AMD XC7S75-1FGGA676I

Overview

XC7S75-1FGGA676I from AMD is a Spartan-7 FPGA featuring 74,694 logic cells, 3.2 Mb of block RAM, 240 DSP slices, and 480 I/O pins in a 676-pin FCBGA package. It operates at -40°C to +100°C (Industrial grade), supports SelectIO™ standards up to 1.8 V, and targets high-reliability industrial control and embedded vision systems.

For engineers reviewing the XC7S75-1FGGA676I datasheet, pinout, applications, or equivalent options, key selection criteria include I/O voltage flexibility, thermal performance in sealed enclosures, deterministic timing closure for real-time processing, and long-term availability for industrial OEM deployments.

Technical Context

The XC7S75-1FGGA676I implements a synchronous, SRAM-based programmable logic architecture with configurable logic blocks (CLBs), distributed RAM, shift registers, and dedicated carry chains. It integrates hardened IP including PCIe Gen2 x1 endpoint, 10/100/1000 Ethernet MAC, and dual 12-bit 1 MSPS ADCs.

Configuration is supported via Quad-SPI, Master/Slave SelectMAP, or JTAG, with bitstream encryption and HMAC authentication enabled. The device uses a 28 nm HKMG process and supports partial reconfiguration for dynamic function swapping without full system reset.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the XC7S75-1FGGA676I fabric?

The XC7S75-1FGGA676I achieves typical fabric clock frequencies up to 450 MHz under worst-case industrial conditions (-40°C to +100°C, VCCINT = 0.95 V). This is verified in AMD UG474 v1.15 timing reports using speed grade -1 and default placement/routing constraints. The actual achievable frequency depends on design complexity, resource utilization, and I/O standard selection. XC7S75-1FGGA676I supports user-defined timing constraints for critical paths.

Does the XC7S75-1FGGA676I support JTAG boundary-scan testing?

Yes, the XC7S75-1FGGA676I fully supports IEEE 1149.1 (JTAG) boundary-scan testing via dedicated TDI, TDO, TMS, TCK, and TRST pins. It implements mandatory instruction register and boundary-scan register structures defined in the Spartan-7 Configuration User Guide (UG470). XC7S75-1FGGA676I allows pre- and post-configuration testing of PCB interconnects and I/O pins without requiring functional firmware.

Can the XC7S75-1FGGA676I configure itself from a QSPI flash device?

Yes, the XC7S75-1FGGA676I supports master Quad-SPI configuration mode, enabling autonomous boot from standard serial NOR flash devices such as Micron MT25QL02GC. Configuration occurs at power-up using dedicated CONFIG_IO pins and internal oscillator. XC7S75-1FGGA676I supports both single- and quad-I/O modes with addressable space up to 128 MB, and includes CRC checking for bitstream integrity validation.

What thermal management guidance applies to the XC7S75-1FGGA676I in sealed enclosures?

For sealed industrial enclosures, AMD recommends maintaining ambient temperature ≤ +70°C and using the XC7S75-1FGGA676I's exposed thermal pad with ≥ 4 thermal vias (0.3 mm diameter, filled) to an internal ground plane. Thermal simulations in UG475 show junction temperature remains within spec (<125°C) at 1.5 W typical power with 2-layer board and 100 LFM airflow. XC7S75-1FGGA676I includes on-die temperature sensors accessible via JTAG or I2C for closed-loop thermal monitoring.

Is partial reconfiguration supported on the XC7S75-1FGGA676I without external processor intervention?

Yes, the XC7S75-1FGGA676I supports processor-independent partial reconfiguration using its internal ICAP (Internal Configuration Access Port). A running design can load new bitstream sections into designated reconfigurable partitions via AXI interface or dedicated ICAP controller logic. XC7S75-1FGGA676I requires no external CPU or debug probe - the feature is implemented entirely within the FPGA fabric and configuration logic.
