TMS320C6455BCTZA

Digital Signal Processor Dsp Overview

The TMS320C6455BCTZA is a fixed-point digital signal processor based on the C64x+ architecture, manufactured using a 0.09-μm CMOS process. It delivers up to 9600 MIPS at clock rates of 720 MHz, 850 MHz, 1 GHz, or 1.2 GHz. The device integrates a high-speed Serial RapidIO port, DDR2 memory controller, and Ethernet MAC. On-chip memory includes 32 KB L1P cache, 32 KB L1D cache, and 2 MB L2 unified RAM/cache. Key peripherals include EDMA3 with 64 channels, VCP2, TCP2, PCI, UTOPIA, and two McBSPs.

Digital Signal Processor Dsp Feature Summary

• C64x+ DSP core executing eight 32-bit instructions per cycle with 9600 MMACS performance
• Serial RapidIO interface supporting link rates from 1.25 Gbps to 3.125 Gbps
• Integrated DDR2 memory controller for 533-MHz SDRAM access
• 10/100/1000 Mb/s Ethernet MAC (EMAC) with MDIO support

Digital Signal Processor Dsp Applications

• Video and telecom infrastructure systems
• Wireless infrastructure applications
• Medical imaging and digital imaging processing

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (e.g., -720, -850, -1000, -1200) required for the target operating frequency. Confirm package availability as the CTZ, GTZ, and ZTZ variants share the same pinout but differ in physical construction. Ensure compliance with RoHS standards if applicable to the manufacturing revision.

Digital Signal Processor Dsp Selection Notes

Select the appropriate clock speed variant based on the required instruction cycle time (1.39 ns down to 0.83 ns). Consider the memory configuration needs, as L1 and L2 memories are configurable as cache or mapped RAM. Verify peripheral multiplexing requirements, as some pins are shared between HPI, PCI, and UTOPIA interfaces.

Digital Signal Processor Dsp Part Context

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

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the C6455 series include variants with different speed grades such as TMS320C6455CTZ7 or TMS320C6455GTZ7. Cross-family migration to other C64x+ devices requires verification of pin compatibility and memory map alignment.
