Digital Signal Processor Dsp Procurement Notes

Verify the specific silicon revision and speed grade suffixes against the manufacturer's current orderable information. Confirm that the 176-pin HLQFP PowerPAD package dimensions match the target PCB footprint requirements. Ensure design compliance with the specified 3.3-V LVCMOS I/O voltage levels for all external connections.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring high-performance floating-point processing with low power consumption. The C6745 variant provides 16-bit SDRAM support via EMIFB, whereas the C6747 offers additional shared memory and higher-speed USB capabilities. Evaluate the peripheral multiplexing constraints to ensure required interfaces are available simultaneously.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C674x family, which includes the C6745 and C6747 devices. Both share the same DSP core and instruction set compatibility with the C6000 platform. The primary distinction lies in the package type and specific peripheral availability, such as the additional 128KB shared RAM and LCD controller found only in the C6747.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C6747 is a pin-compatible alternative within the same family but utilizes a 256-ball BGA package and includes additional peripherals like an LCD controller and HPI interface. Verify mechanical fit and peripheral requirements before substitution.
