Product details
Overview
SM320VC5416HFGW10 from Texas Instruments is a radiation-hardened, fixed-point digital signal processor (DSP) designed for high-reliability military and aerospace applications. It delivers 100 MIPS at 100 MHz with 128K × 16-bit on-chip RAM, 16K × 16-bit ROM, a 40-bit ALU, 17×17-bit MAC unit, and six-channel DMA - enabling real-time radar signal processing, secure communications modulation, and onboard telemetry filtering.
For engineers reviewing the SM320VC5416HFGW10 datasheet, SM320VC5416HFGW10 pinout, SM320VC5416HFGW10 application, or SM320VC5416HFGW10 equivalent, key selection criteria include MIL-PRF-38535 QML qualification, 164-pin CQFP (HFG) package compatibility, 3.3-V I/O / 1.5-V core voltage operation, 10-ns instruction cycle timing, and support for HPI8/16, McBSPs, and PLL-based clock generation.
Technical Context
The SM320VC5416HFGW10 implements an advanced multibus architecture with three independent 16-bit data memory buses and one program memory bus, enabling simultaneous access to program, data, and I/O spaces. Its 40-bit ALU includes a barrel shifter and dual accumulators, while the dedicated 17×17-bit multiplier + adder supports non-pipelined single-cycle MAC operations critical for FIR/IIR filtering.
On-chip peripherals include a software-programmable wait-state generator, programmable bank-switching logic, a 16-bit hardware timer, and three multichannel buffered serial ports (McBSPs) supporting TDM, I2S, and SPI protocols. The integrated PLL clock generator accepts external crystal or clock input and supports multiply-by-N, divide-by-2, and divide-by-4 modes.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-point DSP applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMJ320C6701HFGW10 | Floating-point C67x core, 167-MIPS peak, 32K × 32-bit L1 RAM, no HPI, different instruction set - not software-compatible. | Used where floating-point precision required for adaptive beamforming or wideband channel estimation. | Select only when algorithmic precision demands exceed fixed-point dynamic range; requires full firmware rewrite and PCB layout review. |
| SM320VC5509APGEA | Lower-power 55x-generation DSP, 200-MIPS, 64K × 16-bit RAM, 32K × 16-bit ROM, 144-pin LQFP - commercial temperature grade, no MIL-PRF-38535 qualification. | Deployed in ground-based test equipment and non-flight avionics where cost and power efficiency outweigh radiation tolerance. | Consider for development prototyping or non-mission-critical subsystems; not acceptable for flight hardware without redesign and recertification. |
Compared with SMJ320C6701HFGW10 and SM320VC5509APGEA, the SM320VC5416HFGW10 uniquely balances radiation-hardened reliability, deterministic fixed-point performance, and mature toolchain support - making it the preferred choice for legacy and new-production MIL-SPEC radar and comms platforms requiring long-term obsolescence management.

FAQ
What is the maximum operating frequency of the SM320VC5416HFGW10?
The SM320VC5416HFGW10 operates at a maximum CPU clock frequency of 100 MHz, achieving 100 million instructions per second (MIPS) with a 10-ns single-cycle instruction execution time. This frequency is enabled by its on-chip PLL clock generator when configured with appropriate external crystal or clock source and supported by stable 1.5-V core and 3.3-V I/O supplies.
Does the SM320VC5416HFGW10 support JTAG debugging?
Yes, the SM320VC5416HFGW10 integrates IEEE Std 1149.1 (JTAG) boundary scan logic and on-chip scan-based emulation logic. This enables full visibility into internal registers and memory during development, supporting real-time debugging, flash programming, and structural testing without requiring additional probe hardware - a critical capability for verifying functionality in radiation-hardened designs.
What memory configuration options does the SM320VC5416HFGW10 provide at boot?
The SM320VC5416HFGW10 uses the MP/MC pin to select boot mode: when MP = 1, the device boots from on-chip 16K × 16-bit ROM containing a bootloader; when MP = 0, it boots from external memory. The internal memory map is further configurable via the PMST register, allowing flexible allocation of the 128K × 16-bit RAM between program and data spaces during runtime.
How many serial interfaces does the SM320VC5416HFGW10 include, and what protocols do they support?
The SM320VC5416HFGW10 includes three multichannel buffered serial ports (McBSP0–McBSP2), each supporting TDM, I2S, and SPI master/slave modes. Each McBSP provides independent transmit/receive clocks and frame syncs, programmable word length (8–32 bits), and automatic clock polarity/frame sync edge control - enabling simultaneous voice, data, and control channel handling in secure radio systems.
Is the SM320VC5416HFGW10 pin-compatible with other members of the VC54xx family?
No, the SM320VC5416HFGW10 is not pin-compatible with earlier VC54xx devices such as the VC5402 or VC5409 due to differences in pin count (164-pin HFG vs. 144-pin or 120-pin packages), signal assignment, and peripheral integration. While software may share architectural similarities, hardware redesign is required to migrate to or from the SM320VC5416HFGW10.
