Product details
Overview
XCS40XL-4PQ240C from AMD (formerly Xilinx) is a Spartan-XL family FPGA with 40,000 system gates, 240-pin PQFP package, -4 speed grade, and commercial temperature range (0°C to 70°C). It integrates configurable logic blocks, I/O blocks, and interconnect resources for digital logic implementation in embedded control and interface bridging applications.
For engineers reviewing the XCS40XL-4PQ240C datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count, speed grade, package footprint, and configuration memory requirements.
Technical Context
The XCS40XL-4PQ240C implements a fine-grained architecture with 1,280 configurable logic blocks (CLBs), each containing two 3-input LUTs and flip-flops. It supports SRAM-based configuration via external PROM or microprocessor interface.
It features 182 user I/O pins, LVCMOS/LVTTL-compatible signaling, and internal global clock networks with low-skew distribution. Configuration is performed through JTAG or master serial mode using external configuration PROMs such as XCF01S or XCF02S.

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA-based logic implementation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCS30XL-4PQ240C | 30K system gates, same PQFP-240 package and -4 speed grade | Lower gate count limits complex state machine depth and datapath width | Select when design fits within 30K gates and cost sensitivity outweighs headroom needs |
| XCS50XL-4PQ240C | 50K system gates, identical package and speed grade | Higher gate density supports larger control logic or additional peripheral interfaces | Choose when future feature expansion or higher I/O-to-logic ratio is required |
Compared with XCS30XL-4PQ240C and XCS50XL-4PQ240C, the XCS40XL-4PQ240C offers balanced gate density for mid-scale control logic-avoiding underutilization of the 50K variant while providing margin over the 30K part's resource ceiling.

FAQ
What is the configuration method supported by the XCS40XL-4PQ240C?
The XCS40XL-4PQ240C supports master serial configuration using external PROMs (e.g., XCF01S) and JTAG boundary-scan programming. It does not support slave parallel or selectMAP modes. Configuration bitstream is loaded on power-up or after PROGRAM_B assertion, and the device operates in readback-capable mode for verification.
Does the XCS40XL-4PQ240C support hot-swap I/O operation?
No, the XCS40XL-4PQ240C does not support hot-swap I/O. Its I/O structures lack bus-hold, weak pull-up/down, or powered-off protection circuitry. Power must be stable and within specification before asserting signals on any I/O pin to prevent latch-up or damage.
What is the maximum operating frequency of the XCS40XL-4PQ240C?
The XCS40XL-4PQ240C has a -4 speed grade specifying a maximum system clock frequency of 25 MHz under worst-case commercial conditions (0°C to +70°C, VCC = 3.3 V ±5%). Internal register-to-register paths may achieve higher rates depending on routing and logic depth, but 25 MHz is the guaranteed timing closure limit.
Can the XCS40XL-4PQ240C be reprogrammed in-system?
Yes, the XCS40XL-4PQ240C can be reprogrammed in-system via its JTAG TAP controller or through master serial mode using an external microcontroller. Reprogramming requires full configuration reload; partial reconfiguration is not supported in the Spartan-XL architecture.
Is there built-in configuration memory in the XCS40XL-4PQ240C?
No, the XCS40XL-4PQ240C does not include on-chip nonvolatile configuration memory. It relies on external serial PROMs (e.g., XCF01S, XCF02S) or microprocessor-controlled loading for configuration bitstream storage and initialization.
