Product details
Overview
XCS40-4PQ240C from AMD (formerly Xilinx) is a Spartan-XL family FPGA with 40,000 system gates, 240-pin PQFP package, 5.0 V supply, and configurable logic blocks supporting synchronous design. It is used in industrial control I/O modules requiring reconfigurable digital logic and deterministic timing.
For engineers reviewing the XCS40-4PQ240C datasheet, pinout, applications, or equivalent options, key selection factors include voltage tolerance, I/O count, configuration mode support, and legacy 5V system compatibility.
Technical Context
The XCS40-4PQ240C implements a sea-of-gates architecture with configurable logic blocks (CLBs), input/output blocks (IOBs), and interconnect resources. It supports JTAG boundary-scan (IEEE 1149.1) and serial/parallel PROM-based configuration.
Logic density is specified at 40,000 usable gates with up to 288 user I/O pins and 128 CLBs. Timing performance includes 10 ns maximum carry delay and 4.5 ns CLB propagation delay under typical conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Capacity | 40,000 system gates - defines maximum combinational logic complexity supported |
| Supply Voltage | 5.0 V ±10% - requires standard 5V LDO or regulator, not compatible with 3.3V-only systems |
| I/O Pins | 240-pin PQFP with 288 user I/Os - enables high-density board-level interfacing |
| Configuration Mode | Master Serial, Slave Parallel, JTAG - supports in-system programming and factory loading |
| Max CLB Prop Delay | 4.5 ns - determines minimum clock period for synchronous logic paths |
| Operating Temp | 0°C to 70°C - rated for commercial temperature range only |
Pinout & Package
Package: 240-pin Plastic Quad Flat Pack (PQFP), 32 mm × 32 mm, 0.5 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Power Ground | Multiple dedicated pins for low-noise analog/digital reference return |
| VCC | Core & I/O Supply | 5.0 V power for logic and I/O banks; decoupling required per bank |
| PROGRAM | Configuration Init | Active-low signal that clears configuration memory and resets internal state |
| DIN | Serial Data Input | Primary data path for Master Serial configuration mode |
| TCK/TMS/TDI/TDO | JTAG Interface | Supports IEEE 1149.1 boundary-scan testing and ISP |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA-based logic replacement applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCS40-5PQ240C | Higher speed grade (5 ns CLB delay vs. 4.5 ns), same package and pinout | Required where tighter setup/hold margins exist in high-frequency control loops | Select when target clock frequency exceeds 85 MHz and timing closure fails on XCS40-4PQ240C |
| XCS30-4PQ240C | Lower density (30,000 gates), identical voltage, package, and I/O structure | Suitable for cost-sensitive designs with reduced logic resource requirements | Choose when design fits within 75% of XCS40-4PQ240C's CLB count and budget constraints dominate |
Compared with XCS40-4PQ240C, the XCS40-5PQ240C offers marginally improved timing performance without layout change, while the XCS30-4PQ240C reduces gate count and cost but constrains logic scalability for future firmware updates.

FAQ
What is the configuration voltage requirement for XCS40-4PQ240C?
The XCS40-4PQ240C requires a 5.0 V ±10% supply for both core logic and I/O operation. It does not support 3.3 V or mixed-voltage I/O banks. Configuration PROMs must also be 5V-compatible, and the PROGRAM pin is active-low with 5V-tolerant input threshold.
Does XCS40-4PQ240C support in-system programming (ISP)?
Yes, XCS40-4PQ240C supports in-system programming via its JTAG port (TCK/TMS/TDI/TDO pins), compliant with IEEE 1149.1. This allows configuration and boundary-scan testing without removing the device from the PCB. Serial and parallel modes require external PROM or controller access.
What is the maximum operating junction temperature for XCS40-4PQ240C?
The XCS40-4PQ240C is rated for commercial temperature range only: 0°C to +70°C ambient. Its maximum junction temperature is 110°C under worst-case power dissipation. Thermal design must ensure case temperature remains below 70°C with adequate PCB copper pour and airflow.
Can XCS40-4PQ240C replace XCS40-3PQ240C in an existing design?
Yes, XCS40-4PQ240C is pin-compatible and functionally upward-compatible with XCS40-3PQ240C. The -4 speed grade offers improved timing margins (4.5 ns CLB delay vs. 5.0 ns), allowing higher clock frequencies or relaxed PCB trace routing. No layout change is needed.
Is there a recommended configuration PROM for XCS40-4PQ240C?
Xilinx XCF01S, XCF02S, or XCF04S serial PROMs are recommended for Master Serial configuration of XCS40-4PQ240C. These devices operate at 5V, match the FPGA's configuration timing, and support automatic power-on loading without external controller intervention.
