AMD XC3S500E-5FGG320C

Overview

XC3S500E-5FGG320C from AMD (formerly Xilinx) is a Spartan-3E FPGA featuring 500,000 system gates, 11,200 logic cells, and 224 I/O pins in a 320-pin Fine-Pitch Ball Grid Array (FBGA) package. It operates at -5 speed grade (5 ns CLB delay), supports SelectIO™ standards up to 333 Mbps, and targets cost-sensitive embedded control and interface bridging applications.

For engineers reviewing the XC3S500E-5FGG320C datasheet, pinout, applications, or equivalent options, key selection criteria include logic density, I/O count, voltage compatibility (3.3V/2.5V/1.8V/1.2V), distributed RAM capacity (288 kbits), and configuration mode support (Master Serial, Slave Serial, JTAG).

Technical Context

The XC3S500E-5FGG320C implements a hierarchical architecture with configurable logic blocks (CLBs), block RAM (18 kbits total), digital clock managers (DCMs) for jitter reduction and frequency synthesis, and dedicated multipliers for arithmetic acceleration. It supports dual-data-rate (DDR) I/O and includes dedicated carry logic for high-speed arithmetic.

Configuration is performed via external PROM or processor-controlled slave parallel mode, with boundary-scan testing compliant to IEEE 1149.1. The device uses 1.2V core voltage and supports multiple I/O bank voltages, enabling mixed-voltage interfacing without level shifters.

FAQ

What is the core voltage requirement for XC3S500E-5FGG320C?

The XC3S500E-5FGG320C requires a nominal 1.2 V ±3% core supply (VCCINT) delivered through dedicated power pins. This voltage powers the FPGA fabric and CLBs; deviation beyond tolerance risks timing violations or configuration loss. Decoupling capacitors must be placed per Xilinx UG331 guidelines, and the supply must support peak current demands during configuration and high-activity operation.

Does XC3S500E-5FGG320C support JTAG configuration?

Yes, XC3S500E-5FGG320C supports IEEE 1149.1 JTAG configuration via TCK, TMS, TDI, and TDO pins. This mode enables in-system programming, boundary-scan testing, and debugging without requiring external PROM. Configuration occurs after power-up when M2:M0 pins are set to 010, and the device remains in JTAG mode until reset or reconfiguration.

How many Digital Clock Managers (DCMs) does XC3S500E-5FGG320C include?

XC3S500E-5FGG320C integrates four Digital Clock Managers (DCMs). Each DCM provides clock deskew, frequency synthesis (up to 32× multiplication), phase shifting (in 0.75 ns steps), and duty cycle correction. These are essential for synchronizing multiple clock domains in applications like video timing generation or multi-channel data acquisition using XC3S500E-5FGG320C.

What I/O standards are supported by XC3S500E-5FGG320C?

XC3S500E-5FGG320C supports LVCMOS, LVTTL, PCI, HSTL Class I/II, SSTL2 Class I/II, and differential standards including LVDS and RSDS. I/O banks operate independently at 1.2V, 1.5V, 1.8V, 2.5V, or 3.3V, allowing mixed-voltage interfacing. All standards are implemented in hardware with programmable slew rate and drive strength per pin group.

Is XC3S500E-5FGG320C RoHS compliant?

Yes, XC3S500E-5FGG320C is RoHS compliant and lead-free, meeting Directive 2011/65/EU requirements. The FBGA package uses matte tin finish on solder balls, and the device is rated for Pb-free reflow profiles (JEDEC J-STD-020D). Full compliance documentation, including substance declarations, is available in AMD's Product Change Notification archives for XC3S500E-5FGG320C.
