AMD XC3S1500-5FGG320C

Overview

XC3S1500-5FGG320C from AMD (formerly Xilinx) is a Spartan-3 FPGA with 1,471,248 system gates, 116 I/O pins, and 1500 logic cells, fabricated on 90 nm CMOS technology and operating at 500 MHz system clock frequency. It integrates distributed RAM, shift registers, and digital clock managers for embedded control and interface bridging in industrial motion controllers.

For engineers reviewing the XC3S1500-5FGG320C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O voltage support (3.3V/2.5V), TQFP-compatible 320-pin Fine-Pitch BGA package, -5 speed grade timing, and industrial temperature range (0°C to 85°C).

Technical Context

The XC3S1500-5FGG320C implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), block RAM (1,728 kbits), and dedicated multipliers (40 × 18-bit). It supports SelectIO standards including LVCMOS, LVTTL, PCI, and SSTL.

Digital Clock Managers (DCMs) provide phase-matched clock synthesis, duty-cycle correction, and frequency synthesis with ±1% jitter tolerance over temperature and voltage. Configuration is performed via Master Serial mode using external PROM or JTAG boundary-scan interface.

FAQ

What is the maximum operating temperature range for XC3S1500-5FGG320C?

The XC3S1500-5FGG320C is rated for industrial temperature operation from 0°C to +85°C ambient. This range is validated per Xilinx DS099 specification and applies to all speed grades in the FG320 package. Thermal derating is not required within this envelope, and junction temperature remains within safe limits under typical I/O loading and 1.2 V core supply conditions.

Does XC3S1500-5FGG320C support JTAG boundary-scan testing?

Yes, XC3S1500-5FGG320C fully supports IEEE 1149.1 JTAG boundary-scan with dedicated TCK, TMS, TDI, TDO, and TRST pins. The JTAG interface enables in-system programming, configuration verification, and real-time debugging without requiring external configuration PROM. All boundary-scan operations comply with Xilinx configuration mode specifications.

Can XC3S1500-5FGG320C be configured using Master Serial mode?

Yes, XC3S1500-5FGG320C supports Master Serial configuration using an external serial PROM connected to CCLK, DIN, and DONE signals. In this mode, the FPGA drives CCLK and reads configuration bitstream sequentially. The process is defined in Xilinx UG071 and requires no external controller, making it ideal for standalone deployment.

What I/O standards are supported by XC3S1500-5FGG320C?

XC3S1500-5FGG320C supports LVCMOS, LVTTL, PCI, SSTL18, SSTL2, HSTL, and differential standards including LVDS and RSDS. Each I/O bank is independently configurable for voltage levels from 1.2 V to 3.3 V. These capabilities are documented in Xilinx DS099 Table 22 and verified across all speed grades in the FG320 package.

Is XC3S1500-5FGG320C pin-compatible with other Spartan-3 devices in the FG320 package?

XC3S1500-5FGG320C shares the same 320-pin FBGA footprint and ball assignment with XC3S500E-5FGG320C, XC3S1000-5FGG320C, and XC3S2000-5FGG320C. Power and configuration pins are identically placed; I/O pin functions are consistent across the family, enabling hardware reuse when migrating between densities within the same speed grade.
