TMX320C28343ZHH

Digital Signal Processor Dsp Overview

The TMX320C28343ZHH is an engineering sample of the TMS320C2834x Delfino microcontroller family from Texas Instruments. It features a C28x 32-bit CPU core operating at up to 150 MHz, integrated with a Control Law Accelerator (CLA) for parallel processing. The device includes 512 KB of onboard Flash memory and 160 KB of SRAM. Key peripherals consist of two 12-bit ADCs with up to 28 channels, enhanced High-Resolution PWM modules, and multiple communication interfaces including CAN, SCI, SPI, and I2C. This specific part number denotes a pre-production unit intended for evaluation purposes.

Digital Signal Processor Dsp Part Context

The 'TMX' prefix indicates that this component is an engineering sample or pre-production silicon, distinct from mass-produced commercial parts which typically use the 'TMS' prefix. These samples are provided by Texas Instruments for design verification and software development prior to final product qualification. The ZHH suffix specifies the package type and temperature rating, corresponding to a 176-pin ZQFP package suitable for high-density mounting.

Digital Signal Processor Dsp Replacement Considerations

For production designs, substitute the TMX320C28343ZHH with the qualified commercial equivalent TMS320C28343ZHH. Verify that the final part meets all automotive or industrial reliability standards required for the end application, as engineering samples may not have undergone full qualification testing.
