It operates across -40°C to +100°C and is qualified for space applications including satellite command/data handling and payload interface control.
For engineers reviewing the XA6SLX45-2FGG484I datasheet, pinout, applications, or equivalent options, key selection factors include total logic capacity, radiation tolerance level (up to 100 krad(Si)), I/O voltage flexibility (1.2 V to 3.3 V), and extended temperature operation without derating.
Technical Context
The XA6SLX45-2FGG484I implements a configurable logic fabric based on 6-input LUTs and distributed RAM, with integrated DSP48E slices supporting 18×25-bit multiply-accumulate operations. It includes dual 12-bit ADCs with 1 MSPS sampling rate and dedicated clock management tiles with DCMs and PLLs.
Configuration is performed via serial NOR flash or JTAG, with SEU mitigation using built-in EDAC on configuration memory and optional user-implemented TMR logic. The device supports SelectIO standards including LVCMOS, LVDS, and SSTL, with programmable slew rate and drive strength per bank.
