TMS320DM355CZCEA21

Digital Signal Processor Dsp Overview

The TMS320DM355CZCEA21 is a Digital Media System-on-Chip (DMSoC) based on the ARM926EJ-S core, operating at 216 MHz. It integrates an MPEG4/JPEG coprocessor supporting up to 720p encoding and JPEG processing at 50M pixels per second. The device features a Video Processing Subsystem with hardware IPIPE and OSD capabilities. Memory includes 32 KB RAM, 8 KB ROM, and 16/8 KB caches. It utilizes a 337-pin BGA package (ZCE suffix) with 1.3 V core voltage and 1.8 V/3.3 V I/O options.

Digital Signal Processor Dsp Feature Summary

• Video Processing Subsystem with VPFE and VPBE
• USB 2.0 High-Speed PHY and dual MMC/SD interfaces

Digital Signal Processor Dsp Applications

• Digital still cameras
• IP security cameras
• Video door bells
• Digital photo frames

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix 'A21' against the manufacturer's current product status documentation. This suffix typically denotes the clock speed variant (216 MHz). Confirm that the ZCE package designation matches the required 337-pin BGA footprint and ball pitch specifications for the target PCB design.

Digital Signal Processor Dsp Selection Notes

Select this component when a fixed-function video codec is preferred over software-based DSP solutions to reduce CPU load. Ensure the system design accommodates the 1.3 V core supply and supports the necessary DDR2/mDDR memory interface. Verify that the 216 MHz performance meets the real-time processing requirements for the intended video resolution.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320DM35x family of DMSoCs from Texas Instruments. It shares architectural similarities with the DM350 but offers higher clock speeds and enhanced peripheral integration. The ZCE suffix specifically identifies the 337-ball BGA package configuration used in compact portable designs.

Digital Signal Processor Dsp Replacement Considerations

Consult the official TI product migration guide for verified substitutes within the DM35x family or newer DaVinci processors. Cross-reference pinouts and register compatibility if replacing with variants like the DM355L or DM365.
