AMD XC7A15T-1FGG484C

Overview

XC7A15T-1FGG484C from AMD (formerly Xilinx) is a Spartan-7 FPGA featuring 15,840 logic cells, 1.2 Mb of block RAM, and 120 DSP slices, packaged in a 484-pin Fine-Pitch Flip-Chip BGA (FFG484). It supports I/O standards up to 1.8 V and operates at -40°C to +100°C junction temperature, targeting cost-sensitive industrial control and embedded vision interfaces.

For engineers reviewing the XC7A15T-1FGG484C datasheet, pinout, applications, or equivalent options, key selection criteria include logic density, I/O voltage flexibility, thermal rating, and availability of transceiver-capable banks for high-speed serial links.

Technical Context

The XC7A15T-1FGG484C implements a 28 nm HKMG process-based architecture with configurable logic blocks (CLBs), distributed RAM, shift registers, and dedicated carry chains. It integrates SelectIO™ technology supporting LVCMOS, LVDS, SSTL, and HSTL I/O standards across 12 I/O banks.

It includes dual-register flip-flops per LUT, clock management tiles with MMCM and PLL support, and configuration via JTAG, SPI, or master/slave serial modes. No integrated transceivers - serial interface capability relies on I/O bank–based LVDS or differential signaling.

Key Specifications

Pinout & Package

FAQ

What is the maximum supported I/O standard voltage for XC7A15T-1FGG484C?

XC7A15T-1FGG484C supports I/O standards up to 1.8 V across its 12 I/O banks. Each bank can be independently configured for voltages from 1.2 V to 1.8 V, enabling direct interfacing with mixed-voltage peripherals such as 1.8 V sensors and 3.3 V legacy controllers - provided appropriate VCCO and reference voltage settings are applied per bank.

Does XC7A15T-1FGG484C include built-in high-speed transceivers?

No, XC7A15T-1FGG484C does not integrate multi-gigabit transceivers. High-speed serial communication must be implemented using SelectIO™-based differential standards (e.g., LVDS, TMDS) within I/O banks. For PCIe, Gigabit Ethernet, or USB 3.x physical layer support, external PHY devices or higher-tier Artix-7/FPGA families are required.

What configuration modes are supported by XC7A15T-1FGG484C?

XC7A15T-1FGG484C supports Master SPI, Slave Serial, and JTAG configuration modes. Master SPI enables standalone boot from external flash; Slave Serial allows bitstream loading from a host processor; JTAG is used for programming, debugging, and boundary-scan testing. Configuration mode is selected via M0–M2 pins during power-up.

Can XC7A15T-1FGG484C operate reliably at 100°C junction temperature?

Yes, XC7A15T-1FGG484C is rated for industrial temperature range (-40°C to +100°C) and qualified to operate continuously at 100°C junction temperature. Thermal design must ensure adequate PCB copper area, airflow, or heatsinking to maintain junction temperature within spec under worst-case power dissipation conditions.

How many block RAM primitives are available in XC7A15T-1FGG484C?

XC7A15T-1FGG484C contains 1.2 Mb of total block RAM, implemented as 80 x 18 Kb BRAM primitives. These can be configured as true dual-port RAM, ROM, or shift register memory, and are distributed across the FPGA fabric to minimize routing congestion and maximize utilization in data-path intensive designs.
