TMS320DM355DZCE270

Digital Signal Processor Dsp Overview

The TMS320DM355DZCE270 is a Digital Media System-on-Chip (DMSoC) from Texas Instruments, featuring an ARM926EJ-S processor core operating at a maximum clock rate of 270 MHz. It integrates an MPEG4/JPEG coprocessor supporting up to 720p MPEG4 SP encoding and JPEG encoding at 50M pixels per second. The device includes a Video Processing Subsystem with hardware IPIPE and OSD capabilities. Memory resources consist of 16 KB instruction cache, 8 KB data cache, 32 KB RAM, and 8 KB ROM. Power specifications require a 1.3 V core voltage and support 1.8 V or 3.3 V I/O levels.

Digital Signal Processor Dsp Procurement Notes

Verify the ordering suffix 'A270' confirms the 270 MHz operational frequency and extended temperature range availability if required. Confirm package details match the 337-pin BGA (ZCE) specification. Check current production status as this component family may have discontinued variants.

Digital Signal Processor Dsp Selection Notes

Select this model when a 270 MHz ARM9 performance level is necessary for real-time video encoding. Ensure the system design accommodates the 1.3 V core supply and appropriate DDR2/mDDR memory interfaces. Verify that the 337-pin BGA footprint fits the PCB layout constraints.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320DM35x DMSoC family, which shares architectural similarities but differs in clock speeds and temperature ratings. The DZCE270 variant specifically denotes the highest clock speed option within the ZCE package configuration.

Digital Signal Processor Dsp Replacement Considerations

Consult official documentation for direct pin-compatible substitutes within the DM35x family, such as lower-frequency variants like the DM355DZCE216, ensuring software compatibility.
