DM355SZCE270

Digital Signal Processor Dsp Overview

The DM355SZCE270 is a digital media system-on-chip (DMSoC) from Texas Instruments, part of the TMS320DM3x Davinci series. It integrates a 216 MHz DSP and video processing hardware for MPEG-4/H.264 codecs. The device operates with a core voltage of 1.30V and I/O voltages of 1.8V/3.3V. It features 56KB on-chip RAM and 8KB ROM. Packaged in a 337-ball LFBGA (13x13 mm), it supports interfaces including ASP, I2C, SPI, UART, and USB. The component is rated for industrial temperatures between -40°C and 100°C.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'ZCE270' against official Texas Instruments documentation to confirm pin-to-pin compatibility and electrical characteristics relative to other DM355 variants. Confirm RoHS compliance status as manufacturing processes evolve. Check current product lifecycle status, as older DM355 models may be discontinued or subject to last-time buys. Ensure the 337-LFBGA package availability matches design requirements.

Digital Signal Processor Dsp Selection Notes

Select this model when a heterogeneous dual-core solution is required for real-time video processing. The 216 MHz DSP speed must meet algorithm complexity needs. Verify that the 1.30V core and 1.8V/3.3V I/O levels match the board's power rails. Consider the 337-ball BGA footprint for PCB layout constraints. Ensure sufficient external memory bandwidth if the internal 56KB RAM is insufficient for buffer requirements.

Digital Signal Processor Dsp Part Context

This component belongs to the Texas Instruments Davinci DM355 family, designed for low-power, high-performance digital media applications. It differs from general-purpose DSPs by integrating specialized video hardware engines. The 'DM355S' base number indicates the standard silicon revision, while 'ZCE' denotes the 337-ball LFBGA package and temperature range. The '270' suffix typically specifies speed grade or specific binning within the manufacturer's lineup.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-compatible replacements are limited due to the specific integration of TI's Davinci video engines. Alternative solutions may require redesigning the video interface logic. Review newer generations such as the DM365 or DM385 series for improved performance, though these often require schematic and software modifications.
