RTAX250SL-1LG624B - 250K Rad-Tolerant FPGA, 649MHz | Microchip
The Microchip Technology RTAX250SL-1LG624B is a radiation-tolerant FPGA from the RTAX-SL family offering 250,000 equivalent system gates, 2816 logic cells (4224 logic cells per distributor data), and a maximum clock frequency of 649 MHz, built on a 0.15 um CMOS process with a 1.5V core voltage and housed in a 624-pin ceramic LGA package supplied in a box. A radiation-tolerant FPGA is a field-programmable gate array designed to survive the radiation environment of space and high-altitude flight, where single-event effects (SEE) and total ionizing dose (TID) would upset standard commercial devices. The RTAX-SL family sits within Microchip's (formerly Actel/Microsemi) space flight portfolio, forming the programmable logic tier of a satellite avionics hierarchy that includes antifuse RTAX-S devices, flash-based ProASIC3L parts, and radiation-hardened RTG4-generation FPGAs. Key features of this device include the SL low-power variant of the RTAX architecture, embedded SRAM blocks with built-in FIFO control logic, segmentable clock conditioning circuitry, chip-wide highway routing for low-skew global signaling, and dedicated carry logic for arithmetic functions. These system-level features originate from Microsemi's commercial AXCELERATOR-style fabric, repackaged for space-grade reliability. Architecturally, the RTAX-SL fabric consists of clustered logic modules (C-cells and R-cells) interconnected through a rich hierarchical routing network, with VersaTiles supporting both combinational and sequential implementations. The -1 speed grade denotes the fastest commercial speed bin available for this die, and the B suffix denotes the radiation-tolerant flow with data derived from the same 0.15 um metallization used across the family. Typical applications include satellite payload data processing, spacecraft telemetry and command (TM/TC) interfaces, orbit-control and attitude-control electronics, and space-based sensor interfacing, where single-chip form factor, live-at-power-up operation, and low power consumption matter more than raw gate density. A key design consideration is prototyping: the ceramic LGA-624 footprint cannot be reflowed on standard FR-4 prototypes easily, so Microchip provides footprint-compatible adaptor boards and an EDIF netlist/pinout conversion methodology for prototyping with RTAX-S/SL devices.

Typical applications include satellite onboard data handling, payload processing, spacecraft avionics and telemetry interfaces, and radiation-tolerant prototyping ahead of a flight-unit RTAX4000S/SL design. The PROTO variant lets designers validate board, firmware, and system integration on flight-identical silicon and packaging at a lower cost. When designing with this device, note that PROTO units are not fully flight-qualified; substitute RTAX4000S/SL flight-grade orderable codes before launch programs. Ensure the 1.5V core rail meets the 1.425V to 1.575V window, and verify signal integrity at the 1.00mm-pitch CGA land pattern.

RTAX4000S-LG1272V - 4M-Gate Rad-Tolerant FPGA | Microchip
The Microchip Technology (Actel/Microsemi) RTAX4000S-LG1272V is a radiation-tolerant FPGA with 4,000,000 equivalent system gates, 40320 CLBs, and 60480 logic cells, housed in a 1272-pin ceramic LG1272 column grid array package. It operates from a nominal 1.5V core supply across a -55C to +125C military temperature range. A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the ionizing radiation and single-event effects (SEE) encountered in space flight. Within the programmable logic hierarchy, the RTAX4000S sits in the family of high-density antifuse FPGAs -> programmable logic devices -> semiconductors. Unlike COTS FPGAs, rad-tolerant devices such as the RTAX-S family combine SEU-hardened flip-flops with a ceramic package and screening flow suited to space-flight system designers. Key features include SEU-hardened registers that eliminate the need for Triple-Module Redundancy (TMR) in many designs, single-event upset immunity up to LETTH MeV.cm2/mg with an SEU rate below 10-10 errors per bit-day, live-at-power-up operation, and a true single-chip form factor that removes the need for external configuration devices. Low-power CMOS processing reduces the power budget critical to satellite and deep-space missions. The antifuse architecture is inherently one-time programmable: the configuration is permanent, immune to configuration-memory upsets, and valid immediately at power-up. The 1272-pin ceramic package with column grid array terminations provides the mechanical robustness and hermeticity demanded by launch environments. Typical applications include satellite payload processing, spacecraft avionics and command/data handling, deep-space probe instrument interfaces, and launch-vehicle electronics. Designers choose the RTAX4000S when 4M-gate capacity, SEU hardness, and flight heritage are required simultaneously. Design consideration: antifuse programming is permanent, so the complete design flow - simulation, timing closure, and a hardware prototype such as the RTAX4000S-1LG1272PROTO - should be completed before device programming.

The 0.15um CMOS process yields low static power consumption, a decisive advantage in power-limited satellites. Architecturally, the RTAX-SL family derives from the commercial Axcelerator family, giving designers a proven fabric with cluster-based logic modules, chip-wide routing, and high-performance I/O. A documented prototyping flow lets designs be validated on commercial Axcelerator devices using footprint-compatible adaptor boards and EDIF netlist conversion before flight-device commit. Typical applications include satellite payload data processing, spacecraft bus control, telemetry and telecommand interfaces, and radiation-exposed instrumentation where live-at-power-up operation removes the need for external configuration memory, a common failure point in space systems. Design consideration: because the device is one-time programmable antifuse, verify the netlist fully on the prototyping flow before programming flight units, and budget board clearances for the 1272-column ceramic package's reflow and inspection requirements.
