It delivers 160 MIPS at 160 MHz with 6.25-ns instruction cycle time, features dual-access 128K × 16-bit on-chip RAM, 16K × 16-bit ROM, and integrated peripherals including three McBSPs, six-channel DMA, and an on-chip PLL clock generator.

For engineers reviewing the SM320VC5416PGE16EP datasheet, SM320VC5416PGE16EP pinout, SM320VC5416PGE16EP application, or SM320VC5416PGE16EP equivalent, key selection criteria include radiation-hardened operation, 144-pin LQFP (PGE) package compatibility, 3.3-V I/O / 1.6-V core voltage support, extended addressing for up to 8M × 16-bit external program space, and deterministic real-time execution in harsh environments.

Technical Context

The SM320VC5416PGE16EP implements a modified Harvard architecture with three independent 16-bit data memory buses and one program memory bus, enabling simultaneous access to program and data memory. Its 40-bit ALU includes a barrel shifter and dual accumulators, supporting single-cycle MAC operations via a 17 × 17-bit multiplier and dedicated adder.

On-chip peripherals include a software-programmable wait-state generator, programmable bank-switching logic, six-channel DMA controller with autoinitialization and doubleword transfer modes, and three multichannel buffered serial ports (McBSPs) configurable as SPI master/slave or general-purpose I/O. The device supports HPI8/16 host-port interface and IEEE 1149.1 JTAG boundary scan for emulation and test.

FAQ

What is the maximum operating frequency of the SM320VC5416PGE16EP?

The SM320VC5416PGE16EP operates at a maximum frequency of 160 MHz, delivering 160 million instructions per second (MIPS) with a 6.25-ns single-cycle instruction execution time. This speed is achieved using its on-chip PLL clock generator, which multiplies an external input clock (e.g., 10 MHz crystal) by a factor of 16. The SM320VC5416PGE16EP maintains this performance across its full military temperature range (–55°C to 125°C) and under radiation exposure conditions.

Does the SM320VC5416PGE16EP support JTAG debugging?

Yes, the SM320VC5416PGE16EP integrates IEEE Std 1149.1 (JTAG) boundary scan logic and on-chip scan-based emulation logic. This allows full visibility into internal registers and signal paths during development and field diagnostics. Engineers can perform real-time debugging, memory inspection, and firmware loading through standard JTAG adapters without requiring additional debug pins - a critical capability for validating SM320VC5416PGE16EP-based systems in safety-critical applications.

What memory configuration does the SM320VC5416PGE16EP provide on-chip?

The SM320VC5416PGE16EP includes 128K × 16-bit on-chip RAM divided into eight 8K × 16-bit dual-access blocks and eight 8K × 16-bit single-access blocks, plus 16K × 16-bit on-chip ROM. The dual-access RAM enables simultaneous program and data access within a single cycle - essential for zero-wait-state execution of tight control loops. The ROM stores boot code and fixed routines, and both memory types are radiation-hardened to maintain integrity in high-radiation environments.

How many serial interfaces does the SM320VC5416PGE16EP include, and what protocols do they support?

The SM320VC5416PGE16EP integrates three multichannel buffered serial ports (McBSPs). Each McBSP supports TDM, I2S, and SPI protocols in both master and slave configurations, with independent sample-rate generators and programmable clock polarity/phase. They also operate as general-purpose I/O ports. These interfaces allow the SM320VC5416PGE16EP to connect directly to ADCs, DACs, codecs, and FPGAs - enabling flexible data acquisition and communication in radar, telemetry, and instrumentation systems.

Is the SM320VC5416PGE16EP pin-compatible with commercial C54x devices?

Yes, the SM320VC5416PGE16EP shares identical pinout and electrical characteristics with the commercial TMS320C5416PGE16 in the 144-pin LQFP (PGE) package. However, the SM320VC5416PGE16EP adds radiation tolerance, extended temperature qualification (–55°C to 125°C), and MIL-PRF-38535 Class V compliance. Hardware designs targeting the commercial part can be reused, but firmware must account for differences in reset behavior and power-up sequencing under radiation stress.
