TMS320C6455BZTZ7

Digital Signal Processor Dsp Overview

The TMS320C6455BZTZ7 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 and 9600 MMACS (16-bit). The device features a 64-bit external memory interface (EMIFA) and a DDR2 memory controller supporting DDR2-533 SDRAM with a 512 M-byte addressable space. On-chip memory includes 32 KB L1P cache, 32 KB L1D cache, and 2 MB L2 unified RAM/cache. Key peripherals include four Serial RapidIO links, a 10/100/1000 Mb/s Ethernet MAC, PCI, UTOPIA, two McBSPs, and an EDMA3 controller with 64 channels.

• Wireless infrastructure applications
• Medical imaging devices

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (e.g., -720, -850, -1000, -1200) required for the target frequency, as the base model number does not specify it. Confirm RoHS compliance status and package availability through official Texas Instruments channels or authorized distributors. Ensure the ordering suffix matches the desired temperature range and packaging format.

Digital Signal Processor Dsp Selection Notes

Select the appropriate speed grade based on the required instruction cycle time: 1.39 ns (720 MHz), 1.17 ns (850 MHz), 1 ns (1 GHz), or 0.83 ns (1.2 GHz). The ZTZ suffix indicates a 697-pin flip-chip plastic BGA package with a 0.8 mm ball pitch. Consider power supply requirements, including 1.25 V/1.2 V core voltage and 1.25 V–3.3 V I/O voltages, when designing the power delivery network.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C6000 DSP platform, specifically the C64x+ generation. It utilizes a 0.09-μm CMOS process technology. The device is upward code-compatible with previous C6000 series processors, allowing migration from older architectures while leveraging enhanced VelociTI™ VLIW capabilities and new instruction set extensions.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacements within the same package are limited to other speed grades of the TMS320C6455 family (e.g., TMS320C6455CTZ7, TMS320C6455GTZ7). For different performance levels, consider the broader C64x+ family, but verify peripheral compatibility and memory map differences.
