AMD XC7S100-1FGGA484Q

Overview

XC7S100-1FGGA484Q from AMD is a Spartan-7 FPGA with 100K logic cells, 484-pin Fine-Pitch Flip-Chip Ball Grid Array (FCBGA) package, -1 speed grade, and industrial temperature range (–40°C to +100°C). It integrates dual ARM Cortex-A9 MPCore processors, 2.5 Gbps transceivers, and hardened PCIe Gen2 x2 endpoint support for embedded vision and industrial control applications.

For engineers reviewing the XC7S100-1FGGA484Q datasheet, pinout, applications, or equivalent options, key selection criteria include logic capacity, transceiver data rate, PCIe integration level, thermal performance in sealed enclosures, and I/O bank voltage flexibility for mixed-signal interfacing.

Technical Context

The XC7S100-1FGGA484Q implements a full-featured programmable logic fabric with 100,000 ASIC-equivalent logic cells, 460 user I/Os distributed across 12 I/O banks, and integrated Block RAM (2.5 MB total). It supports SelectIO standards including LVCMOS, SSTL, HSTL, and differential signaling (LVDS, TMDS) up to 1.25 Gbps per lane.

This device includes a hardened PCIe Gen2 x2 endpoint block with AXI4-Lite configuration interface, dual 2.5 Gbps GTY transceivers, and integrated analog-to-digital converter (XADC) with dual 12-bit 1 MSPS channels for on-chip monitoring of temperature and supply voltages.

FAQ

What is the maximum supported I/O standard voltage for XC7S100-1FGGA484Q?

XC7S100-1FGGA484Q supports I/O standards up to 1.8 V across its 12 independently powered I/O banks. Each bank's VCCO can be set to 1.2 V, 1.35 V, 1.5 V, or 1.8 V, enabling direct interfacing with DDR3, LPDDR3, and legacy 3.3 V peripherals via appropriate bank configuration and termination.

Does XC7S100-1FGGA484Q include an integrated analog-to-digital converter?

Yes, XC7S100-1FGGA484Q includes the XADC - a dual 12-bit, 1 MSPS analog-to-digital converter with dedicated VP/VN inputs. It measures on-die temperature and supply voltages (VCCINT, VCCAUX) and supports external analog monitoring with ±0.5% accuracy over the full industrial temperature range.

Is XC7S100-1FGGA484Q qualified for automotive applications?

No, XC7S100-1FGGA484Q is qualified for industrial temperature range (–40°C to +100°C) and is not AEC-Q100 certified. For automotive use, AMD offers the XA7S100 variant, which undergoes additional qualification testing and includes automotive-grade screening and documentation.

What clock sources are required for the GTY transceivers in XC7S100-1FGGA484Q?

The GTY transceivers in XC7S100-1FGGA484Q require a dedicated differential reference clock input (e.g., 100 MHz LVDS or LVPECL) applied to GTYP0_Q0_CLK_* pins. An external crystal oscillator or clock generator meeting jitter specifications (<1.5 ps RMS) must be used; on-chip PLLs alone cannot meet transceiver timing requirements.

Can XC7S100-1FGGA484Q operate without external configuration memory?

No, XC7S100-1FGGA484Q requires external non-volatile configuration memory (e.g., SPI Flash) to load its bitstream at power-up. It does not include embedded configuration ROM. The device supports Master SPI, Slave Serial, and JTAG configuration modes, with fallback support enabled via M[2:0] pin settings.
