TMS320C6748BZWTA3

Digital Signal Processor Dsp Overview

The TMS320C6748BZWTA3 is a fixed- and floating-point digital signal processor from Texas Instruments, featuring a C674x VLIW DSP core. It operates at clock frequencies of 375 MHz (1.2V) or 456 MHz (1.3V), delivering up to 3648 MIPS and 2746 MFLOPS. The device integrates 448KB of on-chip RAM, including 32KB L1P, 32KB L1D, and 256KB L2 memory, alongside an additional 128KB shared RAM. Key peripherals include a 10/100 Mbps Ethernet MAC, USB 2.0 OTG, SATA controller, and PRU subsystem. It is housed in a 361-ball NFBGA package with a 0.80mm ball pitch.

Digital Signal Processor Dsp Procurement Notes

Verify the ordering suffix 'BZ' corresponds to the specific package variant (NFBGA 361, 0.80mm pitch) and temperature grade required for the design. Confirm that the selected frequency bin (375MHz or 456MHz) aligns with the target power supply voltage constraints (1.2V vs 1.3V). Ensure compatibility with existing board layouts regarding the 361-ball footprint dimensions.

Digital Signal Processor Dsp Selection Notes

Select this component when high-performance floating-point processing is required alongside rich connectivity options like Ethernet and SATA. Consider the 456MHz version if maximum throughput is critical and the 1.3V core voltage is supported by the power design. Evaluate the PRU subsystem needs for deterministic real-time control tasks separate from the main DSP execution.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C674x series, which combines the performance of the C64x+ core with the floating-point capabilities of the C67x+ core. It is designed as a low-power applications processor within the TMS320C6000 platform, offering code compatibility with previous C6000 DSP families while adding advanced security features like Basic Secure Boot.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C6748ZCE is a pin-compatible alternative using a 0.65mm pitch package. Other members of the TMS320C6000 family may offer different peripheral sets or performance levels but require software adaptation due to varying instruction set superset relationships.
