Typical Applications
RTAX2000S-1CG1152V is suitable for 6 applications: Satellite Payload Data Processing, Spacecraft Command and Data Handling (C&DH), Telemetry, Tracking and Command (TT&C) Interfaces, Instrument Control and Signal Formatting, Launch Vehicle Avionics, Obsolescence Redesign / Legacy RTAX Migration.
Satellite Payload Data Processing
The RTAX2000S-1CG1152V fits payload processing chains where 2,000,000 equivalent gates implement compression engines, channelizers, or FEC blocks directly in flight silicon. Its 684 usable I/Os interface multiple ADC/DAC and high-speed data buses, while the antifuse fabric eliminates configuration-upset failures that SRAM FPGAs must scrub against. Typical designs clock logic from segmentable clock resources and buffer streams through embedded SRAM with built-in FIFO control. The trade-off is one-time programmability: validate the netlist on PROTO silicon or an Aldec adaptor before committing flight parts.
Recommended
Spacecraft Command and Data Handling (C&DH)
For C&DH modules, the RTAX2000S-1CG1152V implements telemetry encoders, decoders, and bus-interface glue logic in a single live-at-power-up chip. Because the antifuse configuration is permanent, the FPGA is operational the instant spacecraft power arrives - critical for launch and early-orbit operations with no configuration reload window. The 0.15 um CMOS process with 1.5 V core keeps static power low for power-constrained buses. The ceramic metal-sealed CGA1152 package withstands launch vibration and thermal cycling, and its 684 I/Os consolidate discrete board-level logic into one qualified device.
Recommended
Telemetry, Tracking and Command (TT&C) Interfaces
TT&C units benefit from the RTAX2000S-1CG1152V's deterministic, configuration-upset-immune fabric. receivers, command decoders, and formatter logic occupy a fraction of the 32,256 logic cells, leaving margin for obsolescence redesigns. The device's single-chip operation removes external PROM read paths from the command chain, reducing the SEE criticality analysis scope. With 684 inputs and 684 outputs available, multiple redundant receiver channels terminate on one die. Designs typically reserve embedded SRAM FIFOs for burst buffering between the RF baseband section and the spacecraft data bus.
Recommended
Instrument Control and Signal Formatting
Science instruments - imagers, spectrometers, particle detectors - use the RTAX2000S-1CG1152V as sequencer and formatter. The 2M-gate capacity holds timing generators, co-addition accumulators, and CCSDS packetization logic simultaneously. Low-power 1.5 V core operation matters in instrument enclosures with tight thermal budgets, and the antifuse fabric contributes no configuration SEU rate to instrument availability budgets. Segmentable clocks let engineers isolate noisy detector timing domains from telemetry domains on one die. Prototype timing-critical paths on RTAX2000S-1CG1152PROTO units before programming flight-ordered devices.
Recommended
Launch Vehicle Avionics
Launch avionics demands devices that are fully functional through shock, vibration, and short high-g missions - exactly the profile of the metal-sealed ceramic CGA1152 package. The RTAX2000S-1CG1152V implements flight-event sequencing, safe-and-arm interface logic, and redundancy voting. Live-at-power-up antifuse behavior guarantees logic is active without any boot sequence, a hard requirement in rapid-response flight phases. The 684 I/Os support triple-redundant channel implementations on one device, and the OTP fabric cannot be corrupted by the severe SEE environment encountered during ascent through radiation belts.
Recommended
Obsolescence Redesign / Legacy RTAX Migration
Programs with legacy RTAX2000S-based boards facing unit shortages use the same-footprint variants (RTAX2000SL-1CG1152V, RTAX2000S-LG1152V) as drop-in second sources within the Microchip family, since pinout and package are unchanged. Because RTAX-S is antifuse OTP, a redesigned netlist can be re-targeted to a fresh die without PCB modification. XAIPART's cross-reference data confirms these family variants share the identical 1152-terminal ceramic package, making board-level qualification impact minimal - typically limited to device re-screening and flight-lot recertification documentation.

Key Differentiators
- Standard RTAX-S fabric at 2M gates in CGA1152 (vs RTAX2000SL-1CG1152V)
- Flight screening (V suffix) (vs RTAX2000S-1CG1152PROTO)
- Right-sized density for most payload modules (vs RTAX4000S-1CG1272V)
Design Notes
RTAX-S devices are one-time-programmable: an antifuse blow is permanent. Never program flight-lot RTAX2000S-1CG1152V units with an unverified netlist. Use RTAX2000S-1CG1152PROTO parts or Aldec flash-based ProASIC3E adaptors (which fit the RTAX footprint directly) to iterate timing closure and functional verification. Only after sign-off on the prototype should the identical programming file be committed to flight silicon.
Estimated: the RTAX2000S fabric operates from a 1.5 V core per the RTAX-S family datasheet. At 2M gates, dynamic power depends heavily on toggle rate - run Microchip's power estimator (Libero flow) with your actual utilization and clock frequency before sizing the spacecraft power budget. Ceramic CGA packages dissipate heat poorly compared to thermal-pad packages, so place high-switching logic away from die center and verify junction temperature against the derated space ambient.
The 1152-terminal ceramic column (CCGA) package has stiff, brittle columns: control PCB local CTE mismatch and use under-stiffening or wedge-lock mounting where launch profiles demand. Follow the Microchip RTAX-S application notes for column-grid fanout; escape routing on 1.0 mm+ column pitch typically requires via-in-pad or dog-bone fanout. Verify package land pattern against the latest datasheet revision before release - column tolerances are tighter than plastic BGA.
Compliance Information
Space-grade ceramic package; standard commercial environmental compliance declarations are typically not the screening criterion for this product. Verify per Microchip product page.
