TMS320C6742BZWT2

Digital Signal Processor Dsp Overview

The TMS320C6742BZWT2 is a fixed- and floating-point digital signal processor based on the C674x VLIW architecture, operating at a maximum frequency of 200 MHz. It delivers up to 1600 MIPS and 1200 MFLOPS performance. The device integrates a two-level cache memory system comprising 32 KB L1P program RAM/cache, 32 KB L1D data RAM/cache, and 64 KB unified L2 mapped RAM/cache. Key peripherals include an Enhanced Direct Memory Access Controller 3 (EDMA3) with 64 independent channels, dual external memory interfaces (EMIFA and DDR2/mDDR), and various communication modules such as McASP, McBSP, SPI, I2C, and UART.

Digital Signal Processor Dsp Procurement Notes

Verify the specific package variant against the datasheet; the ZCE package is 13 mm x 13 mm PBGA with 0.65-mm pitch, while the ZWT package is 16 mm x 16 mm PBGA with 0.80-mm pitch. Confirm that the ordering suffix corresponds to the required temperature range and packaging configuration. Ensure compatibility with development tools such as TI DSP BIOS and the Chip Support Library for software integration.

Digital Signal Processor Dsp Selection Notes

Select this component when high-performance fixed- and floating-point processing is required within a low-power envelope. The C674x core is code-compatible with the C6000 platform, facilitating migration from legacy designs. Consider the flexible L2 memory partitioning for applications requiring specific cache-to-RAM ratios. Verify peripheral availability, as some pins are multiplexed and cannot be used simultaneously.

Digital Signal Processor Dsp Part Context

The TMS320C6742 belongs to the C6000 DSP platform, combining the performance of the C64x+ core with the floating-point capabilities of the C67x+ core. It serves as a low-power applications processor designed to enable rapid market entry for devices with robust operating systems and rich user interfaces. The device supports both commercial and extended temperature ranges.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C6742DPTPA3 is a compatible alternative in the same family, offering similar C674x core features but housed in a 176-pin HLQFP package instead of the 361-ball PBGA. Both devices share code compatibility with the C6000 platform.
