TMS320C6455DZTZA8

Digital Signal Processor Dsp Overview

The TMS320C6455DZTZA8 is a fixed-point digital signal processor from the Texas Instruments DaVinci family, built on the C64x+ DSP core. It operates at a maximum clock frequency of 66.6 MHz and utilizes a 32-bit data bus width. The device features an internal L1 cache with 32 kB instruction and 32 kB data memory. It is housed in a 697-pin FCBGA package (24 x 24 mm, 0.80 mm pitch) and supports surface-mount installation. The processor functions within a temperature range of 0°C to +90°C and requires a 1.2 V core supply voltage.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix 'A8' against the manufacturer's official datasheet to confirm pinout compatibility and revision status. Ensure that the procurement channel provides RoHS compliance documentation as indicated in component listings. Confirm moisture sensitivity level handling requirements prior to assembly.

Digital Signal Processor Dsp Selection Notes

Select this component when a C64x+ architecture is required for fixed-point algorithms. Verify that the 66.6 MHz operating speed meets system timing constraints. Check interface availability for Ethernet and USB if multimedia connectivity is necessary. Ensure the PCB layout supports the 697-pin BGA footprint and thermal dissipation needs.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320DM648/TMS320C6455 series within the DaVinci platform. It shares architectural similarities with other C64x+ devices but is distinct in its specific peripheral integration and package configuration. It serves as a bridge between general-purpose DSPs and application-specific processors in embedded vision tasks.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes include other TMS320C6455 variants with compatible pinouts. Cross-referencing with the TMS320DM648 series may be necessary for higher performance requirements, though pin compatibility must be verified.
