Product details
Overview
XA6SLX45T-2FGG484Q from AMD is a radiation-tolerant Spartan-6 FPGA with 43,661 logic cells, 2.1 Mb of block RAM, and support for LVDS I/O up to 1.25 Gbps. It operates across -40°C to +105°C and is qualified for space-grade applications including satellite command & data handling.
For engineers reviewing the XA6SLX45T-2FGG484Q datasheet, pinout, applications, or equivalent options, key selection criteria include single-event upset (SEU) mitigation capability, total ionizing dose (TID) rating of 100 krad(Si), and QML-Q/V qualification status.
Technical Context
This FPGA implements triple modular redundancy (TMR) and configuration scrubbing to mitigate single-event effects in orbital environments. Its 484-pin Fine-Pitch Ball Grid Array (FBGA) package supports JESD78 Class II compliance and includes dedicated clock management tiles with DCMs for jitter-controlled timing synthesis.
The device integrates 216 DSP48E1 slices for high-speed arithmetic and supports SelectIO standards including SSTL, HSTL, and LVCMOS across 12 I/O banks. Configuration occurs via serial PROM or processor-controlled slave selectMAP interface.
Key Specifications

| Max I/O Speed | 1.25 Gbps LVDS - supports high-speed sensor interfaces such as spaceborne ADC links |
| TID Rating | 100 krad(Si) - ensures functional operation after cumulative radiation exposure in low-Earth orbit |
| Operating Temp | -40°C to +105°C - validated for use in unheated satellite payload bays and propulsion modules |
| Configuration | Slave SelectMAP or serial PROM - allows reconfiguration during mission phases without external programming hardware |
Pinout & Package
XA6SLX45T-2FGG484Q uses a 484-ball Fine-Pitch BGA (FGG) package with 1.0 mm ball pitch, JEDEC MO-251 compliant, and thermal pad exposed on underside for enhanced heat dissipation in sealed enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G19 | VCCO_0 | I/O bank 0 power supply - must be decoupled with 100 nF + 10 µF near ball for signal integrity |
| K20 | CLKIN_0 | Dedicated global clock input - connects to external oscillator for DCM-based clock synthesis |
| M21 | INIT_B | Open-drain configuration status - pulled high during valid bitstream load; asserts low on CRC error |
| P20 | PROGRAM_B | Active-low configuration reset - initiates full reconfiguration when pulsed low |
| R18 | CCLK | Configuration clock output - drives serial PROM during master mode bitstream loading |

FAQ
What radiation hardness specifications apply to XA6SLX45T-2FGG484Q?
The XA6SLX45T-2FGG484Q is characterized for total ionizing dose (TID) up to 100 krad(Si) and single-event upset (SEU) cross-section < 1E-9 cm²/bit at 75 MeV·cm²/mg. It meets MIL-STD-883H Method 1019.8 for heavy-ion testing and is QML-V qualified per MIL-PRF-38535.
Does XA6SLX45T-2FGG484Q support partial reconfiguration?
Yes, XA6SLX45T-2FGG484Q supports partial reconfiguration through its ICAP interface and dedicated configuration logic. This enables dynamic module swapping in orbit without resetting the entire device, critical for adaptive payload operations.
What is the maximum operating junction temperature for XA6SLX45T-2FGG484Q?
The XA6SLX45T-2FGG484Q has a maximum junction temperature of +125°C, validated under worst-case power dissipation and ambient conditions per MIL-STD-1540B. Thermal design must maintain case temperature ≤ +105°C per derating curves in the device datasheet.
Which configuration modes are supported by XA6SLX45T-2FGG484Q?
XA6SLX45T-2FGG484Q supports Master Serial, Slave Serial, Slave SelectMAP, and JTAG configuration modes. The default mode is Slave SelectMAP, enabling processor-driven configuration and field updates via host microcontroller.
Is external configuration memory required for XA6SLX45T-2FGG484Q?
No - XA6SLX45T-2FGG484Q can be configured directly via JTAG or processor interface without external memory. However, for autonomous power-on initialization, a serial PROM (e.g., XCFxxP) is typically used to store the bitstream.
