SM320C6701ZMBW14

Digital Signal Processor Dsp Overview

The SM320C6701ZMBW14 is a military-grade floating-point digital signal processor from the TMS320C6000 series, manufactured by Texas Instruments. It utilizes the VelociTI VLIW architecture with an 8-issue C67x core. The device supports IEEE single and double-precision instructions, delivering up to 1 GFLOPS performance at clock rates of 120, 150, or 167 MHz. Key specifications include 512 Kbit internal program/cache memory and 512 Kbit dual-access data RAM. It features eight independent functional units: four floating-point/integer ALUs, two integer ALUs, and two multipliers. The component operates within extended temperature ranges (SMJ: -55°C to 115°C; SM: -40°C to 90°C) and is housed in a 144-pin PBGA package.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (e.g., ZMB) against the required clock frequency. Confirm the thermal profile matches the intended operating environment, as the SM variant differs from the SMJ variant in temperature range. Ensure ESD handling protocols are followed due to humidity sensitivity classification. Cross-reference the datasheet revision date to confirm peripheral register compatibility.

Digital Signal Processor Dsp Selection Notes

Select this component when high-throughput floating-point arithmetic is required in harsh environments. Compare the 167 MHz maximum speed against lower-speed variants if power consumption is a constraint. Verify that the 512 Kbit on-chip memory suffices for algorithm buffers; otherwise, plan for external SDRAM/SBSRAM connection via the EMIF interface. Check pin compatibility with existing C6201 designs if migrating from fixed-point architectures.

Digital Signal Processor Dsp Part Context

This part belongs to the SMJ320C67x family, which adapts the commercial TMS320C6701 DSP for defense applications. It shares architectural similarities with the TMS320C6711 but offers higher clock speeds and military radiation hardening standards. Unlike the C6711, it lacks integrated audio codecs, requiring external interfaces for analog signal conversion.

Digital Signal Processor Dsp Replacement Considerations

Publicly confirmed direct substitutes include other SMJ320C6701 speed grades (e.g., SMJ320C6701ZMW14). For non-military applications, the TMS320C6701 series serves as a functional equivalent, though environmental ratings differ.
