TMS320C6414TBCLZA8

Digital Signal Processor Dsp Overview

The TMS320C6414TBCLZA8 is a fixed-point digital signal processor from the C64x family, manufactured by Texas Instruments. It features an advanced VelociTI.2 VLIW architecture with eight independent functional units: six ALUs and two multipliers. The device supports clock rates up to 1 GHz (1-ns instruction cycle) and delivers up to 8000 MIPS. It includes 16 KB L1P cache, 16 KB L1D cache, and 1 MB of configurable L2 memory. Key peripherals include a 32-bit PCI interface, UTOPIA ATM controller, three McBSPs, and an EDMA controller. It operates on a 3.3-V I/O supply with a 1.2-V core voltage at maximum speed.

• T1/E1 telecommunications framing

Digital Signal Processor Dsp Procurement Notes

Verify the ordering suffix 'CLZA8' corresponds to the specific package variant (532-pin BGA) and temperature range required for the design. Confirm that the silicon revision matches the target application requirements, as electrical characteristics may vary between revisions. Ensure compatibility with existing board layouts due to the specific pinout of the CLZ package.

Digital Signal Processor Dsp Selection Notes

Select this model when high-performance fixed-point processing is required alongside specific peripheral interfaces like PCI and UTOPIA. It is pin-compatible with the C6415T and C6416T if those devices' unique peripherals are disabled. Consider the power consumption implications of the 1.2-V core voltage at 1 GHz operation compared to lower-speed variants.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C64x family, which is fully software-compatible with the earlier C62x series. The C6414T variant specifically lacks the VCP/TCP decoder coprocessors found in the C6416T but retains the PCI and UTOPIA peripherals present in the C6415T/C6416T. It represents a high-end option within the commercial temperature range of the C64x generation.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C6415TBCLZA8 and TMS320C6416TBCLZA8 are pin-compatible alternatives. Substitution requires disabling the PCI or UTOPIA peripherals on the replacement part to match the C6414T's peripheral configuration. Other C64x family members may require significant hardware redesign due to pin or feature differences.
