Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix GNZ indicates big-endian support and a 27 x 27 mm package. Confirm availability status as production data may vary by region. Ensure power supply requirements match the 1.4-V core and 3.3-V I/O specifications for the -600 speed grade.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high-throughput video processing with integrated networking capabilities. The GNZ suffix provides big-endian mode compatibility. Compare against DM641 or DM643 variants if different pin counts or peripheral sets are required. Ensure PCB layout supports the 548-pin BGA thermal and electrical constraints.

Digital Signal Processor Dsp Part Context

The TMS320DM642 belongs to the TMS320C6000 DSP platform, specifically designed for digital media applications. It is code-compatible with other C64x devices but includes specialized peripherals like the EMAC and video ports not found in standard C64x processors. The GNZ variant is part of the second-generation DM64x family utilizing the 0.13-µm process technology.

Digital Signal Processor Dsp FAQ

What is the difference between the GNZ and GDK suffixes?

The GNZ suffix indicates a 27 x 27 mm 548-pin BGA package with a 1.0-mm ball pitch and supports both little-endian and big-endian modes. The GDK suffix denotes a 23 x 23 mm 548-pin BGA package with a 0.8-mm ball pitch and supports only little-endian mode.

Does the TMS320DM642GNZ600 support floating-point operations?

No, the TMS320DM642 is a fixed-point digital signal processor. It utilizes the C64x architecture optimized for fixed-point arithmetic and VelociTI.2 extensions for integer-based video and imaging algorithms.

What is the internal core voltage for the -600 speed grade?

The TMS320DM642GNZ600 requires a 1.4-V internal core voltage. The I/O voltage is 3.3 V.
