RTAX2000S-1CQ256PROTO - 2M-Gate Rad-Tolerant FPGA Proto | Microchip
MPN: RTAX2000S-1CQ256PROTO ✓ AktifRTAX2000S-1CQ256PROTO Genel Bakış
A radiation-tolerant FPGA is a programmable logic device qualified for space-flight environments, where high-energy particles cause single-event upsets (SEU) and total ionizing dose (TID) degradation. Within the power-management hierarchy of spacecraft avionics, these devices sit above general-purpose FPGAs in reliability and are the direct descendants of the commercial Microsemi (Actel) Axcelerator architecture, retaining library compatibility with it.
Key features of the RTAX2000S family include nonvolatile, highly reliable antifuse technology that is live-at-power-up (no configuration flash or external boot device), up to 540 kbits of embedded SRAM with optional EDAC protection, and SEU-hardened registers that reduce or eliminate the need for triple-module redundancy (TMR). The family is specified for total dose of 300 krad (functional) and 200 krad (parametric), with SEU rates below 1E-10 errors per bit-day on flight-grade variants.
Architecturally, the RTAX2000S is based on the Axcelerator fabric: fine-grained logic modules, segmentable clock resources, chip-wide routing, and embedded FIFO control logic. Note that although RTAX-S devices are library-compatible with Axcelerator, internal timing differs significantly, which is exactly why Microchip application note AC170 recommends prototyping on devices such as this PROTO unit and the companion Aldec ACT-H3Ki-CQ256 reprogrammable adaptor before flight-device programming.
Typical applications include satellite payload data processing, spacecraft attitude control and telemetry interfaces, radiation-heavy orbital and deep-space missions, and high-reliability defense electronics. The 2M-gate density accommodates bus controllers, image preprocessing pipelines, and glueless interfaces to space-grade memories.
A key design consideration: PROTO units are intended for engineering validation, not space flight; order the corresponding flight suffix (V/B/E variants) for qualification hardware.

Tipik Uygulamalar
RTAX2000S-1CQ256PROTO için uygundur 6 uygulamas: Satellite Payload Data Processing, Spacecraft Attitude Control and Avionics, Deep-Space Mission Electronics, Defense and High-Reliability Ground Systems, FPGA Design Verification and Emulation, Telemetry, Tracking and Command (TT&C) Units.
Satellite Payload Data Processing
The RTAX2000S-1CQ256PROTO is used during the development of satellite payload processing boards, where its 2,000,000 equivalent gates and 21,504 CLBs provide enough capacity for image preprocessing, packet formatting, and high-rate data pipelines. The antifuse fabric is live at power-up, eliminating configuration-boot vulnerabilities on orbit. In the prototyping phase, engineers validate RTL, pin assignments, and I/O timing on the CQ256 footprint before programming flight antifuse devices, de-risking the transition to screened RTAX2000S/SL V-suffix parts and avoiding costly scrappage of one-time-programmable flight units.
Önerilen
Spacecraft Attitude Control and Avionics
Attitude determination and control electronics require deterministic, SEU-tolerant logic. The RTAX2000S fabric features SEU-hardened registers, reducing the triple-module redundancy overhead needed in SRAM FPGAs, with family SEU rates below 1E-10 errors per bit-day. The RTAX2000S-1CQ256PROTO lets control-loop designers validate star-tracker and gyro interfaces against real CQ256 I/O electrical behavior. Its 540 kbits of embedded SRAM with optional EDAC buffers sensor data, and segmentable clock resources support redundant timing domains common in fault-tolerant avionics architectures.
Önerilen
Deep-Space Mission Electronics
For missions beyond low Earth orbit, cumulative ionizing dose is severe; the RTAX2000S family is specified at 300 krad functional and 200 krad parametric total dose, per the Microchip RTAX-S/SL datasheet. During instrument development, the RTAX2000S-1CQ256PROTO allows teams to run radiation-test campaigns and design freeze validation on representative hardware. The nonvolatile antifuse technology stores configuration in the interconnect itself, immune to configuration-memory upsets - a structural advantage over SRAM FPGAs in deep-space environments where reconfiguration opportunities are limited.
Önerilen
Defense and High-Reliability Ground Systems
High-reliability defense electronics, missile guidance consoles, and ground stations reuse RTAX2000S designs where configuration integrity and power-up immediacy matter. The RTAX2000S-1CQ256PROTO supports laboratory validation on the same CQ256 footprint used in production boards. Because the fabric is library-compatible with commercial Axcelerator devices, teams can port proven commercial IP, but application note AC170 warns internal timing differs significantly - making PROTO-unit timing verification essential. The 250,000 additional ASIC gates accommodate custom hard-block equivalent functions in the design.
Önerilen
FPGA Design Verification and Emulation
Verification teams pair the RTAX2000S-1CQ256PROTO with the Aldec ACT-H3Ki-CQ256 adaptor, which mounts in the RTAX footprint and uses flash-based ProASIC3E technology for unlimited reprogramming. The workflow iterates RTL on the flash adaptor, then programs the PROTO antifuse device to validate one-time-programmable behavior, package parasitics, and final timing. This two-stage approach, documented in the Microchip-Aldec prototyping collaboration, dramatically reduces risk before committing flight parts, since each antifuse device supports exactly one programming cycle.
Önerilen
Telemetry, Tracking and Command (TT&C) Units
TT&C subsystems demand always-on logic that is functional the instant spacecraft power arrives; the RTAX2000S antifuse fabric is live at power-up with no external configuration device, a direct system-level benefit for command receivers that must respond during launch and early orbit. The RTAX2000S-1CQ256PROTO enables board bring-up of these units with representative silicon. With up to 684 user I/Os available at family level and the CQ256 footprint offering a balanced I/O count, the device interfaces decoders, UARTs, and CCSDS framing logic on a single chip.

Tasarım Notları
PROTO devices are engineering parts, not flight hardware. Program an antifuse RTAX device only after design freeze: antifuse technology is one-time programmable and a single mistake scraps the unit. Follow Microchip application note AC170 - although RTAX-S is library-compatible with Axcelerator, internal timing differs significantly, so never sign off timing using commercial Axcelerator models. Use RTAX-S timing models in Libero SoC and validate on the PROTO device before programming V-suffix flight parts.
If your spacecraft power budget is tight, evaluate the RTAX2000SL variant: the SL fabric provides the same 21,504-CLB density and CQ256 footprint with lower static power consumption, per the RTAX-S/SL family datasheet. Because S and SL are pin-compatible, you can prototype on either PROTO device and migrate to the SL flight part without PCB changes; update static-current analysis and thermal figures in your power budget when switching families.
Design the CQ256 land pattern once and reuse it across the RTAX2000S/SL PROTO and flight-suffix variants to preserve second-source flexibility within the family. Decouple all VCCA, VCCI, and VJTAG supplies with low-ESR ceramics placed close to the package; follow the RTAX-S/SL datasheet power-supply section for recommended capacitor values. Consider footprint compatibility with the Aldec ACT-H3Ki-CQ256 reprogrammable adaptor during layout so the flash-based prototyping path remains available.
