AMD XCS30XL-4PQ208I

Overview

XCS30XL-4PQ208I from AMD (formerly Xilinx) is a Spartan-XL family FPGA featuring 30,000 system gates, 208-pin PQFP package, -4 speed grade, and industrial temperature range (-40°C to +100°C). It integrates configurable logic blocks, distributed RAM, and I/O banks supporting 3.3V and 5V-tolerant signaling for embedded control and interface bridging.

For engineers reviewing the XCS30XL-4PQ208I datasheet, pinout, applications, or equivalent options, key selection criteria include logic density, I/O voltage flexibility, industrial-grade thermal performance, and legacy reprogrammable logic suitability for long-lifecycle industrial upgrades.

Technical Context

The XCS30XL-4PQ208I implements a fine-grained architecture with 1,472 configurable logic blocks (CLBs), each containing two 3-input LUTs and flip-flops. It supports in-system programmability via JTAG boundary-scan and includes dedicated carry logic for high-speed arithmetic.

Configuration is performed through external serial PROM or parallel mode using a master processor. The device lacks internal configuration memory and requires external bitstream loading at power-up, limiting use in zero-delay boot scenarios.

FAQ

What is the configuration method for XCS30XL-4PQ208I?

The XCS30XL-4PQ208I requires external configuration via serial or parallel mode using an external PROM or microcontroller. It contains no on-chip nonvolatile memory, so the bitstream must be loaded at every power-on. This architecture supports field updates but necessitates external storage and initialization logic in the system design for XCS30XL-4PQ208I.

Does XCS30XL-4PQ208I support 5V logic interfaces?

Yes, XCS30XL-4PQ208I features 5V-tolerant input buffers across all I/O banks, enabling direct connection to 5V TTL and CMOS peripherals without level-shifting circuitry. Its VCCO pins are independently configurable per bank for 3.3V operation while maintaining 5V input tolerance-critical for legacy system integration in XCS30XL-4PQ208I deployments.

What is the maximum operating frequency of XCS30XL-4PQ208I?

The XCS30XL-4PQ208I is rated at -4 speed grade, guaranteeing a maximum internal CLB-to-CLB clock frequency of 125 MHz under industrial temperature conditions. Actual system-level timing depends on routing delay and logic depth; timing analysis must be performed using Xilinx Foundation or ISE tools specific to XCS30XL-4PQ208I.

Is XCS30XL-4PQ208I pin-compatible with other Spartan-XL devices?

XCS30XL-4PQ208I shares the PQ208 package footprint with XCS30-4PQ208I and XCS40XL-4PQ208I, but I/O function allocation and bank voltage assignments differ. While PCB land patterns are identical, direct substitution requires verification of I/O banking, VCCO assignment, and configuration pin behavior-XCS30XL-4PQ208I is not a drop-in replacement without design review.

What temperature range is XCS30XL-4PQ208I qualified for?

XCS30XL-4PQ208I is specified for industrial temperature operation from -40°C to +100°C ambient. This rating is validated per Xilinx qualification standards and applies to the full functional specification-including I/O voltage tolerance, timing parameters, and configuration reliability-making XCS30XL-4PQ208I suitable for uncooled industrial enclosures and motor drive cabinets.
