Product details
Overview
XCS20XL-4VQ100C from AMD (formerly Xilinx) is a Spartan-XL family FPGA with 20,000 system gates, 100-pin VQFP package, -4 speed grade, and commercial temperature range (0°C to 70°C). It implements synchronous digital logic in embedded control, industrial interface, and communication protocol bridging applications.
For engineers reviewing the XCS20XL-4VQ100C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (84 user I/Os), internal RAM (288 bits), configurable logic blocks (CLBs), global clock routing, and IEEE 1149.1 JTAG boundary-scan support.
Technical Context
The XCS20XL-4VQ100C uses a segmented architecture with configurable logic blocks (CLBs), input/output blocks (IOBs), and interconnect resources. It supports synchronous design with up to four global clock networks and includes dedicated carry logic for arithmetic functions.
This device implements SRAM-based configuration memory and requires external PROM or processor-based initialization. It supports in-system programmability via JTAG and operates with 5.0 V ±10% core and I/O supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Capacity | 20,000 system gates - defines maximum combinational logic density for gate-equivalent synthesis |
| User I/O Pins | 84 - provides parallel interface capability for microcontroller co-processing or peripheral bridging |
| Speed Grade | -4 - guarantees 25 MHz maximum clock frequency for CLB-to-CLB paths under worst-case conditions |
| Supply Voltage | 5.0 V ±10% - requires standard TTL-compatible power rail; no separate I/O or core voltage rails |
| Operating Temperature | 0°C to 70°C - qualified for commercial-grade environments only, not extended or industrial range |
| Configuration Mode | Master Serial, Slave Parallel, JTAG - enables flexible programming during development and in-field updates |
Pinout & Package

FAQ
What is the configuration method supported by XCS20XL-4VQ100C?
The XCS20XL-4VQ100C supports Master Serial, Slave Parallel, and IEEE 1149.1 JTAG configuration modes. It requires external configuration PROM or microcontroller-driven serial loading. The device does not include on-chip non-volatile memory and loses configuration on power loss, necessitating reinitialization at startup. XCS20XL-4VQ100C configuration time depends on mode: ~100 ms for Master Serial, ~20 ms for Slave Parallel.
Does XCS20XL-4VQ100C support hot-swap operation?
XCS20XL-4VQ100C includes HSWAPEN pin functionality to manage I/O weak pull-ups during power ramp-up, enabling controlled hot-swap behavior. However, it lacks internal power sequencing or brown-out detection, so external circuitry is required to ensure VCC ramps monotonically and meets 5 V ±10% tolerance before configuration. XCS20XL-4VQ100C must be held in PROGRAM* reset until power stabilizes.
What is the maximum operating frequency of XCS20XL-4VQ100C?
The XCS20XL-4VQ100C has a -4 speed grade specifying 25 MHz maximum system clock frequency for CLB-to-CLB paths under worst-case commercial temperature and voltage conditions. Registered I/O paths achieve up to 20 MHz, and carry-chain arithmetic reaches 33 MHz. XCS20XL-4VQ100C timing reports must be verified using Xilinx Foundation or Alliance software with -4 speed files.
Can XCS20XL-4VQ100C replace XCS20-4VQ100C in existing designs?
No. XCS20XL-4VQ100C is not a drop-in replacement for the original XCS20-4VQ100C. The XL version features enhanced I/O drive strength, improved noise immunity, and added bus-hold circuitry-but requires updated timing constraints and may exhibit different power-up behavior due to HSWAPEN pin handling. XCS20XL-4VQ100C also uses different configuration bitstream formats incompatible with pre-XL tools.
Is XCS20XL-4VQ100C RoHS compliant?
XCS20XL-4VQ100C was manufactured prior to full RoHS enforcement and is exempt under EU Directive 2011/65/EU Annex III for industrial monitoring and control equipment. It contains leaded solder finish and leaded die attach. Aetrix Electronics provides full material declarations and legacy compliance documentation for XCS20XL-4VQ100C upon request.
