Product details
Overview
XCS20XL-4PQ208I from AMD (formerly Xilinx) is a Spartan-XL family FPGA with 20,000 system gates, 192 I/O pins, and a 4 ns CLB propagation delay. It features 1,280 logic cells, supports 3.3 V operation, and is rated for industrial temperature range (–40°C to +85°C). It is used in low-cost, high-volume embedded control and interface bridging applications.
For engineers reviewing the XCS20XL-4PQ208I datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count, speed grade (-4), PQ208 package compatibility, industrial temperature rating, and legacy 3.3 V core voltage support.
Technical Context
The XCS20XL-4PQ208I implements configurable logic blocks (CLBs) with four-input LUTs and flip-flops, distributed RAM, and dedicated carry logic. It supports IEEE 1149.1 JTAG boundary-scan testing and in-system programmability via serial PROM or microprocessor interface.
Configuration is performed through a master serial mode using an external PROM or parallel slave mode via an 8-bit data bus. The device lacks internal configuration memory and requires external configuration source at power-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Capacity | 20,000 system gates - defines maximum combinational logic complexity supported |
| Speed Grade | -4 - guarantees 4 ns CLB propagation delay under industrial conditions |
| I/O Pins | 192 user-programmable I/Os - supports high-pin-count interface bridging |
| Supply Voltage | 3.3 V ± 0.3 V - requires single 3.3 V rail; not compatible with 2.5 V or 1.8 V systems |
| Operating Temp | –40°C to +85°C - qualified for industrial environments without derating |
| Package | PQ208 - 208-pin plastic quad flat pack, 28 × 28 mm, 0.5 mm pitch |
Pinout & Package
PQ208 is a 208-pin plastic quad flat pack with 52 pins per side, 0.5 mm pitch, and 28 mm × 28 mm body size. Thermal pad is absent; no exposed die attach pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Multiple dedicated pins required for noise suppression and signal integrity |
| VCC | Core supply | 3.3 V power for logic array; decoupling capacitors mandatory per datasheet |
| IOCLK | Input clock | Dedicated global clock input with low-skew routing to all CLBs |
| PROGRAM | Configuration reset | Active-low signal that clears configuration memory and initiates reconfiguration |
| DIN | Serial config data | Serial input for master serial configuration mode using external PROM |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| XCS10XL-4PQ208I | 10,000-gate capacity, same PQ208 package and -4 speed grade | Lower logic density limits complex state machines and larger bus interfaces | Select when design fits within 10K gates and cost reduction is prioritized over headroom |

FAQ
What is the configuration method supported by the XCS20XL-4PQ208I?
The XCS20XL-4PQ208I supports master serial configuration using an external PROM and parallel slave configuration via an 8-bit data bus. It does not contain on-chip configuration memory and must be reloaded at each power-on. Configuration data is loaded into SRAM-based logic cells, making it volatile until reprogrammed.
Does the XCS20XL-4PQ208I support JTAG boundary-scan testing?
Yes, the XCS20XL-4PQ208I fully complies with IEEE 1149.1 JTAG boundary-scan standards. This enables board-level interconnect testing, in-circuit debugging, and programming without requiring physical access to individual pins during production test.
What is the maximum operating frequency for the XCS20XL-4PQ208I?
The XCS20XL-4PQ208I has a guaranteed 4 ns CLB propagation delay (speed grade -4), enabling typical system clock frequencies up to 125 MHz for register-to-register paths. Actual maximum frequency depends on design placement, routing, and logic depth.
Can the XCS20XL-4PQ208I operate at 2.5 V?
No, the XCS20XL-4PQ208I is specified only for 3.3 V ± 0.3 V core supply operation. It lacks internal voltage regulation or multi-voltage I/O support, and operation outside this range may cause functional failure or permanent damage.
Is the XCS20XL-4PQ208I still in active production?
The XCS20XL-4PQ208I is a legacy Spartan-XL device discontinued by AMD/Xilinx. Aetrix Electronics maintains verified, traceable inventory sourced from authorized channels and supports long-term supply for existing designs through lifecycle management programs.
