TMS320DM355CZCE270

Digital Signal Processor Dsp Overview

The TMS320DM355CZCE270 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 capable of up to 50M pixels per second JPEG encoding and HD (720p) MPEG4 SP support. The device includes a Video Processing Subsystem with hardware IPIPE and OSD, along with interfaces for DDR2/mDDR SDRAM, USB 2.0, MMC/SD, and multiple serial ports. It utilizes a 337-pin BGA package and operates on a 1.3-V core voltage with 1.8-V or 3.3-V I/O.

Digital Signal Processor Dsp Procurement Notes

Verify the suffix 'A270' indicates the specific 270 MHz frequency variant within the DM355 family. Confirm the 'ZCE' package designation corresponds to the 337-pin Ball Grid Array with 0.65-mm pitch. Ensure compatibility with required 1.3-V core and 1.8-V/3.3-V I/O power supplies during system design.

Digital Signal Processor Dsp Selection Notes

Select this model when high-performance video processing at 720p resolution is required alongside ARM9 control capabilities. The 270 MHz speed option provides maximum throughput for complex image processing tasks. Verify that the 337-pin BGA footprint matches the PCB layout constraints and thermal requirements for the target application environment.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320DM35x series of Digital Media Systems-on-Chip. It shares architectural similarities with lower-frequency variants such as the 135-MHz and 216-MHz models, differing primarily in clock speed and potentially extended temperature range availability. The ZCE suffix specifically denotes the 337-pin BGA packaging used across the DM355 product line.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements include other TMS320DM355 variants with different clock speeds (e.g., TMS320DM355CZCE216). Software compatibility is maintained across the DM355 family due to identical instruction sets and peripheral configurations.
