TMS320C6414TBGLZ8

Digital Signal Processor Dsp Overview

The TMS320C6414TBGLZ8 is a fixed-point digital signal processor from the C64x family, manufactured by Texas Instruments. It operates at a maximum clock frequency of 850 MHz with a cycle time of 1.17 ns. The device features an advanced VelociTI.2 VLIW architecture with eight independent functional units: six ALUs and two multipliers, delivering up to 6800 MIPS. It includes 16 KB L1P cache, 16 KB L1D cache, and 1 MB of unified L2 memory. Key peripherals include a 32-bit PCI interface, UTOPIA ATM controller, three McBSPs, and a 64-channel EDMA controller. It is housed in a 532-pin FCBGA package.

Digital Signal Processor Dsp Feature Summary

• VelociTI.2 Architecture: Eight highly independent functional units (six ALUs, two multipliers) supporting quad 8-bit and dual 16-bit operations.
• Memory Hierarchy: 16-KByte direct-mapped L1P cache, 16-KByte 2-way set-associative L1D cache, and 1-MByte flexible L2 mapped RAM/cache.
• Peripheral Integration: Includes 32-bit/33-MHz PCI master/slave interface, UTOPIA Level 2 slave ATM controller, and three multichannel buffered serial ports.
• External Memory Interfaces: Dual interfaces comprising a 64-bit EMIFA and a 16-bit EMIFB for synchronous and asynchronous memories.

Digital Signal Processor Dsp Applications

• Wireless infrastructure base stations
• ATM network controllers
• T1/E1 framing applications

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix '8' against the official datasheet to confirm the exact speed grade and temperature range, as TI part numbering conventions may vary. Ensure the source document explicitly lists the full part number TMS320C6414TBGLZ8 to avoid confusion with other C6414 variants like the -6 or -7 speed grades.

Digital Signal Processor Dsp Selection Notes

Select this component when a high-performance fixed-point DSP with integrated ATM capabilities is required. The C6414T lacks the VCP/TCP decoder coprocessors found in the C6416T but retains the PCI and UTOPIA interfaces. Verify that the 850 MHz performance meets system timing requirements and that the 532-pin BGA package fits the PCB layout constraints.

Digital Signal Processor Dsp Part Context

This device belongs to the TMS320C64x family, which offers software compatibility with the earlier C62x generation. The C6414T is pin-compatible with the C6415T and C6416T provided peripheral configurations are managed correctly, specifically disabling unused multiplexed pins like UTOPIA or PCI if not utilized.

Digital Signal Processor Dsp Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. For pin-compatible alternatives within the same family, refer to the TMS320C6415T or TMS320C6416T, noting differences in available peripherals such as the decoder coprocessors.
