SMJ320C25GBM

The Texas Instruments SMJ320C25GBM is a military-grade 16-bit fixed-point digital signal processor from the SMJ320C25 family, manufactured for high-reliability defense and aerospace environments. Based on TI’s TMS320C2x architecture, the device integrates a single-cycle multiply-accumulate unit, on-chip program and data RAM, and multiple serial ports, providing deterministic real-time processing in a hermetic 68-pin ceramic pin grid array (CPGA) package. It is processed to the full military temperature range and relevant MIL-PRF-38535 flows, ensuring stable operation under extreme thermal and mechanical stress.

Typical applications include digital filtering, FFT-based spectrum analysis, and control loops within radar, sonar, electronic warfare, and precision-guided munitions, where fixed-point arithmetic and low-latency interrupt handling support mission-critical signal chains. In avionics and flight control computers, the SMJ320C25 often serves as a co-processor for sensor fusion and actuator management. Procurement engineers should note that this device resides in a mature product lifecycle. While designed for long-term military program support, availability may be subject to allocation, and sourcing requires verified chain-of-custody and counterfeit mitigation measures appropriate for a hermetic, full-mil qualified component.
