TMS320C6455DZTZA

Digital Signal Processor Dsp Overview

The TMS320C6455DZTZA is a fixed-point digital signal processor from Texas Instruments, utilizing the C64x+ DSP core. It operates at clock rates of 720 MHz, 850 MHz, 1 GHz, and 1.2 GHz, delivering up to 9600 MIPS/MMACS (16-bit). The device features a 64-bit external memory interface (EMIFA) and a 32-bit DDR2 memory controller supporting up to 512 MByte of addressable space. On-chip memory includes 32 KB L1P, 32 KB L1D, and 2 MB L2 unified RAM/cache. Key peripherals include Serial RapidIO, EMAC, PCI, EDMA3, and two McBSPs. It is housed in a 697-pin flip-chip plastic BGA package (CTZ/GTZ/ZTZ suffixes) with a 0.8-mm ball pitch.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (e.g., -7, -8) against the required operating frequency. Confirm the package type corresponds to the ZTZ suffix for the 697-pin flip-chip BGA. Ensure environmental specifications match the commercial or extended temperature requirements for the target application.

Digital Signal Processor Dsp Selection Notes

Select based on required processing throughput and available clock frequencies (up to 1.2 GHz). Consider the memory configuration needs for L1/L2 mapping versus caching. Verify peripheral availability, noting that some pins are multiplexed between HPI, PCI, and UTOPIA interfaces.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C6000 DSP platform, specifically the third-generation C64x+ family. It offers upward code compatibility with previous C6000 devices while providing enhanced performance through VelociTI VLIW architecture improvements and integrated high-speed interconnects like Serial RapidIO.
