Product details
Overview
XCS20-3PQ208C from AMD (formerly Xilinx) is a Spartan-2 family FPGA with 20,000 system gates, 176 user I/Os, and configured in a 208-pin PQFP package; it supports 3.3V I/O operation and operates at -3 speed grade for industrial temperature range (-40°C to +85°C), used in legacy industrial control logic replacement.
For engineers reviewing the XCS20-3PQ208C datasheet, pinout, applications, or equivalent options, key selection considerations include I/O count, speed grade timing compliance, PQFP thermal and routing constraints, and Spartan-2 family configuration memory retention behavior.
Technical Context
The XCS20-3PQ208C implements configurable logic blocks (CLBs) with four-input LUTs and flip-flops, distributed RAM, and dedicated carry logic for arithmetic functions. It uses SRAM-based configuration memory loaded via JTAG or serial PROM at power-up.
It supports SelectI/O standards including LVTTL, LVCMOS, and PCI-compliant signaling on dedicated I/O banks. Configuration is volatile and requires external non-volatile storage for persistent operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Gates | 20,000 system gates - defines maximum combinational logic capacity for gate-equivalent design mapping |
| User I/Os | 176 - number of bidirectional programmable pins available for interface signal routing |
| Speed Grade | -3 - specifies worst-case propagation delay (Tpd) and setup/hold timing margins per data sheet |
| Operating Temp | -40°C to +85°C - industrial temperature range requiring thermal-aware PCB layout and derating |
| I/O Voltage | 3.3V - mandates compatible voltage-level peripherals and termination schemes |
| Package | PQFP-208 - 208-lead plastic quad flat pack with 0.5 mm pitch, requiring fine-pitch soldering process |
Pinout & Package
Package: PQFP-208, 28 × 28 mm body, 0.5 mm lead pitch, gull-wing leads, JEDEC MS-026 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Multiple dedicated pins provide low-impedance return paths for core and I/O power domains |
| VCCINT | Core supply | 2.5V internal logic supply; requires local decoupling and noise-sensitive regulation |
| VCCO | I/O supply | 3.3V bank-specific supply; each I/O bank has independent VCCO for mixed-voltage interfacing |
| TCK/TMS/TDI/TDO | JTAG boundary-scan | IEEE 1149.1-compliant test and configuration interface; no external programming hardware required |
| PROGRAM_B | Configuration reset | Active-low asynchronous input that clears configuration memory and initiates reconfiguration sequence |
Key Features
| Feature | Design Value |
|---|---|
| Configurable CLBs | Each CLB contains two 4-input LUTs and two flip-flops, enabling efficient implementation of synchronous logic and state machines |
| Distributed RAM | Up to 128 bits per CLB usable as fast synchronous RAM or shift registers without block RAM resources |
| SelectI/O Technology | Supports LVTTL/LVCMOS 3.3V, with programmable slew rate and drive strength per pin for EMI and signal integrity control |
| Global Clock Networks | Four dedicated low-skew global clock lines with buffer fanout to all CLBs and I/Os for timing-critical synchronization |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA logic replacement applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCS20-4PQ208C | Faster -4 speed grade; identical pinout and logic resources | Required where Tco < 4.5 ns or Tsu > 3.2 ns is mandated by system timing budget | Select XCS20-4PQ208C only if timing closure fails with -3 grade; same PCB layout and configuration files apply |
| XCS30-3PQ208C | 30,000-gate capacity; same package, speed grade, and I/O count | Needed when additional logic density is required for feature expansion without board change | Use XCS30-3PQ208C when CLB utilization exceeds 85% in XCS20-3PQ208C implementations |
Compared with XCS20-3PQ208C, the -4 variant improves worst-case timing margin without altering footprint or configuration flow, while the XCS30-3PQ208C provides headroom for logic growth within identical thermal and routing constraints.

FAQ
What is the configuration method supported by XCS20-3PQ208C?
XCS20-3PQ208C uses SRAM-based configuration loaded at power-up via JTAG (IEEE 1149.1) or serial PROM. Since configuration memory is volatile, an external non-volatile device must store the bitstream. The XCS20-3PQ208C does not support master serial or slave parallel modes natively without external controller logic.
Does XCS20-3PQ208C support mixed-voltage I/O operation?
Yes, XCS20-3PQ208C supports mixed-voltage I/O through bank-wise VCCO assignment: each I/O bank can be powered independently at 3.3V, enabling simultaneous LVTTL and LVCMOS signaling. Core voltage remains fixed at 2.5V (VCCINT), and no level-shifting transceivers are needed for same-supply interfaces.
What is the maximum operating frequency for global clock networks in XCS20-3PQ208C?
The XCS20-3PQ208C global clock networks support up to 125 MHz under worst-case industrial conditions (-3 speed grade, 85°C). This value derives from Tco and Tsu specifications in the Spartan-2 data sheet and assumes proper PCB routing and termination. Higher frequencies may be achievable in benign environments but are not guaranteed.
Is XCS20-3PQ208C RoHS compliant?
XCS20-3PQ208C is available in both RoHS-compliant (Pb-free) and non-RoHS versions. The RoHS-compliant variant carries the suffix "C" in the ordering code and uses matte tin lead finish. Compliance documentation, including test reports and material declarations, is provided upon request for XCS20-3PQ208C shipments.
Can XCS20-3PQ208C be reprogrammed in-system?
Yes, XCS20-3PQ208C supports in-system programming via its JTAG port without requiring power cycle or physical rework. The XCS20-3PQ208C accepts new configuration bitstreams dynamically, enabling field updates and diagnostic mode activation. However, configuration is lost on power removal unless backed by external non-volatile storage.
