Application Scenarios & Design Considerations

Floating-Point Digital Signal Processors, Military

Alternative Part Number

  • TMS320C40GFM50 --: Same C40 DSP core in the same ceramic CPGA package and 50 MHz speed grade, differing only in the commercial TMS prefix versus the SMJ military prefix, making it the closest functional drop-in.
  • TMS320C44GFM50 --: Pin-compatible member of the same C4x floating-point DSP family with the same package and 50 MHz rating, offering similar performance with added communication ports.
  • ADSP-21060KSZ-160 --: Alternative high-performance floating-point DSP from the SHARC family that can serve as a functional substitute in signal-processing designs when the C40 is unavailable.
