AMD XA7A35T-2CSG325I

Overview

XA7A35T-2CSG325I from AMD is a Kintex-7 FPGA with 35,000 logic cells, 2.5 Gbps transceivers, and -2 speed grade in a 324-pin CSG package. It integrates block RAM, DSP slices, and clock management tiles for high-performance embedded vision and industrial control applications.

For engineers reviewing the XA7A35T-2CSG325I datasheet, pinout, applications, or equivalent options, key selection criteria include I/O voltage support (1.2–3.3 V), transceiver lane count (8), and thermal performance (industrial temperature range –40°C to +100°C).

Technical Context

The XA7A35T-2CSG325I implements a 28 nm HKMG process architecture with configurable logic blocks (CLBs), 18 × 25 multiplier DSP slices, and integrated SelectIO technology supporting LVDS, SSTL, and HSTL standards. It includes dual 12-bit 1 MSPS ADCs and hardened PCI Express® Gen2 endpoints.

Its clocking system features six MMCMs and six PLLs for jitter reduction and multi-domain clock synthesis. The device supports partial reconfiguration and AXI4-Stream interfaces for real-time data path flexibility in deterministic systems.

Key Specifications

Pinout & Package

FAQ

What is the maximum supported I/O standard voltage for XA7A35T-2CSG325I?

The XA7A35T-2CSG325I supports I/O voltages from 1.2 V to 3.3 V across its SelectIO banks. Each bank is independently configurable for standards including LVDS, SSTL-18, SSTL-25, and HSTL. This allows direct interfacing with DDR3 memory, image sensors, and industrial communication peripherals without level-shifting circuitry.

Does XA7A35T-2CSG325I include built-in analog-to-digital conversion capability?

Yes, the XA7A35T-2CSG325I integrates two 12-bit, 1 MSPS auxiliary ADC channels. These are dedicated to monitoring internal supply voltages and die temperature-not for general-purpose signal acquisition. They provide telemetry data via dedicated AXI-Lite registers accessible to soft processors or configuration logic.

Is XA7A35T-2CSG325I pin-compatible with other Kintex-7 devices in the CSG325 package?

XA7A35T-2CSG325I shares the same 324-ball CSG package footprint and pinout with XC7A35T-2CSG325I and XC7A50T-2CSG325I. However, XA7A35T-2CSG325I includes radiation-hardened configuration memory and enhanced SEU mitigation-features not present in commercial-grade variants.

What transceiver protocols does XA7A35T-2CSG325I natively support?

The XA7A35T-2CSG325I transceivers support protocols including CPRI, JESD204B, and Aurora at up to 2.5 Gbps per lane. They do not include native PCIe Gen2 endpoint logic-this is implemented in the hardened block only in XA7A35T-2CSG325I's companion part XA7A35T-2FGG484I with different package and I/O count.

How is partial reconfiguration implemented on XA7A35T-2CSG325I?

Partial reconfiguration on XA7A35T-2CSG325I uses frame-based bitstream loading through ICAP (Internal Configuration Access Port). It requires dedicated logic partitioning during design, boundary constraints, and runtime controller logic. The feature is fully supported in Vivado 2022.2 and later, enabling dynamic function swaps in avionics and medical systems without full FPGA reset.
