TMS320C6455BGTZ

Digital Signal Processor Dsp Overview

The TMS320C6455BGTZ is a fixed-point digital signal processor from Texas Instruments, part of the C6000 platform. It features a C64x+ DSP core operating at clock rates up to 1.2 GHz, delivering 9600 MIPS/MMACS (16-bit). The device utilizes a 0.09-μm CMOS process and includes a two-level memory architecture with 32KB L1P, 32KB L1D, and 2MB L2 unified RAM/cache. Key peripherals include an EMAC, Serial RapidIO, DDR2 controller, PCI, and EDMA3.

Digital Signal Processor Dsp Feature Summary

• C64x+ DSP Core: 8 functional units executing eight 16-bit MACs per cycle; supports 720 MHz, 850 MHz, 1 GHz, and 1.2 GHz frequencies.
• Memory Architecture: 32KB L1 Program Cache, 32KB L1 Data Cache, and 2MB L2 Unified Mapped RAM/Cache.
• High-Speed Interfaces: Four 1x Serial RapidIO links (v1.2), 10/100/1000 Mb/s Ethernet MAC (EMAC), and 32-bit DDR2 Memory Controller.
• Peripherals: Includes PCI (33/66 MHz), UTOPIA ATM Slave, two McBSPs, I2C, GPIO, and Enhanced Direct Memory Access (EDMA3) with 64 channels.

Digital Signal Processor Dsp Applications

• Video and telecom infrastructure processing
• Wireless infrastructure baseband processing
• Imaging and medical equipment signal processing

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 package availability as the GTZ suffix denotes a standard plastic BGA, while CTZ/ZTZ denote flip-chip variants. Ensure RoHS compliance status matches project requirements.

Digital Signal Processor Dsp Selection Notes

Select based on required CPU frequency (720 MHz to 1.2 GHz) and temperature range (Commercial or Extended). Verify peripheral pin multiplexing constraints, as some pins are shared between HPI, PCI, and UTOPIA interfaces. Check power supply requirements for 1.2V/1.25V core and 1.2V–3.3V I/O levels.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C6455 series within the C6000 DSP family. It shares the same silicon and architectural features as other suffixes (CTZ, ZTZ) but differs in packaging type. The GTZ variant specifically refers to the 697-pin Plastic Ball Grid Array package.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements include other TMS320C6455 variants such as TMS320C6455CTZ or TMS320C6455ZTZ, provided the package form factor is adapted. Upgrades within the C6000 family like the TMS320C6457 offer similar cores with different peripheral sets.
