DM6446GB6C0121MV

Digital Signal Processor Dsp Overview

The DM6446GB6C0121MV is a Digital Media System-on-Chip (DMSoC) from Texas Instruments' DaVinci family, housed in a 361-NFBGA (16x16) package. It integrates a TMS320C64x+ DSP core operating at 594MHz and an ARM926JFS RISC core running at 297MHz. The device supports I/O voltages of 1.8V and 3.3V, with a core voltage of 1.20V. It includes 160kB of on-chip RAM and 8kB of ROM. Interfaces include ASP, EBI/EMI, Host Interface, I2C, SPI, UART, and USB. The component operates within a temperature range of 0°C to 85°C (TC) and is currently marked as obsolete.

Digital Signal Processor Dsp Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturing channels. Ensure compatibility with existing design infrastructure given the end-of-life status.

Digital Signal Processor Dsp Selection Notes

Select this part only if legacy support for the DaVinci DM644x series is required. The dual-core structure is optimized for tasks requiring simultaneous real-time signal processing and system control. Verify that the 361-NFBGA footprint matches the target PCB layout constraints.

Digital Signal Processor Dsp Part Context

The DM6446GB6C0121MV belongs to the TMS320DM644x series, specifically the DaVinci Digital Media System-on-Chip line. It shares architectural similarities with other variants like the DM6446ANB6C2127VC but differs in specific packaging and speed grade suffixes. It is designed to replace older single-core DSP solutions in complex multimedia applications.

Digital Signal Processor Dsp Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation due to the component's obsolete status. Designers may need to evaluate newer TI processors or third-party compatible SoCs with similar ARM/DSP hybrid architectures.
