RTAX2000DL-1CQ352B 개요
A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the ionizing radiation environments of space-flight systems, including total ionizing dose (TID) and single-event effects. Within the power/semiconductor hierarchy, it sits under FPGA -> programmable logic device -> digital CMOS integrated circuit. The RTAX-DSP family members are one-time-programmable (OTP) antifuse devices, meaning the configuration is nonvolatile, live at power-up, and immune to configuration upsets caused by radiation - a decisive advantage over SRAM-based FPGAs in orbit.
Key features include up to 120 DSP mathblocks with 18-bit x 18-bit multiply-accumulate blocks running at 125 MHz, up to 540 kbits of embedded SRAM with optional EDAC protection, total dose tolerance of 300 krad (Si) functional (200 krad per parametric specification per distributor summaries of the datasheet), and highly reliable nonvolatile antifuse technology. Chip-wide highway routing, segmentable clocks, and embedded FIFO control logic support high-throughput signal processing payloads.
The device is fabricated in advanced CMOS and based on the commercial Axcelerator architecture, inheriting its high-performance fabric while adding radiation hardening by design and qualification. The ceramic CQFP package provides hermetic sealing required for space-flight assembly flows and compatibility with standard high-reliability solder and socket mounting processes.
Typical applications include satellite payload signal processing, spacecraft on-board data handling, telemetry and telecommand controllers, radiation-exposed sensor interfaces, and launch-vehicle avionics where single-chip, live-at-power-up operation and low power consumption are mandatory.
A critical design consideration is the OTP nature of the antifuse fabric: programming is irreversible, so designers should prototype using the Aldec RTAX prototyping adaptors (flash-based ProASIC3E technology) before committing flight units.

일반적인 애플리케이션
RTAX2000DL-1CQ352B 적합 용도: 6 애플리케이션s: Satellite Payload Signal Processing, Spacecraft On-Board Data Handling (OBDH), Telemetry and Telecommand (TM/TC) Controllers, Radiation-Exposed Sensor Interfaces, Launch Vehicle Avionics, FPGA Prototyping and Design Verification.
Satellite Payload Signal Processing
The RTAX2000DL-1CQ352B fits satellite payload processing where up to 120 DSP mathblocks perform 18-bit x 18-bit MACs at 125 MHz, enabling onboard FFTs, FIR filtering, and image compression that cut downlink bandwidth before transmission. Placed as the main payload processing element between high-speed ADCs and the telemetry formatter, its antifuse fabric is immune to configuration upsets, eliminating the SEFI failure class that affects SRAM FPGAs in orbit. The 540 kbits of embedded SRAM with EDAC protects buffering against single-event upsets, and the single-chip live-at-power-up operation removes the need for external configuration storage - a reliability and board-space win. Designers must budget power for DSP-heavy modes, as high MAC utilization at 125 MHz increases core current within the 1.425-1.575V supply range.

Spacecraft On-Board Data Handling (OBDH)
For spacecraft command and data handling, the RTAX2000DL-1CQ352B provides 2 million gates of glue-free integration for bus controllers (MIL-STD-1553, SpaceWire, CAN), memory controllers, and housekeeping functions in one hermetic CQFP-352 device. Its embedded SRAM with FIFO control logic implements telemetry buffers without external FIFO chips, while the 0.930 ns combinatorial delay supports fast state machines and time-tagging at moderate clock rates. Because the antifuse configuration is programmed once and lives at power-up, the OBDH controller is operational milliseconds after switch-on with no configuration memory to fail - a key single-point-failure removal for avionics. Designers should segment clocks across the available clock resources to isolate the critical processor interface domain from slower housekeeping logic.
추천
Telemetry and Telecommand (TM/TC) Controllers
TM/TC front-ends benefit from the RTAX2000DL-1CQ352B's combination of 166 input and 166 output terminals and CMOS 1.5V core, allowing direct interfacing to redundant receiver chains, decoders, and formatting logic inside one package. EDAC-protected embedded memory secures command logs and telemetry frames against upsets, and the deterministic antifuse fabric avoids the reconfiguration pauses that SRAM devices can exhibit after an error. In a typical chain, the FPGA sits between the RF receiver baseband outputs and the spacecraft bus controller, implementing frame synchronization, cyclic redundancy checks, and rate adaptation. Because the package is ceramic and hermetic, it is compatible with standard flight-qualification flows including screening per program source control drawings, easing integration into legacy TM/TC hardware baselines.

Radiation-Exposed Sensor Interfaces
Scientific instruments on interplanetary probes and Earth-observation satellites require front-end logic that keeps functioning under radiation: the RTAX2000DL-1CQ352B's 300 krad (Si) functional TID rating and 200 krad parametric rating cover multi-year missions beyond low Earth orbit. Its DSP mathblocks (18x18 at 125 MHz) can perform correlated double sampling, digital filtering, and histogramming of imager or spectrometer data streams directly at the sensor head. The 166 I/O terminals accommodate multi-channel CCD/CMOS imager interfaces with parallel data capture, while embedded EDAC-protected SRAM buffers frames for compression or downlink. Designers should place the FPGA close to the sensor to minimize analog trace length, and route sensitive clock inputs away from high-swing I/O banks per the manufacturer datasheet layout guidance.

Launch Vehicle Avionics
Launch environments impose extreme vibration plus radiation exposure during ascent through the Van Allen belts; the RTAX2000DL-1CQ352B addresses both with a hermetic CQFP-352 ceramic package and antifuse fabric that cannot lose configuration under particle strike. Live-at-power-up operation suits flight computers and stage-separation controllers where no reconfiguration window exists. The device's 2-million-gate capacity integrates redundant-voting logic, discrete I/O acquisition, and safety-critical interlocks, while the 0.930 ns maximum combinatorial delay supports fast fault-detection comparators. Designs should implement triple-modular redundancy in the fabric for single-event-effect mitigation and use the chip-wide routing resources for redundant clock distribution. Availability planning is essential: order flight lots well ahead of the integration campaign given long space-grade lead times.
추천
FPGA Prototyping and Design Verification
Because the RTAX2000DL-1CQ352B is one-time-programmable, flight teams prototype against the RTAX architecture using the Aldec ACT-H3Ki-CQ352 adaptor, which mates a flash-based Microchip ProASIC3E device to a CQ352 footprint with matching power supply and JTAG programming. This flow allows designers to verify RTL, timing, and interface behavior before irreversibly programming flight antifuse devices, drastically reducing costly flight-lot loss. The adaptor is powered either through the CQ352 leads or an onboard connector, and XAIPART recommends a full hardware regression - including power sequencing at 1.425V minimum core voltage - before committing the RTAX2000DL-1CQ352B. Budget the prototyping phase into program schedules, as simulation-only sign-off has repeatedly proven insufficient for antifuse timing closure in high-utilization designs.

설계 노트
The RTAX2000DL-1CQ352B uses one-time-programmable antifuse technology - a programmed device can never be reprogrammed or reused. Never program flight units with unverified bitstreams. The standard mitigation is prototyping on the Aldec ACT-H3Ki-CQ352 adaptor (flash-based ProASIC3E, footprint- and power-compatible with RTAX CQ352) and completing full regression before generating flight programming files. Program at least one spare device per flight lot to cover handling damage during programming and post-programming inspection.
Supply the core at 1.5V nominal within 1.425V to 1.575V per Microchip USA product data. Estimated: a fully utilized 2M-gate fabric running DSP mathblocks at 125 MHz draws significantly more core current than control-logic designs, so size the core rail with margin above your Libero power-analysis estimate and verify with brown-out testing at 1.425V. Power I/O banks according to the datasheet bank assignments; never exceed the per-bank current ratings, and decouple each supply pin pair with 0.1 uF ceramics placed close to the package leads.
With 166 input and 166 output terminals in a CQFP-352, simultaneous switching output (SSO) noise is the dominant signal-integrity risk. Group high-toggle-rate outputs across multiple ground-reference banks, limit per-bank drive strength in Libero, and use series termination on clock and strobe outputs. Hermetic CQFP leads are longer than BGA balls, so model lead inductance in IBIS simulations for interfaces above roughly 50 MHz. Follow the RTAX-S/SL datasheet clock-routing guidance for the segmentable clock network.
