TMS320VC5470ZHKA

Digital Signal Processor Dsp Overview

The TMS320VC5470ZHKA is a fixed-point digital signal processor integrating a TMS320C54x DSP core and an ARM7TDMI RISC microcontroller unit. It operates at a maximum clock frequency of 100 MHz with a 16-bit data format. The device features on-chip RAM, including DSP memory and MCU SRAM, alongside interfaces for external SDRAM. Key peripherals include a multichannel buffered serial port (McBSP), DMA controller, UART, SPI, I²C, and GPIO. It utilizes a 257-ball MicroStar BGA package and requires a 3.3V supply.

Digital Signal Processor Dsp Feature Summary

• Dual-core architecture combining TMS320C54x DSP and ARM7TDMI MCU
• Maximum operating frequency of 100 MHz
• Integrated McBSP, DMA, UART, SPI, and I²C interfaces
• Supports external SDRAM via dedicated MCU interface

Digital Signal Processor Dsp Applications

• Embedded systems requiring combined DSP and control processing

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix ZHKA against the official datasheet to confirm temperature range and package details. Ensure compatibility with 3.3V power supplies and check for lead-free compliance if required by local regulations. Confirm availability through authorized distributors as production status may vary.

Digital Signal Processor Dsp Selection Notes

Select this component when both high-performance fixed-point DSP operations and general-purpose RISC control are needed in a single chip. Consider the 100 MHz speed limit and available on-chip memory sizes. Evaluate peripheral needs such as McBSP channels and SDRAM interface requirements before choosing over separate DSP and MCU solutions.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320VC5470 family, which represents one of the first commercially available DSP/RISC combination processors from Texas Instruments. It is designed to simplify system design by integrating two distinct processor cores on a single die, reducing board space and interconnect complexity compared to discrete solutions.
