AMD XCS30XL-4PQ208C

Overview

XCS30XL-4PQ208C from AMD (formerly Xilinx) is a Spartan-XL family FPGA with 30,000 system gates, 208-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 industrial control and communication interface designs.

For engineers reviewing the XCS30XL-4PQ208C datasheet, pinout, applications, or equivalent options, key selection factors include logic capacity, I/O count, speed grade, operating temperature, and QFP packaging compatibility with legacy PCB layouts.

Technical Context

The XCS30XL-4PQ208C implements a fine-grained architecture with configurable logic cells (CLBs), dedicated carry logic for arithmetic, and programmable interconnect matrices. It supports SRAM-based configuration via JTAG or serial PROM and includes boundary-scan test capability per IEEE 1149.1.

It features 160 user I/O pins, internal global clock routing, and supports mixed-voltage I/O operation (3.3V or 5V tolerant depending on bank configuration). Configuration data retention requires external nonvolatile memory.

Manufacturer

AMD acquired Xilinx in 2022 and now develops adaptive computing platforms including FPGAs, ACAPs, and related software tools.

The Spartan-XL family was originally designed by Xilinx for cost-sensitive, high-volume applications requiring moderate logic density and reliable PQFP packaging - especially in industrial and communications infrastructure.

FAQ

What is the maximum operating frequency of the XCS30XL-4PQ208C?

The XCS30XL-4PQ208C has a -4 speed grade, guaranteeing a maximum internal clock frequency of 125 MHz under commercial temperature and voltage conditions. This rating applies to critical path delays within the CLB fabric and excludes I/O register-to-pad timing, which depends on external loading and board layout.

Does the XCS30XL-4PQ208C support in-system programming?

Yes, the XCS30XL-4PQ208C supports in-system programming via its IEEE 1149.1 JTAG interface (TCK/TMS/TDI/TDO pins). Configuration can be loaded from an external serial PROM or through JTAG boundary-scan controllers, enabling field updates and manufacturing test without removing the device.

What power supplies are required for the XCS30XL-4PQ208C?

The XCS30XL-4PQ208C requires two primary supplies: VCC = 3.3 V ±5% for core logic, and VCCO = 3.3 V or 5 V (per I/O bank) for output drivers. Each supply must be independently decoupled with low-ESR capacitors placed within 1 cm of respective pins to ensure stable operation.

Is the XCS30XL-4PQ208C pin-compatible with other Spartan-XL devices?

The XCS30XL-4PQ208C shares the PQFP-208 package and pinout with other Spartan-XL devices in the same package option, including XCS30XL-3PQ208C and XCS40XL-4PQ208C. However, speed grade and logic capacity differences affect timing closure and resource utilization - full functional equivalence requires design verification.

What is the role of the PROGRAM_B pin on the XCS30XL-4PQ208C?

The PROGRAM_B pin on the XCS30XL-4PQ208C is an active-low input that forces the device into configuration mode when asserted. It clears internal configuration memory and initiates reload from the external PROM or JTAG chain, enabling reliable recovery after power-up or error conditions in the XCS30XL-4PQ208C.
