TMS320C6455BCTZ

Digital Signal Processor Dsp Overview

The TMS320C6455BCTZ is a fixed-point digital signal processor based on the C64x+ architecture, operating at clock rates of 720 MHz, 850 MHz, 1 GHz, or 1.2 GHz. It delivers up to 9600 MIPS using eight functional units capable of executing four 16-bit multiply-accumulate operations per cycle. The device features a 697-pin flip-chip plastic BGA (CTZ) package with a 0.8-mm ball pitch. On-chip memory includes 32 KB L1P cache, 32 KB L1D cache, and 2 MB of unified L2 RAM/cache. Integrated peripherals include a Serial RapidIO port, DDR2 memory controller, Ethernet MAC, PCI interface, and EDMA3 controller.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (e.g., -720, -850, -1000, -1200) required for the target system clock frequency. Confirm that the CTZ package variant matches the PCB footprint design. Ensure compliance with RoHS standards as indicated in production documentation.

Digital Signal Processor Dsp Selection Notes

Select the appropriate speed grade based on the required instruction cycle time: 1.39 ns for 720 MHz, 1.17 ns for 850 MHz, 1 ns for 1 GHz, or 0.83 ns for 1.2 GHz. Consider the power supply requirements, which vary between 1.2 V and 1.25 V depending on the selected frequency.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C6000™ DSP platform, specifically the third-generation C64x+ family. It is upward code-compatible with previous C6000 devices, allowing migration from earlier architectures while leveraging enhanced VelociTI™ VLIW capabilities.

Digital Signal Processor Dsp Replacement Considerations

Compatible substitutes within the same family include TMS320C6455CTZ, TMS320C6455GTZ, and TMS320C6455ZTZ. These variants share identical functionality but differ in package type (flip-chip vs. standard BGA). Verify pin compatibility and thermal characteristics when substituting.
