TMS320DM6433ZDUL

Digital Signal Processor Dsp Overview

The TMS320DM6433ZDUL is a digital media processor from Texas Instruments, part of the DaVinci family. It integrates a C64x+ DSP core with clock rates up to 700 MHz (1.43 ns cycle time) and performance up to 5600 MIPS. The device features 32 KB L1 program memory/cache, 80 KB L1 data memory/cache, and 128 KB unified L2 RAM/cache. Core voltage is 1.05 V or 1.2 V depending on speed grade, with 1.8 V/3.3 V I/O. It includes a Video Processing Subsystem (VPSS), Ethernet MAC, DDR2 controller, and multiple serial interfaces. The ZDUL suffix indicates a 376-pin plastic BGA package (1.0 mm pitch) with low-power characteristics.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade (-L for low power) and package type (ZDU suffix denotes 376-pin plastic BGA). Confirm that the 1.05 V core voltage requirement aligns with the target system's power delivery design. Check for end-of-life status as this component series may be discontinued.

Digital Signal Processor Dsp Selection Notes

Select based on required processing throughput; higher clock speeds (up to 700 MHz) require stricter power supply regulation and thermal management. Ensure the application utilizes the 1.05 V core voltage option if available for the chosen speed grade to optimize power consumption. Verify pin multiplexing compatibility for required peripherals like EMAC or VLYNQ.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320DM643x Digital Media Processor family. It shares architectural similarities with the DM6435 and DM6437 but offers specific memory configurations and peripheral sets tailored for cost-effective digital media solutions. The ZDUL variant specifically targets low-power applications within the plastic BGA form factor.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacements within the same package are limited due to speed grade variations. Consider the TMS320DM6435 or TMS320DM6437 for functional equivalents, though memory sizes and peripheral counts may differ. Software migration guides are available for C64x to C64x+ transitions.
