TMS320C6415TBZLZ1

Digital Signal Processor Dsp Overview

The TMS320C6415TBZLZ1 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. Key specifications include 16 KB L1P cache, 16 KB L1D cache, and 1 MB of configurable L2 memory. It integrates a 32-bit PCI interface, UTOPIA ATM controller, three McBSPs, and a 64-channel EDMA controller. The component is housed in a 532-pin BGA package.

Digital Signal Processor Dsp Applications

• Wireless infrastructure base stations
• ATM network processing
• Digital media processing

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'ZLZ' corresponds to the required commercial temperature range and lead-free status if applicable, as the datasheet notes GLZ, ZLZ, and CLZ are distinct package variants. Confirm that the 'T' designation indicates the extended temperature capability or specific speed grade intended for the application environment. Cross-reference the revision history (SPRS226M) to ensure the latest electrical characteristics are applied.

Digital Signal Processor Dsp Selection Notes

Select this model when pin compatibility with C6414T/C6416T is required but the specific peripheral mix of C6415T (PCI and UTOPIA present, no VCP/TCP) is needed. Ensure the design accounts for the multiplexed pins between UTOPIA/McBSP1 and PCI/HPI/GPIO. Verify power supply requirements: 1.1 V core for 600 MHz operation and 1.2 V core for speeds above 600 MHz.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C64x DSP family, which is software-compatible with the earlier C62x series. The C6415T variant specifically bridges the feature set of the C6414T and C6416T by including PCI and UTOPIA peripherals while omitting the dedicated VCP and TCP decoder coprocessors found in the C6416T.

Digital Signal Processor Dsp Replacement Considerations

Public confirmed substitute part numbers: TMS320C6414TBZLZ1, TMS320C6416TBZLZ1. These devices are pin-compatible provided peripheral configurations match the constraints outlined in the datasheet.
