Typical Applications
RTAX2000DL-CQ352E is suitable for 6 applications: Satellite Payload Data Processing, Spacecraft Command and Data Handling, Telemetry and Telecommand Encoding, Sensor Interface and Digital Signal Processing, Avionics and Platform Control Electronics, FPGA Prototyping and Design Migration.
Satellite Payload Data Processing
The RTAX2000DL-CQ352E fits payload data-processing chains that need millions of gates of deterministic logic under radiation. Its 19,712 CLBs implement channelizers, forward error correction, and compression engines, while embedded SRAM blocks with built-in FIFO control absorb data-rate mismatches between high-speed front ends and downlink formatters. The antifuse fabric is live at power-up and immune to configuration upset, so the payload begins operating the instant spacecraft power is applied without a configuration readback sequence. In a typical implementation the FPGA sits between the ADC front end and the telemetry formatter, clocked from segmentable on-chip clock resources to isolate processing domains. Power per gate is far lower than SRAM FPGAs of equivalent capacity, which matters because payload electronics budgets are frequently limited to a few watts total. The single-chip antifuse form factor also eliminates the configuration PROM, reducing board area, parts count, and a common SEU failure point on multi-year orbital missions.

Spacecraft Command and Data Handling
Spacecraft C&DH units require control logic that starts instantly after reset and survives total ionizing dose over mission life, which is exactly where the RTAX2000DL-CQ352E is positioned. Its 2M-gate fabric implements the spacecraft bus controller, memory-error-corrected mass-storage interfaces, and MIL-STD-1553 or SpaceWire style protocol bridges, while the 166 input and 166 output user terminals of the CQFP-352 package provide ample parallel interface capability in a hermetic 48 mm x 48 mm ceramic body. Because configuration is stored in antifuse elements, there is no configuration memory to be corrupted by single-event upset, so the C&DH state machine resumes from hardware immediately at power-up - a key advantage over SRAM FPGAs that must reload configuration from external flash. Segmentable clocks let designers run housekeeping logic at low frequency for power savings while keeping critical interfaces fast, and chip-wide highway routing simplifies distributing control signals across the fabric.
Recommended
Telemetry and Telecommand Encoding
Telemetry encoders and telecommand decoders benefit from the RTAX2000DL-CQ352E combination of deterministic timing, embedded FIFO memory, and radiation tolerance. The device implements CCSDS-class framing, convolutional or RS-style encoding pipelines, and rate adaptation entirely in hardware with cycle-accurate timing that software approaches cannot guarantee. Embedded SRAM blocks with built-in FIFO control logic buffer telemetry frames between the formation stage and the modulator, decoupling clock domains without external FIFO chips - important in a hermetic CQFP-352 assembly where every extra component adds screening cost. The D speed grade delivers adequate performance for typical telemetry rates while minimizing dynamic power, and the live-at-power-up antifuse fabric means the encoder is operational before the first downlink pass completes startup. Designers should prototype the whole chain on the footprint-compatible adaptor flow before programming, since the antifuse array is one-time programmable.
Recommended
Sensor Interface and Digital Signal Processing
On-board instruments - imagers, spectrometers, and particle detectors - need real-time DSP close to the sensor, and the RTAX2000DL-CQ352E addresses this as an RTAX-DSP-class device. Its 2M gates accommodate multi-channel FIR filters, correlators, and CIC decimation chains, while embedded SRAM with FIFO control stores coefficient sets and sample windows on chip. The 166 user inputs accept parallel sensor data buses directly, and segmentable clocks allow the acquisition front end to run fast while post-processing blocks run slower and cooler. Radiation tolerance is the decisive factor: the antifuse configuration cannot be upset in orbit, and the fabric is characterized for the dose environments of LEO through deep-space missions. Because the part is one-time programmable, the recommended flow is to prototype the full signal chain on a footprint-compatible commercial Axcelerator device via an adaptor board, convert the EDIF netlist and pinout, and only then commit the flight part.

Avionics and Platform Control Electronics
Launch-vehicle and spacecraft avionics modules use the RTAX2000DL-CQ352E where deterministic, instantly-on glue logic and control sequencing are required in a radiation environment. The hermetic ceramic CQFP-352 package, 48 mm x 48 mm with 0.50 mm pitch, mounts reliably on high-reliability circuit card assemblies and withstands the thermal cycling of launch and eclipse transitions better than plastic-packaged devices. With 19,712 CLBs, one device typically replaces dozens of radiation-tolerant ASSP and discrete logic parts, cutting board area, solder joints, and screening burden. The antifuse fabric starts operating within microseconds of power application, which matters for sequencers that must gate power supplies during spacecraft power-up before software is running. Chip-wide highway routing distributes reset and mode signals with low skew, and the segmentable clock structure supports independent timing domains for actuator interfaces versus housekeeping telemetry.

FPGA Prototyping and Design Migration
The RTAX2000DL-CQ352E is the target device in Microchip's documented prototyping methodology for space designs: logic is developed and verified on a footprint-compatible commercial device mounted on an adaptor board (such as the Aldec ACT-H3Ki-CQ352 for the CQ352 footprint), then migrated via an EDIF netlist and pinout converter to the RTAX antifuse part. The CQ352 package's power and footprint compatibility with the adaptor preserves the final flight PCB layout during development, so timing, I/O assignment, and board-level signal integrity are validated on the exact footprint. Because the antifuse array is one-time programmable, this adaptor-based flow is not optional - it is the recommended way to guarantee the flight design works before committing an expensive, long-lead-time space-grade device. Teams commonly keep prototype boards in circulation for regression testing while flight lots of RTAX2000DL-CQ352E are on factory order.

Key Differentiators
- Antifuse fabric is live at power-up and immune to configuration upset (vs RTAX4000DL-CQ352E)
- D speed grade offers adequate timing at lower cost (vs RTAX2000DL-1CQ352E)
- 2M gates in a hermetic 48x48 mm ceramic CQFP with 332 user I/O (vs RTAX250SL-CQ352V)
Design Notes
RTAX devices are one-time programmable antifuse FPGAs - programming errors cannot be corrected in the field. Follow Microchip's documented prototyping methodology: verify the design on a footprint-compatible adaptor board with a commercial Axcelerator device, then migrate using the EDIF netlist and pinout converter before committing the RTAX2000DL-CQ352E. Never program the flight part until timing closure, I/O assignment, and board-level checks are complete, since each failed device is a full cost and lead-time loss.
The CQFP-352 package is a 48 mm x 48 mm ceramic body with 0.50 mm terminal pitch and gull-wing leads. Use a matching 352-pad footprint with solder-defined pads and inspectable heel fillets for space-grade workmanship standards. Plan the land pattern for the metal-sealed ceramic body's thermal expansion relative to the PCB - underfill or compliant mounting may be needed for severe thermal-cycling missions. Keep high-speed I/O routed with controlled impedance and reference solid planes beneath the 0.50 mm-pitch lead rows.
Power planning must account for both core and I/O supplies per the RTAX-S/SL datasheet; the DL variant's I/O banking supports the voltage standards required by the spacecraft bus interfaces. Estimate dynamic power in Libero using the actual design activity rates rather than worst-case toggle - overestimating leads to oversized power converters on power-limited spacecraft. Verify the exact supply voltages and sequencing requirements in the manufacturer datasheet (rtaxs_ds2169) for your orderable flow before finalizing the power tree.
Compliance Information
Space-grade hermetic ceramic CQFP packages are frequently covered by RoHS exemptions and finish options vary by order flow; verify with the Microchip product page for RTAX2000DL and request material declarations from the distributor. AEC-Q100 is not applicable to this space-flow product family.
