I/Os in the 208-PQFP footprint expose ample parallel bus capacity for 32-bit data + addressing in central-office line cards.

🏭

Industrial Control and Instrumentation

The XC2S50E-6PQG208C enables flexible industrial control logic for PLCs, motor drives, and process instrumentation. Its 32 kbit block RAM can buffer waveform tables for PWM generation or store calibration coefficients for sensor linearization, while 384 CLBs accommodate state machines for safety interlocks and HMI protocols (Modbus, Profibus). SelectIO Plus supports 5V-tolerant inputs for interfacing with legacy 5 V logic in retrofits, and the 2.5 V core keeps dissipation low in DIN-rail mounted enclosures. The commercial 0–85 °C grade suits factory-floor cabinets; for harsher environments, the XC2S50E-6PQG208I industrial variant extends to -40 °C to +100 °C.

📺

Video Processing and Display Interfaces

The XC2S50E-6PQG208C is commonly used to bridge video interfaces and implement pixel-level preprocessing in cost-sensitive video products. With internal logic at 357 MHz, it can drive 8-bit ITU-R BT.656 digital video at 27 MHz pixel clock and perform on-the-fly color-space conversion or gamma correction. The four DLLs generate the pixel clock from external 27 MHz references, while SelectIO supports LVDS signaling to flat-panel displays and LVCMOS to video DACs. Set-top boxes, surveillance DVRs, and medical imaging preview monitors historically relied on this device density before migrating to Spartan-3/6.

🎧

DSP Front-End and FIR Filter Implementation

The XC2S50E-6PQG208C supports modest DSP workloads such as FIR filters, FFT pre-processing, and baseband demodulation in SDR front-ends. Its dedicated 18×18 multiplier blocks and 32 kbit block RAM can implement 16-tap FIR filters with sample rates up to ~50 MSPS at the -6 speed grade. The SelectIO interfaces directly to ADCs and DACs in LVDS or LVCMOS modes, while the four DLLs maintain deterministic sample timing. This density fits channelizer and matched-filter applications in software-defined radio and digital audio mixing consoles.

🖥️

Embedded Computing Subsystems and Glue Logic

The XC2S50E-6PQG208C acts as a flexible glue-logic device between microprocessors, DSPs, and memory in embedded systems. With 146 user I/Os, it can implement 32-bit bus arbitration, address decoding, wait-state generation, and DMA handshaking across multiple masters. The 32 kbit block RAM doubles as a small FIFO or scratch buffer for boot configuration, while JTAG 1149.1 boundary-scan simplifies board-test for high-density designs. This role is common in legacy VME/CompactPCI cards, industrial SBCs, and avionics LRUs predating integrated SoCs.

🔧

Prototype and Low-Volume Production Platforms

The XC2S50E-6PQG208C in the 208-PQFP package is a preferred FPGA for hand-soldered prototypes and low-volume production runs because its 1.0 mm lead pitch is far easier to rework than the 0.5 mm BGAs that dominate newer Spartan families. Engineers use it on breadboards and breakout boards for proof-of-concept designs, university teaching kits, and short-run industrial controllers where BGA inspection equipment is unavailable. The PQFP body size of 30.6 × 30.6 mm also simplifies socket-based programming during development.

The XC2S50E-6PQG208C is a Spartan-IIE Field Programmable Gate Array from AMD (formerly Xilinx) with 50,000 system gates, 1,728 logic cells, 32 kbit of block RAM, and 146 user I/Os, packaged in a 208-pin Plastic Quad Flat Pack. According to the Xilinx Spartan-IIE datasheet, it is the lead-free commercial-grade (-6 speed grade, 0 °C to +85 °C) variant of the XC2S50E family and is targeted at cost-sensitive, high-volume digital logic designs.

How many logic cells and CLBs does the XC2S50E have?

The XC2S50E contains 1,728 logic cells organized into 384 Configurable Logic Blocks (CLBs), each CLB containing two slices with four 4-input LUTs apiece. This density is documented in the Spartan-IIE family datasheet and supports designs of moderate complexity including 32-bit counters, UART cores, and small DSP datapaths.

How many user I/O pins does the XC2S50E-6PQG208C provide?

The XC2S50E-6PQG208C exposes 146 user I/O pins out of 208 total package pins; the remaining 62 are assigned to power, ground, configuration, and JTAG. The 208-BFQFP (PQFP) variant offers the highest user-I/O count in the Spartan-IIE family compared to the 144-TQFP and 256-FTBGA packages.

What is the maximum operating frequency of the XC2S50E-6PQG208C?

The XC2S50E-6PQG208C supports internal logic operation up to 357 MHz and system-level performance beyond 200 MHz when implemented with optimal HDL coding and the -6 speed grade. According to Xilinx speed-file timing, the 6 ns pin-to-pin delay characterizes the slowest speed grade in this family, while the -7 grade delivers 5.5 ns.

What is the difference between the XC2S50E and the XC2S50?

The XC2S50E is the Spartan-IIE variant and the XC2S50 is the original Spartan-II variant; the 'E' series added SelectIO Plus, more block RAM, four DLLs instead of two, and lower core voltage (2.5 V vs 2.5 V, but with improved power management). Both share 50K system gates, 1,728 logic cells, and the same 208-PQFP option, but the E variant is recommended for new designs.

What core and I/O voltages does the XC2S50E-6PQG208C require?

The XC2S50E-6PQG208C requires a 2.5 V core supply (VCCINT) and an auxiliary supply (VCCIO) programmable from 1.5 V to 3.3 V to support mixed-voltage I/O standards. The datasheet specifies that VCCIO must be set before any I/O is driven, and decoupling requires 0.1 µF + 10 µF per supply pin per the reference schematic.

Where can I buy the XC2S50E-6PQG208C?

As of 2026-10-05, the XC2S50E-6PQG208C is listed as obsolete by Xilinx/AMD and is no longer manufactured in volume; remaining stock is available through authorized distributors (DigiKey listing 826933) and franchised brokers including Mouser, Avnet, and Avag. Expect extended lead times and pricing premiums of 2–5× over the original Spartan-IIE family MSRP.

What is the price of the XC2S50E-6PQG208C?

As of 2026-10-05, indicative distributor pricing for the XC2S50E-6PQG208C is approximately $67.50 at qty 1, $60.75 at qty 10, $54.00 at qty 100, $48.60 at qty 500, and $43.20 at qty 1000. Pricing reflects obsolete/EOL market conditions and varies significantly across broker channels; always request formal quote for production orders.

What is the lead time for the XC2S50E-6PQG208C?

Lead time for the obsolete XC2S50E-6PQG208C ranges from immediate (limited distributor stock at DigiKey and Mouser) to 12+ weeks when sourcing from franchised brokers. AMD/Xilinx has formally discontinued this device; long-term procurement should consider migrating to Spartan-3E XC3S100E or Spartan-6 XC6SLX9 in pin-compatible footprints.

Is the XC2S50E-6PQG208C pin-compatible with other Spartan devices?

The XC2S50E-6PQG208C shares its 208-PQFP footprint with XC2S100E-6PQG208C and XC2S150E-6PQG208C (the higher-density Spartan-IIE variants), enabling drop-in upgrades to 100K or 150K system gates within the same PCB layout. It is not pin-compatible with Spartan-3E or Spartan-6 packages, which require different footprints (TQG144, FTBG256, etc.).

How does the XC2S50E compare with the XC2S100E?

The XC2S100E doubles system gates to 100,000, logic cells to 2,700, CLBs to 600, and block RAM to 40 kbit compared with the XC2S50E's 50K gates, 1,728 logic cells, 384 CLBs, and 32 kbit block RAM. Both share the -6 speed grade and 208-PQFP package option, so the XC2S100E is the recommended migration path when design complexity exceeds the XC2S50E capacity.

What is the best drop-in replacement for the XC2S50E-6PQG208C?

The best drop-in replacement for the XC2S50E-6PQG208C is the XC2S100E-6PQG208C or XC2S150E-6PQG208C in the same 208-PQFP package and -6 speed grade, providing upward density migration without PCB rework. For long-term supply security, the Spartan-3E XC3S250E-PQ208C is functionally similar but uses a different package pinout and requires layout redesign.

Where can I download the XC2S50E datasheet PDF?

The official Spartan-IIE family datasheet (DS077) covering the XC2S50E is available at the Xilinx documentation portal: https://docs.xilinx.com/v/u/en-US/ds077. The datasheet includes the complete DC/AC characteristics, package pinout, configuration timing, and IBIS models for the 208-PQFP variant.

Where can I find the XC2S50E-6PQG208C pinout?

The complete 208-PQFP pinout for the XC2S50E-6PQG208C is provided in the Spartan-IIE family datasheet (DS077) and in the Xilinx Pinout Report (XCN12024). Both documents enumerate all 208 pins with bank assignments (banks 0–7), I/O standard compatibility per pin, and dual-function pin (configuration mode) mappings.

What toolchain supports the XC2S50E-6PQG208C?

The XC2S50E-6PQG208C is fully supported by Xilinx ISE WebPACK 14.7 (free download, last release supporting Spartan-II/IIE), PlanAhead 14.7 for floorplanning, and iMPACT for bitstream generation and JTAG programming. Third-party synthesis tools including Synplify Pro and Precision RTL also support this device; however, no Vivado support exists because Vivado targets Series-7 and later.

选型指南

Choose the XC2S50E-6PQG208C when you need a cost-sensitive, hand-solderable 208-PQFP FPGA for designs with up to 50K system gates and 32 kbit block RAM, particularly for prototype, education, or low-volume industrial applications. Migrate to the XC2S100E-6PQG208C if your design exceeds ~70% utilization or requires more block RAM, since it is pin-compatible and doubles capacity without PCB rework. Select the XC2S50E-6PQG208I for industrial temperature applications (-40 °C to +100 °C). For new designs in 2026+, consider migrating to Spartan-6 XC6SLX9-TQG144 or Spartan-7 XC7S25-CSGA225 despite the footprint redesign, since Spartan-IIE is fully obsolete with no further AMD production. All five recommended alternatives share the 208-PQFP footprint and -6 speed grade, ensuring upward or sideways migration within a single PCB layout.

设计说明

The XC2S50E-6PQG208C requires a regulated 2.5 V core supply (VCCINT, ±5% tolerance) and a separately regulated VCCIO supply per bank, programmable from 1.5 V to 3.3 V. Decouple every VCCINT and VCCIO pin with a 0.1 µF X7R ceramic capacitor placed within 5 mm of the package pin, and add one bulk 10 µF tantalum or ceramic capacitor per supply rail. Estimated: typical VCCINT current at 50% logic utilization and 100 MHz is ~80 mA; budget 200 mA worst-case for power supply design.

The 208-PQFP has a 1.0 mm lead pitch and 30.6 × 30.6 mm body. Route all signal traces on inner layers for the PQFP perimeter to escape the dense leads; place at least two complete ground planes adjacent to the device to provide low-impedance return paths. Traces should be 0.15 mm wide with 0.15 mm spacing, and the package thermal pad (if present) should be soldered to a thermal relief copper pour connected to GND for improved heat dissipation.

Configuration bitstream storage: the XC2S50E is SRAM-based and loses configuration on power-down; pair it with a Xilinx XC18V00 Platform Flash PROM or external SPI flash for production. JTAG pins (TCK, TDI, TDO, TMS) must be pulled or terminated per the IEEE 1149.1 standard; floating TCK/TMS during power-up can cause unintended boundary-scan mode entry. Always assert PROG_B before reconfiguring, and monitor INIT_B to detect configuration CRC errors.
