TMS320C6746BZCEA3

Digital Signal Processor Dsp Overview

The TMS320C6746BZCEA3 is a fixed- and floating-point digital signal processor based on the C674x VLIW architecture. It operates at clock rates of 375 MHz or 456 MHz, delivering up to 3648 MIPS and 2746 MFLOPS. The device integrates 32 KB of L1 program cache, 32 KB of L1 data cache, and 256 KB of unified L2 RAM/cache. Core voltage ranges from 1.0 V to 1.3 V depending on frequency, with I/O support for 1.8 V or 3.3 V LVCMOS. It is housed in a 361-ball PBGA package (13 mm x 13 mm) with a 0.65-mm ball pitch.

Digital Signal Processor Dsp Feature Summary

• C674x DSP core supporting IEEE single and double precision floating point operations
• Integrated PRU subsystem with two independent 32-bit RISC cores
• EDMA3 controller providing 64 independent DMA channels
• Dual external memory interfaces: EMIFA and DDR2/mDDR controller

Digital Signal Processor Dsp Applications

• Currency inspection systems
• Biometric identification devices
• Low-end machine vision applications

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (e.g., A3 indicates 375 MHz) against design requirements. Confirm package dimensions match the 13 mm x 13 mm footprint. Check RoHS compliance status as manufacturing processes may vary by production date.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring mixed fixed/floating-point processing with low power consumption. Ensure the system supports the required core voltage scaling (1.2 V for 375 MHz). Verify peripheral availability, as some pins are multiplexed between UART, SPI, and McBSP functions.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C674x family, which is code-compatible with the C6000 DSP platform. It combines the performance of the C64x+ core with the floating-point capabilities of the C67x+ core. The ZCE package variant specifically denotes the 361-ball 0.65-mm pitch BGA form factor.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the same family include other speed grades of the TMS320C6746 or pin-compatible variants like the TMS320C6747 if additional peripherals are required.
