TMS320C6455BZTZ8

Digital Signal Processor Dsp Overview

The TMS320C6455BZTZ8 is a fixed-point digital signal processor based on the C64x+ architecture. It features an 8-issue VLIW core capable of executing eight 32-bit instructions per cycle, delivering up to 9600 MIPS at clock rates of 720 MHz, 850 MHz, 1 GHz, or 1.2 GHz. The device integrates 32 KB L1P and 32 KB L1D memory, plus 2 MB of unified L2 RAM/cache. Key peripherals include four Serial RapidIO links (v1.2 compliant), a 10/100/1000 Mb/s Ethernet MAC, a 64-bit EMIFA, and a DDR2 memory controller. It utilizes a 697-pin BGA package with a 0.8 mm ball pitch.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (e.g., -720, -850, -1000, -1200) required for the target clock frequency. Confirm that the ZTZ package variant matches the board layout requirements for the 697-pin flip-chip plastic BGA. Ensure voltage supply rails align with the specified 1.2V/1.25V core and 1.2V-3.3V I/O options.

Digital Signal Processor Dsp Selection Notes

Select the appropriate speed bin based on the required instruction cycle time (1.39 ns to 0.83 ns). Consider the memory configuration needs, as L1 and L2 can be mapped as RAM or cache. Verify peripheral pin multiplexing constraints, as some interfaces like PCI and HPI share pins. Check compatibility with existing development tools such as the C compiler and debugger interface.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C6000 DSP platform, specifically the third-generation C64x+ family. It succeeds earlier C64x devices with upward code compatibility. The ZTZ suffix denotes the 697-pin flip-chip plastic BGA package. Other variants in this family include CTZ and GTZ packages, and different speed grades denoted by numeric suffixes.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same package and pinout are limited to other speed grades of the TMS320C6455 (e.g., TMS320C6455CTZ8, TMS320C6455GTZ8). Cross-family migration to other C6000 devices requires careful review of pin compatibility and memory map differences.
