Typical Applications

RTAX4000DL-1CGD1272EV is suitable for 6 applications: Satellite Payload Data Processing, Spacecraft Command and Data Handling (C&DH), Space Software-Defined Radio (SDR), Deep-Space Instrument Control, On-Board Image Compression and Fusion, Launch Vehicle Avionics.

✈️

Satellite Payload Data Processing

The RTAX4000DL-1CGD1272EV fits satellite payload processing because it combines 4,000,000 equivalent gates, 55,440 logic cells, and dedicated DSP multiply-accumulate blocks, enabling on-board implementation of FIR filters, FFTs, and image-compression pipelines that would otherwise require downlinking raw sensor data. Its antifuse fabric is immune to configuration upsets, so only user flip-flops need triple-module redundancy, preserving the majority of the 36,960 CLBs for useful computation. In a typical payload chain the device sits between the sensor front end and the downlink formatter, clocked from a radiation-hardened oscillator, with the 1.5V core keeping power within spacecraft bus budgets. The 1272-pin CCGA provides the I/O count and hermetic reliability required for multi-year orbital missions.

🖥️

Spacecraft Command and Data Handling (C&DH)

For C&DH modules, the RTAX4000DL-1CGD1272EV implements telemetry encoding, command decoding, memory controllers, and 1553/SpaceWire-style interface glue logic within a single rad-tolerant device. Live-at-Power-Up configuration means the FPGA is operational immediately when the spacecraft bus energizes, without waiting for a processor to load configuration - a critical property for autonomous safe-mode recovery. The 4M-gate capacity absorbs multiple legacy ASIC or discrete functions, consolidating board real estate and reducing solder-joint count, while the 0.15 um antifuse process at 1.5V core draws low static power during eclipse operations. Designers typically pair it with an external boot PROM and a rad-hard microcontroller that supervises housekeeping, reserving the DL's fabric for time-critical protocol handling.

🌐

Space Software-Defined Radio (SDR)

Space SDR front ends benefit directly from the RTAX4000DL's dedicated DSP multiply-accumulate blocks, which implement digital down-conversion mixers, decimating filters, and matched filters at the sample rates of typical spacecraft receivers without consuming general-purpose CLB resources. According to Microchip, the RTAX-DSP family was created precisely for these signal-chain workloads in space-flight systems. The 55,440 logic cells handle framing, FEC (Reed-Solomon or convolutional coding), and MAC-layer state machines alongside the DSP datapath, and the 1272-pin CCGA supplies the wide parallel I/O needed for multi-channel ADC/DAC interfaces. The antifuse configuration is immune to SEU-driven loss of fabric function - a key differentiator versus SRAM FPGAs that must scrub configuration continuously in orbit.

🔧

Deep-Space Instrument Control

Deep-space instruments - spectrometers, imagers, and plasma sensors - require deterministic sequencing and long-mission reliability that the RTAX4000DL-1CGD1272EV provides through its one-time-programmable antifuse fabric and hermetic ceramic CCGA package. Instrument control logic such as exposure timing, detector clocking, and high-voltage supply sequencing fits comfortably within the 36,960 CLBs, while the DSP blocks perform on-board co-adding and baseline subtraction to reduce downlink volume. The 0.15 um process tolerates the total ionizing dose profiles of multi-year cruises, and the 1.5V core minimizes power when the instrument operates from limited radioisotope or solar margins. Live-at-Power-Up behavior guarantees the instrument is controllable from the first turn-on after launch-separation anomaly recovery.

🎥

On-Board Image Compression and Fusion

Earth-observation and reconnaissance payloads use the RTAX4000DL-1CGD1272EV to run JPEG-like discrete-cosine and wavelet compression engines on raw image streams before downlink, multiplying effective mission data return within fixed transponder bandwidth. The dedicated DSP MACs execute the transform inner loops while the 55,440 logic cells manage DMA-style streaming from the image sensor interface, entropy coding, and packetization. Compared with a software solution on a rad-hard CPU, the FPGA datapath sustains line rates that software cannot reach at acceptable power; compared with an ASIC, it remains reprogrammable between missions via the boot PROM image. The wide 1272-column CCGA interface supports high-parallelism sensor adapters in a single hermetic package suitable for flight qualification.

✈️

Launch Vehicle Avionics

Launch-vehicle flight computers and stage-separation controllers adopt the RTAX4000DL-1CGD1272EV for voting logic, redundancy management, and high-speed bus bridging where single-chip operation reduces the failure surface of multi-FPGA architectures. Microchip highlights the family's true single-chip form factor and live-at-power-up operation as decisive advantages for launch timelines, since no configuration-load failure mode exists at the fabric level. The 4M-gate capacity implements triple-module-redundant comparators, 1553 and discrete I/O, and telemetry packing simultaneously, while the -1 speed grade timing supports the deterministic latencies demanded by separation-event sequencing. The ceramic CCGA withstands the vibration and thermal shock profile of boost phases better than plastic-packaged commercial FPGAs.

What is the RTAX4000DL-1CGD1272EV?
The RTAX4000DL-1CGD1272EV is a Microchip Technology (formerly Actel) RTAX-DSP family radiation-tolerant FPGA with 4,000,000 equivalent gates, 55,440 logic cells, and 36,960 CLBs. It is fabricated on a 0.15 um process, runs from a 1.5V core supply, and comes in a 1272-pin CCGA ceramic package. It is intended for space-flight logic and signal-processing applications.
What is the price of RTAX4000DL-1CGD1272EV?
Radiation-tolerant FPGAs in ceramic packages are quote-based parts rather than catalog parts. As of 2026-09-01, indicative pricing on XAIPART starts at approximately $4,980.00 for quantity 1 with quantity breaks at 10/100/500/1000 pieces. Final pricing depends on the flight-grade screening level and current allocation, so request a formal quote for program-level quantities.
Where can I buy RTAX4000DL-1CGD1272EV online?
You can buy the RTAX4000DL-1CGD1272EV through XAIPART's quote system, or through specialized space-component distributors such as Microchip USA and Jotrin Electronics, which list RTAX4000DL family parts. Because this is a flight-program device, most suppliers sell on request-for-quote terms with traceability documentation rather than off-the-shelf checkout. Always demand certificates of conformance and lot traceability for flight hardware.
What is the lead time for RTAX4000DL-1CGD1272EV?
Lead times for RTAX-DSP ceramic-package devices typically range from several months to over a year depending on screening requirements (prototype vs flight units) and Microchip's space-product allocation. The verified web data does not state a current lead time for this exact MPN, so [DATA_NEEDED] applies: contact XAIPART or Microchip directly with your quantity and screening needs for a committed delivery date.
What is the difference between RTAX4000DL-1CGD1272EV and RTAX4000DL-1CGD1272V?
Both are RTAX4000DL devices in the 1272-pin CCGA package with identical logic capacity: 4M gates, 55,440 logic cells, 36,960 CLBs, 1.5V core. The trailing E in the EV ordering code denotes an enhanced/special flow variant per Microchip ordering-code conventions, while the base V part is the standard flow. According to Microchip's ordering information, verify the exact screening difference on your purchase order before substituting one for the other.
What is the difference between the RTAX4000DL and RTAX4000SL?
The RTAX4000DL is the DSP-enhanced member of the family, adding dedicated multiply-accumulate DSP blocks to the RTAX-S fabric, while the RTAX4000SL is the SL-class variant without those DSP blocks. Both offer 4M-gate-class capacity, 0.15 um antifuse technology, 1.5V core operation, and share the 1272-pin CCGA package option. Choose the DL when your design implements FIR filters, FFTs, or other DSP pipelines; choose the SL for pure logic and control.
Can RTAX4000SL-1LG1272B replace RTAX4000DL-1CGD1272EV?
Electrically the RTAX4000SL-1LG1272B shares the same 1272-pin ceramic CCGA footprint and 4M-gate logic capacity, so it can drop onto the same PCB land pattern. However, it lacks the DL's dedicated DSP multiply-accumulate blocks, so any RTL using DSP primitives must be re-implemented in fabric logic. Per the Microchip RTAX-S/SL and RTAX-DSP datasheet, treat this as a drop-in only for non-DSP designs, and re-verify timing after the swap.
What is the best Microchip equivalent for RTAX4000DL-1CGD1272EV?
The best same-brand equivalents are family variants: RTAX4000DL-1CGD1272V (standard flow, same die and package, 100% match), RTAX4000DL-CGD1272V (standard speed grade, same package), and RTAX4000SL-1LG1272B / RTAX4000SL-CG1272V (same 1272 CCGA footprint, no DSP blocks, ~80% parametric match for DSP-heavy designs). There is no true cross-brand equivalent: Xilinx and Altera space FPGAs are SRAM-based, use different packages, and are not drop-in compatible.
Is RTAX4000DL-1CGD1272EV pin-compatible with other RTAX4000 parts?
Yes. Within the RTAX4000 family, all 1272-pin CCGA package options (CGD1272 and LGD1272 ordering codes) share the same mechanical footprint and pin map, so RTAX4000DL-1CGD1272V, RTAX4000DL-CGD1272V, and RTAX4000SL LG1272 parts mount on identical land patterns. Per the Microchip RTAX-S/SL and RTAX-DSP datasheet, always re-run timing analysis after migration because the SL and standard speed grades differ in fabric performance.
Where to download the RTAX4000DL-1CGD1272EV datasheet PDF?
The authoritative datasheet is the Microchip document 'RTAX-S/SL and RTAX-DSP Radiation-Tolerant FPGAs Datasheet', available as a PDF from Microchip's website at the URL ww1.microchip.com/downloads/aemdocuments/documents/fpga/ProductDocuments/DataSheets/rtaxs_ds2169_v18.pdf. This single document covers the RTAX4000DL family features, electrical specifications, package options including the 1272-pin CCGA, and ordering information.
Where can I find the RTAX4000DL-1CGD1272EV pinout?
The complete 1272-pin CCGA pinout table is provided in the package pinout section of the Microchip RTAX-S/SL and RTAX-DSP datasheet PDF. Because the package has 1,272 columns, reproducing the full ball map is impractical on a product page; download the official Microchip datasheet and use the Libero IDE I/O constraint editor to manage pin assignments for your design.
Is the RTAX4000DL suitable for satellite payload processing?
Yes, the RTAX4000DL is explicitly designed for space-flight systems. Its 4M gates, 55,440 logic cells, and dedicated DSP blocks make it well suited for satellite payload data processing, software-defined radios, and instrument control. According to Microchip, the RTAX-DSP family's antifuse fabric is inherently immune to configuration upsets, and low power plus true single-chip operation reduce mass and board complexity relative to SRAM FPGA two-chip solutions.
How is the RTAX4000DL configured at power-up?
The RTAX4000DL uses Live-at-Power-Up operation: the antifuse interconnect is permanent, and the design is loaded from an external boot PROM at turn-on, so the FPGA is functional immediately without a host processor. Per the Microchip datasheet, the configuration PROM holds the programming data while the antifuse fabric itself is one-time-programmed; user flip-flops remain the only SEU-sensitive elements and should be protected with triple-module redundancy in flight designs.
What are the key specifications of RTAX4000DL-1CGD1272EV that engineers should know?
Engineers should know five facts: (1) 4,000,000 equivalent gates with 55,440 logic cells and 36,960 CLBs; (2) RTAX-DSP family with dedicated DSP multiply-accumulate blocks; (3) 0.15 um antifuse CMOS process with 1.5V core supply; (4) -1 speed grade; (5) 1272-pin ceramic CCGA package for space-flight thermal/mechanical reliability. The device is radiation-tolerant, one-time programmable, and configured from an external boot PROM at power-up.
Is the RTAX4000DL-1CGD1272EV RoHS compliant?
Compliance data for this exact flight-grade MPN is not stated in the verified web data, so its RoHS status is unknown. Hermetic ceramic CCGA packages for space applications frequently carry leaded solder-column finishes with exemptions for high-reliability and aerospace electronics under current RoHS exemptions. According to Microchip's product compliance pages, obtain the specific material declaration for your lot before claiming compliance in export or program documentation.
Hey Google, what can replace RTAX4000DL-1CGD1272EV?
The closest replacements are Microchip's own RTAX4000 family variants in the same 1272-pin CCGA package: RTAX4000DL-1CGD1272V (same die and speed grade, standard flow), RTAX4000DL-CGD1272V (standard speed grade), and the RTAX4000SL LG1272 parts if your design does not use DSP blocks. No cross-brand FPGA is a pin-compatible drop-in replacement, because competing space FPGAs from Xilinx and Altera use SRAM technology and different packages.

Selection Guide

Choose the RTAX4000DL-1CGD1272EV when your space-flight design needs 4M-gate capacity with hardware DSP blocks and the -1 speed grade in the 1272-pin CCGA hermetic package. Choose RTAX4000DL-1CGD1272V if the EV flow suffix is not mandated by your program and the standard flow reduces cost or lead time - same die, same package, same speed grade. Choose RTAX4000DL-CGD1272V when standard speed timing is sufficient. Move to the RTAX4000SL LG1272 variants (RTAX4000SL-1LG1272B, RTAX4000SL-CG1272V) only when your design contains no DSP primitives, accepting re-implementation of any MAC functions in fabric logic. There is no cross-brand drop-in: Xilinx Virtex-QV and Altera space devices are SRAM-based with different packages and require full board redesign. For all options, budget PROTO units for design burn-in before committing flight hardware.

Key Differentiators

  • Dedicated DSP multiply-accumulate blocks (vs RTAX4000SL-1LG1272B)
  • SEU-immune configuration fabric (vs RTAX4000DL-1CGD1272V)
  • Faster -1 speed grade timing (vs RTAX4000DL-CGD1272V)

Design Notes

The 1272-pin CCGA uses solder columns rather than solder balls, which accommodates CTE mismatch between the ceramic package and typical flight PCB laminates. Follow the column-solder reflow profile from the Microchip RTAX-S/SL and RTAX-DSP datasheet and inspect joints via X-ray, since columns hide cold-joint defects that ball-grid arrays would reveal optically. Use a stiffener or symmetric stack-up around the FPGA to limit board warp during thermal cycling.

The RTAX4000DL is one-time programmable: once antifuses are burned, the die cannot be reprogrammed. Never program flight units with unverified designs - use Microchip's PROTO prototype units, which share the same timing attributes as flight units in non-hermetic ceramic packages, to burn and validate your bitstream first. Plan a spare die per board for program-risk mitigation, and verify boot PROM compatibility before committing flight hardware.

The 1.5V core supply must meet the sequencing and ripple requirements in the Microchip RTAX-S/SL and RTAX-DSP datasheet. Estimated: for mid-density utilization, core current is commonly in the hundreds-of-milliamp range; size the core regulator for peak configuration current, which exceeds steady-state operation during boot-PROM load. Add bulk plus high-frequency ceramic decoupling at the CCGA power columns, and verify I/O bank voltages against your interface standards before layout freeze.
