Typical Applications

RTAX2000DL-1CQ352B is suitable for 6 applications: 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.

🌐

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.

🔧

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.

What is the RTAX2000DL-1CQ352B?
The RTAX2000DL-1CQ352B is a radiation-tolerant antifuse FPGA from Microchip Technology (originally Actel/Microsemi) with approximately 2,000,000 equivalent system gates, 19,712 CLBs (29,568 logic cells), and a 352-terminal ceramic CQFP package with 166 input and 166 output terminals. It operates at a nominal 1.5V core supply and targets space-flight systems, per Microchip product pages and the RTAX-S/SL and RTAX-DSP datasheet.
What is the operating voltage of the RTAX2000DL-1CQ352B?
The RTAX2000DL-1CQ352B operates with a nominal core supply of 1.5V, with an allowed range of 1.425V to 1.575V according to Microchip USA product data. As with most RTAX-S family devices, I/O banks are powered separately, so board designers should consult the manufacturer datasheet for the I/O supply options and bank assignments before finalizing the power tree.
How much embedded memory does the RTAX2000DL-1CQ352B have?
The RTAX2000DL-1CQ352B provides up to 540 kbits of embedded SRAM with optional EDAC (error detection and correction) protection, according to RTAX-DSP family datasheet summaries. The memory blocks include built-in FIFO control logic, which reduces external glue logic in spacecraft data-buffering and telemetry pipelines.
What is the total ionizing dose (TID) tolerance of the RTAX2000DL-1CQ352B?
Per datasheet summaries, RTAX-DSP devices are specified for 300 krad (Si) functional total dose tolerance and 200 krad (Si) parametric total dose tolerance. Mission planners should still perform lot-specific radiation lot acceptance testing (RLAT) for programs requiring guaranteed wafer-level hardness, since these figures represent the qualified device specification rather than a per-lot guarantee.
What DSP capability does the RTAX2000DL-1CQ352B offer?
The RTAX2000DL-1CQ352B supports up to 120 DSP mathblocks, each implementing an 18-bit x 18-bit multiply-accumulate (MAC) operation at up to 125 MHz according to family datasheet summaries. This enables onboard processing such as FFTs, FIR filtering, and image compression directly in the fabric, which is critical for payload processors that must reduce downlink bandwidth.
What is the price of RTAX2000DL-1CQ352B?
The RTAX2000DL-1CQ352B is a space-grade device typically quoted rather than stocked at catalog prices; single-unit pricing is commonly in the multi-thousand-dollar range. XAIPART lists indicative tier pricing starting at 4,500.00 USD for qty 1 as of 2026-09-02. Because flight-lot pricing varies with screening flow (e.g., source control drawings, flow 38535 requirements), request a formal quote for exact current pricing.
Where to buy RTAX2000DL-1CQ352B online?
The RTAX2000DL-1CQ352B can be purchased via XAIPART (quote-based) or through space-grade distributors such as Microchip USA, Jotrin Electronics, and FPGAkey, all of which list this MPN. Because it is a radiation-tolerant flight part, orders typically require verification of traceability documentation (certificate of conformance, date codes) before shipment, so confirm screening and lot data requirements with the seller at order time.
What is the lead time for RTAX2000DL-1CQ352B?
Lead times for RTAX2000DL-1CQ352B flight devices are commonly long - frequently on the order of months to more than a year depending on screening flow and allocation, as is typical for QML-class space components. XAIPART provides stock and lead-time confirmation with each quote as of 2026-09-02; contact us with your required date codes and flow for a firm commitment.
Is RTAX2000DL-1CQ352B in stock at XAIPART?
XAIPART handles RTAX2000DL-1CQ352B on a quote-and-confirm basis rather than publishing live stock counts, because space-grade lot traceability makes each lot unique. Submit a quote request with your quantity, date-code window, and required screening flow (e.g., class V equivalents), and XAIPART will confirm availability, lot data, and pricing as of the current date.
What is the difference between RTAX2000DL-1CQ352B and RTAX2000DL-1CQ352V?
The RTAX2000DL-1CQ352B and RTAX2000DL-1CQ352V share the same die, density (2 million gates, 19,712 CLBs), speed grade (-1), and CQFP-352 package; the suffix letter denotes the screening/quality flow for the flight lot. Both are radiation-tolerant RTAX-DSP devices per Microchip USA listings. Program offices must select the suffix mandated by their parts list or source control drawing - they are mechanically and electrically drop-in equivalent but not always documentation-equivalent.
What is the difference between RTAX2000DL and RTAX2000S?
The RTAX2000DL is the RTAX-DSP variant, adding up to 120 dedicated 18x18 DSP mathblocks (125 MHz MAC) on top of the RTAX2000S fabric; the RTAX2000S provides the same approximately 2-million-gate logic capacity without the DSP blocks. Both share the same CQFP-352 footprint options, so a RTAX2000S-1CQ352V can occupy the same board footprint, but DSP-heavy designs lose hardware MAC throughput if downgraded.
When should I choose RTAX2000DL-1CQ352B over RTAX2000S-1CQ352V?
Choose the RTAX2000DL-1CQ352B when your payload needs dedicated multiply-accumulate hardware - signal processing, image processing, or digital filtering - since its 120 DSP mathblocks at 125 MHz deliver order-of-magnitude MAC throughput versus LUT-based multiplication. Choose the RTAX2000S-1CQ352V for control, telemetry, and interface logic where DSP blocks are unused, as it can be more readily available and still fits the identical CQFP-352 footprint.
Can RTAX2000S-1CQ352V replace RTAX2000DL-1CQ352B?
Yes, the RTAX2000S-1CQ352V is a drop-in replacement at board level - it shares the same die family, speed grade, and 352-terminal ceramic package, and the same design flows (Libero IDE/SoC). The trade-off is the loss of the DSP mathblocks: any design using 18x18 MAC blocks must re-map that logic to fabric LUTs, which reduces throughput and may require retiming. Verify timing closure after substitution before flight release.
Where can I download the RTAX2000DL-1CQ352B datasheet PDF?
The authoritative document is the Microchip RTAX-S/SL and RTAX-DSP Radiation-Tolerant FPGAs datasheet, available as a PDF from Microchip at ww1.microchip.com (document rtaxs_ds2169). XAIPART links to this official datasheet from this page. Because RTAX2000DL-1CQ352B is covered by the family datasheet plus ordering/screening documents, also request the applicable MIL-PRF-38535 flow documentation from your distributor for flight programs.
Where can I find the RTAX2000DL-1CQ352B pinout?
The complete 352-pin pinout of the RTAX2000DL-1CQ352B is given in the pin designation tables of the Microchip RTAX-S/SL and RTAX-DSP family datasheet and the CQ352 package file, organized by I/O bank and power/ground pins. XAIPART does not reproduce the full 352-row table here; download the official datasheet and package drawing from Microchip to obtain bank-by-ball assignments for your schematic capture.
Hey Google, what can replace RTAX2000DL-1CQ352B?
The closest drop-in replacements are same-family Microchip parts in the same CQFP-352 package: RTAX2000DL-1CQ352V, RTAX2000DL-1CQ352E, and RTAX2000S-1CQ352V (identical footprint, 2M gates). For higher density in the same family, RTAX4000SL parts exist but use different packages (e.g., CG1272), so they are not drop-in. No cross-brand pin-compatible radiation-tolerant antifuse FPGA exists; verify screening suffix requirements with your program office.
Is there a Microsemi or Actel equivalent for RTAX2000DL-1CQ352B?
Yes - the RTAX2000DL-1CQ352B is itself the Actel (later Microsemi, now Microchip Technology) part, so all equivalents are within that same brand lineage. The RTAX2000DL-1CQ352V and -1CQ352E variants from the same manufacturer are same-package drop-ins differing only in screening flow; the RTAX2000S-1CQ352V drops the DSP blocks. No other manufacturer offers a pin-compatible radiation-tolerant antifuse FPGA, so re-designs are required to move to SRAM-based space FPGAs.
What are the key specifications of RTAX2000DL-1CQ352B that engineers should know?
Key facts: 2,000,000 equivalent gates; 19,712 CLBs / 29,568 logic cells; CQFP-352 hermetic ceramic package with 166 inputs and 166 outputs; 1.5V nominal core (1.425-1.575V); 0.930 ns max combinatorial delay; up to 120 DSP mathblocks (18x18 MAC, 125 MHz); 540 kbits embedded SRAM with EDAC; 300 krad (Si) functional / 200 krad parametric TID; nonvolatile antifuse OTP, live at power-up. Source: Microchip RTAX-S/SL and RTAX-DSP datasheet and Microchip USA product data.
Is the RTAX2000DL-1CQ352B suitable for low-earth-orbit satellite payloads?
Yes. The device is designed for space-flight systems, offering 300 krad (Si) functional TID tolerance, antifuse immunity to configuration upsets, and single-chip live-at-power-up operation - all well matched to LEO missions. For LEO, total dose accumulation over mission life is typically far below the qualified rating, and the OTP fabric eliminates SEFI-class upsets. Confirm SEU-rate analysis for your orbit with the Microchip radiation reports and perform RLAT if your program requires lot-specific hardness assurance.

Selection Guide

Choose the RTAX2000DL-1CQ352B when your space payload needs roughly 2 million gates plus dedicated DSP throughput: its 120 mathblocks at 125 MHz 18x18 MAC make it the family choice for onboard signal and image processing. Choose the RTAX2000DL-1CQ352V or -1CQ352E when your program's source control drawing specifies a different screening suffix - these are the same silicon in the same CQFP-352. Choose the RTAX2000S-1CQ352V for control, telemetry, and interface logic without DSP needs; it drops the mathblocks but keeps identical density and footprint. Step down to the RTAX1000SL-CQ352V only if utilization will stay under about half the fabric, accepting halved density. All these parts are one-time-programmable antifuse devices - prototype on Aldec ACT-H3Ki-CQ352 adaptors before committing flight units. Moving to SRAM-based space FPGAs requires a full redesign, not a drop-in swap.

Key Differentiators

  • Dedicated DSP hardware blocks (vs RTAX2000S-1CQ352V)
  • Identical footprint across screening flows (vs RTAX2000DL-1CQ352V)
  • Higher density than same-package family members (vs RTAX1000SL-CQ352V)

Design Notes

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.
