For engineers reviewing the XA6SLX45-2CSG484I datasheet, pinout, applications, or equivalent options, key selection criteria include single-event latch-up (SEL) immunity, total ionizing dose (TID) tolerance up to 100 krad(Si), and configuration memory scrubbing capability.
Technical Context
The XA6SLX45-2CSG484I implements a reconfigurable logic fabric based on 6-input LUTs and integrated DSP48E slices capable of 18×25-bit multiply-accumulate operations. It includes dedicated clock management tiles with DCMs supporting phase-shifted and frequency-synthesized outputs.
Configuration is performed via serial or parallel mode using SEU-hardened configuration memory. The device supports JTAG boundary-scan per IEEE 1149.1 and includes internal voltage monitoring for VCCINT, VCCAUX, and VCCO rails.

FAQ
What is the total ionizing dose (TID) rating for XA6SLX45-2CSG484I?
The XA6SLX45-2CSG484I is rated for 100 krad(Si) total ionizing dose, verified per MIL-STD-883 TM1019. This specification applies to the full device under continuous 2.5 V VCCAUX and 1.2 V VCCINT bias during irradiation, and confirms functionality retention in low-Earth orbit missions exceeding five years.
Does XA6SLX45-2CSG484I support partial reconfiguration?
Yes, the XA6SLX45-2CSG484I supports partial reconfiguration through its hardened configuration port and frame-based bitstream architecture. This capability allows dynamic replacement of logic modules without resetting the entire device, enabling adaptive payload functions in operational spacecraft.
What JTAG standards does XA6SLX45-2CSG484I comply with?
XA6SLX45-2CSG484I complies fully with IEEE 1149.1 (JTAG) for boundary-scan testing and debug. It implements TAP controller, instruction register, and boundary-scan register per the standard, and supports INTEST, EXTEST, and SAMPLE/PRELOAD instructions for production test and in-field diagnostics.
Is configuration memory scrubbing implemented in hardware for XA6SLX45-2CSG484I?
Yes, XA6SLX45-2CSG484I includes dedicated hardware scrubbers that autonomously detect and correct single-event upsets in configuration memory. Scrubbing occurs continuously during operation without CPU intervention and uses internal parity checking across all configuration frames.
What is the maximum supported LVDS data rate on XA6SLX45-2CSG484I I/O banks?
The XA6SLX45-2CSG484I supports LVDS signaling at up to 1.25 Gbps per differential pair, validated under worst-case voltage and temperature conditions (-40°C, VCCO = 2.5 V). This rate enables direct interfacing with SpaceWire PHYs and radiation-hardened serializer ICs without external retiming.
