Product details
Overview
XC7A15T-1FGG484I from AMD (Xilinx) is a Spartan-7 FPGA featuring 15,840 logic cells, 690 Kbits of block RAM, and 120 DSP slices, packaged in a 484-pin Fine-Pitch Flip-Chip BGA (FFG484) with -1 speed grade and industrial temperature range (-40°C to +100°C). It targets cost-sensitive embedded control, industrial I/O bridging, and sensor interface applications requiring deterministic timing and low static power.
For engineers reviewing the XC7A15T-1FGG484I datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (200 user I/Os), supported I/O standards (LVCMOS, LVDS, SSTL), configuration interface (SPIx4, JTAG), and thermal performance under sustained operation at 100°C ambient.
Technical Context
The XC7A15T-1FGG484I implements a 28 nm HKMG process-based architecture with configurable logic blocks (CLBs), 36-Kbit block RAMs, and dedicated clock management tiles (CMTs) containing PLLs and MMCMs. It supports transceiver-less serial connectivity via SelectIO technology with programmable slew rate and drive strength per bank.
Configuration is performed via master SPI or JTAG; bitstream security includes AES-256 encryption and HMAC authentication. The device lacks integrated transceivers but supports source-synchronous interfaces up to 1.25 Gbps using IDELAY/ODELAY and ISERDES/OSERDES primitives.

FAQ
What is the maximum operating junction temperature for XC7A15T-1FGG484I?
The XC7A15T-1FGG484I is rated for industrial temperature operation with a maximum junction temperature of +100°C. This specification is validated per JEDEC JESD22-A108 and supports fanless deployment in enclosures where ambient temperatures reach 85°C, provided PCB thermal design maintains θJA ≤ 25°C/W. Thermal derating is not required below this limit.
Does XC7A15T-1FGG484I support JTAG boundary-scan testing?
Yes, XC7A15T-1FGG484I fully supports IEEE 1149.1 (JTAG) boundary-scan testing via dedicated TCK, TMS, TDI, and TDO pins. The device implements mandatory instructions (SAMPLE/PRELOAD, EXTEST, BYPASS) and optional IDCODE, enabling board-level interconnect verification and in-system programming without requiring SPI flash.
Can XC7A15T-1FGG484I configure from a single x4 SPI flash device?
Yes, XC7A15T-1FGG484I supports master SPI x4 configuration mode using pins D0–D3. A single Micron MT25QL02GC or Spansion S25FL512S flash device can store the full bitstream and boot the XC7A15T-1FGG484I in under 120 ms, eliminating need for multi-device parallel configuration schemes.
What I/O standards are supported on XC7A15T-1FGG484I banks?
XC7A15T-1FGG484I supports LVCMOS (1.2 V to 3.3 V), LVDS, BLVDS, RSDS, differential SSTL, and HSTL across its 12 I/O banks. Each bank's VCCO must be set independently; LVDS operation requires adjacent pairs and internal termination, while SSTL-18 supports DDR3 address/command interfaces directly.
Is XC7A15T-1FGG484I pin-compatible with other Spartan-7 FPGAs in FFG484 package?
XC7A15T-1FGG484I shares identical pinout and package dimensions with XC7A35T-1FGG484I and XC7A50T-1FGG484I within the Spartan-7 family. Power, configuration, and I/O pin assignments are fully aligned, enabling hardware reuse across density variants without PCB redesign.
