DM355SZCE135

Digital Signal Processor Dsp Overview

The DM355SZCE135 is a digital media system-on-chip (DMSoC) from Texas Instruments' TMS320DM3x DaVinci series. It integrates a C674X DSP core operating at 135 MHz with a video processing subsystem capable of high-definition MPEG-4 encode/decode. The device features 56 KB of on-chip RAM and 8 KB of ROM. It operates with a 1.30 V core voltage and supports 1.8 V/3.3 V I/O levels. Packaged in a 337-ball LFBGA (13x13 mm) suitable for surface mount installation, it functions within a temperature range of -40°C to 100°C (tc).

Digital Signal Processor Dsp Feature Summary

• Supports HD MPEG-4 video encode and decode operations.
• Includes 56 KB on-chip RAM and 8 KB ROM for embedded applications.
• Offers multiple interfaces including ASP, I2C, SPI, UART, and USB.

Digital Signal Processor Dsp Applications

• High-definition video surveillance systems.
• Digital signage and display controllers.
• Portable multimedia players.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320DM3x family, specifically the DaVinci architecture designed for low-power video applications. The 'ZCE' suffix indicates the 337-ball BGA package, while '135' denotes the 135 MHz clock speed variant. It is distinct from higher-speed variants like the 216 MHz DM355 models.

Digital Signal Processor Dsp Replacement Considerations

Direct functional substitutes within the same package and pinout include other DM355 variants such as the DM355SZCEA216, provided the lower 135 MHz performance meets system requirements. Verify voltage levels and interface compatibility when cross-referencing with other DM3x series devices.
