TMS320DM355ZCEA135

Digital Signal Processor Dsp Overview

The TMS320DM355ZCEA135 is a Digital Media System-on-Chip (DMSoC) from Texas Instruments, featuring an ARM926EJ-S core operating at 135 MHz. It integrates an MPEG4/JPEG coprocessor supporting up to 720p encoding and JPEG processing at 50M pixels per second. The device includes a Video Processing Subsystem with hardware IPIPE for image processing and VPBE for display output. Memory resources consist of 16 KB instruction cache, 8 KB data cache, 32 KB RAM, and 8 KB ROM. It utilizes a 337-pin BGA package and operates with a 1.3 V core voltage and 1.8 V or 3.3 V I/O.

Digital Signal Processor Dsp Procurement Notes

Verify the suffix ZCE corresponds to the 337-pin BGA package and A135 indicates the 135 MHz speed grade. Confirm the device meets extended temperature requirements if applicable, as standard availability may vary by frequency rating. Ensure compatibility with required 1.8V or 3.3V I/O levels for the specific system design.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring integrated video encoding and decoding capabilities within a low-power footprint. The 135 MHz variant is suitable for standard definition or lower resolution high-definition tasks. Consider the available memory map and peripheral multiplexing when designing the board layout to ensure all necessary interfaces like USB and MMC/SD are accessible.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320DM35x family of DMSoCs. The ZCE suffix denotes the 337-pin LFBGA package with a 0.65 mm ball pitch. The A135 designation specifies the 135 MHz maximum clock rate version of the ARM926EJ-S core. Other variants in the family include higher clock speeds such as 216 MHz and 270 MHz.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the TMS320DM355, such as the 216 MHz or 270 MHz variants, provided software timing constraints are adjusted. Cross-family migration to newer DaVinci processors requires significant hardware and software redesign due to architectural differences.
