DM355SDZCE135

Digital Signal Processor Dsp Overview

The DM355SDZCE135 is a digital media system-on-chip (DMSoC) from Texas Instruments' DaVinci family, featuring an ARM926EJ-S host processor and a C64x+ DSP core. It operates at a clock rate of 135 MHz. The device integrates 56 KB of on-chip RAM and 8 KB of ROM. It supports I/O voltages of 1.8V and 3.3V, with a core voltage of 1.30V. Packaged in a 337-ball LFBGA (13x13 mm) format, it includes interfaces such as ASP, I2C, SPI, UART, and USB. The component is designed for embedded digital video applications.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320DM3x series within the DaVinci architecture. It is a variant of the DM355S base product, distinguished by its specific clock speed and package suffix. The DM355SDZCE135 shares the same functional block diagram as other DM355 variants but is configured for 135 MHz operation.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacements may include other DM355 variants with different clock speeds (e.g., DM355SDZCE216). Verify that the target application can accommodate the reduced 135 MHz clock speed compared to higher-frequency counterparts. Ensure software binaries are compiled for the specific frequency configuration.
