Product details
Overview
XCS40XL-5PQ240C from AMD (formerly Xilinx) is a Spartan-XL family FPGA with 40,000 system gates, 5 ns maximum input-to-output delay, and 196 user I/O pins in a 240-pin PQFP package. It integrates configurable logic blocks, distributed RAM, and global clock networks for embedded control and interface bridging in industrial motion controllers.
For engineers reviewing the XCS40XL-5PQ240C datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count, speed grade (-5), PQFP thermal profile, and legacy 3.3 V/5 V mixed-voltage I/O support.
Technical Context
The XCS40XL-5PQ240C implements a fine-grain architecture with 1,280 configurable logic blocks (CLBs), each containing two 3-input LUTs and flip-flops. It supports up to four global clocks and includes dedicated carry logic for arithmetic functions.
Configuration is performed via serial mode using an external PROM or parallel slave mode with a microcontroller. The device operates at 3.3 V core voltage with 5 V-tolerant I/Os, enabling direct interfacing with legacy TTL and CMOS peripherals without level shifters.
Key Specifications

FAQ
What is the maximum operating temperature range for the XCS40XL-5PQ240C?
The XCS40XL-5PQ240C is rated for commercial temperature operation from 0 °C to +70 °C. This range is validated per the device's DC and AC specifications in the official Xilinx Spartan-XL data sheet. Operation outside this range may result in timing violations or configuration loss. The XCS40XL-5PQ240C does not support industrial or extended temperature grades.
Does the XCS40XL-5PQ240C support JTAG boundary-scan testing?
No, the XCS40XL-5PQ240C does not implement IEEE 1149.1 (JTAG) boundary-scan. Configuration and debugging rely on dedicated pins (PROGRAM, INIT, DONE) and serial/parallel modes. Test access requires external logic analyzers or custom test firmware. The XCS40XL-5PQ240C predates JTAG integration in Spartan families.
Can the XCS40XL-5PQ240C be reconfigured in-system after power-up?
Yes, the XCS40XL-5PQ240C supports in-system reconfiguration via its parallel slave mode, allowing a host microcontroller to reload the configuration bitstream dynamically. This capability is used for field-upgradable logic in test equipment. The XCS40XL-5PQ240C retains no configuration memory internally and requires external PROM or processor control for each power cycle.
What are the power supply requirements for the XCS40XL-5PQ240C?
The XCS40XL-5PQ240C requires a regulated 3.3 V ±5% supply for the core logic and a separate 3.3 V or 5 V supply for I/O banks, depending on interface voltage. Total typical power consumption is 350 mW at 25 MHz activity. The XCS40XL-5PQ240C has no internal voltage regulators and relies on external low-noise LDOs.
Is the XCS40XL-5PQ240C pin-compatible with newer Spartan families?
No, the XCS40XL-5PQ240C is not pin-compatible with Spartan-II, Spartan-3, or later families. Its PQ240 package and I/O architecture differ significantly in voltage handling, configuration protocol, and pin function allocation. Migration to newer devices requires PCB redesign. The XCS40XL-5PQ240C remains a legacy part with fixed pinout and interface definitions.
