Product details
Overview
XC7A15T-1CSG325I from AMD (Xilinx) is a Spartan-7 FPGA with 15,840 logic cells, 1.2 Mb of block RAM, and 120 DSP slices, packaged in a 325-pin CSGA (Chip Scale Grid Array) with 0.8 mm pitch. It operates at -1 speed grade (1.0 V core, industrial temperature range -40°C to +100°C) and targets cost-sensitive embedded control and interface bridging applications.
For engineers reviewing the XC7A15T-1CSG325I datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (210 user I/Os), transceiver support (no GTY/GTP), configuration interface (SPIx4/JTAG), and thermal profile for convection-cooled industrial PCBs.
Technical Context
The XC7A15T-1CSG325I implements a 28 nm HKMG process-based architecture with CLB-based logic fabric, dedicated carry chains, and distributed RAM. It supports SelectIO standards including LVCMOS, SSTL, HSTL, and differential signaling up to 1.25 Gbps without transceivers.
Configuration is performed via master SPI or JTAG; no internal configuration memory is included. The device lacks high-speed serial transceivers (GTP/GTY), distinguishing it from higher-tier Artix-7 parts, and relies on fabric-based I/O timing closure for parallel interfaces.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC7A35T-1CSG325I | Higher logic density (33,280 LUTs), same package and speed grade | Supports larger state machines or additional peripheral controllers without board change | Choose when design requires >15K LUTs but must retain CSG325 footprint and thermal profile |

FAQ
What is the maximum supported I/O standard voltage for XC7A15T-1CSG325I?
The XC7A15T-1CSG325I supports I/O standards from 1.2 V to 3.3 V across its eight selectable I/O banks. Each bank's VCCO must be set to match the connected interface voltage, and mixed-voltage operation is permitted. The device does not support 1.0 V or 1.5 V-only standards like HSTL Class I or SSTL-15 without level-shifting.
Does XC7A15T-1CSG325I include built-in high-speed transceivers?
No, the XC7A15T-1CSG325I does not include GTY, GTP, or any high-speed serial transceivers. It relies on SelectIO primitives and IDELAY/ODELAY for parallel or source-synchronous interfaces up to 1.25 Gbps. For PCIe, SATA, or multi-gigabit Ethernet, a higher-tier Artix-7 or Kintex-7 device is required.
What configuration modes are supported by XC7A15T-1CSG325I?
The XC7A15T-1CSG325I supports Master SPI x4, Slave Serial, JTAG, and Boundary Scan configuration modes. Master SPI x4 is most common for production, enabling fast loading from quad-SPI flash. JTAG is used for debugging and programming during development. No internal configuration memory is present - external nonvolatile storage is mandatory.
Is XC7A15T-1CSG325I qualified for automotive applications?
The XC7A15T-1CSG325I carries an industrial temperature rating (–40°C to +100°C) and meets JESD22-A108 reliability testing, but it is not AEC-Q100 qualified. For automotive use, it may be deployed in cabin or body-control modules where full qualification is not mandated, but not in powertrain or ADAS safety-critical domains without additional system-level validation.
Can XC7A15T-1CSG325I directly interface with DDR3 memory?
Yes, the XC7A15T-1CSG325I includes a hard Memory Interface Generator (MIG) supporting DDR3 SDRAM up to 800 Mbps data rate (400 MHz clock) with 16-bit or 32-bit data buses. It requires external termination and careful PCB layout for signal integrity, and supports only single-ended address/control lines - not differential clocks or DQS gating.
