DaVinci TMS320DM6437, TMS320DM6435, TMS320DM6433 and TMS320DM6431 Low Cost DSP Chips For Video and Automotive Applications

Texas Instruments announced  four new DaVinci TMS320DM643x processors, optimized for cost-sensitive (Priced as low as $9.95) digital media applications and include special features that make them suitable for automotive vision applications such as lane departure and collision avoidance as well as machine-vision systems, robotics, video security and video telephony. TMS320DM6437, TMS320DM6435, TMS320DM6433 and TMS320DM6431 processors feature the new video-optimized programmable TMS320C64x+™ DSP core plus video, memory and network interfaces.

Features of the TMS320DM643x processors

• Improved video performance.
• The new TMS320C64x+™ core operates at up to 600 MHz.
• 80 KB L1D, 32 KB L1P cache/SRAM and 128 KI L2 cache SRAM memory
• Two 32-bit, 133-MHz extended memory interfaces (EMIFs)
• 10/100 Ethernet media access controller (MAC), two UARTs, I2C, SPI, GPIO, McASP and three PWMs
• Available in 16-mm or 23-mm pin-compatible square packages

The addition of a video processing subsystem (VPSS), provides up to a 40 percent performance lift. The integration of up to four DACs reduce the system bill of materials by up to $4. For many applications, the TMS320DM6437, TMS320DM6435, TMS320DM6433 and TMS320DM6431 will have enough headroom for networking, user interface and other tasks required to run the complete system on the DSP.

TMS320DM6431, TMS320DM6435 and TMS320DM6437 are suitable for automotive vision applications, such as lane departure warning and collision avoidance. They support the CAN (controller area network) bus interface, a standard in the automotive industry.

The four DM643x processors take full advantage of the DaVinci software and development infrastructure by allowing designers to focus on the application functionality. Developers are able to implement video, imaging, speech and audio technology through simple calls to the DaVinci application programming interface (API) that manages the implementation of specific codec engines and matching screen resolution. For example, the developer can use a simple function call without being concerned with the details of the actual codec implementation. The DM643x devices can also be programmed using conventional DSP programming methods with TI’s best-in-class eXpressDSP™ software and development tools, including Code Composer Studio™ Integrated Development Environment.

Samples are available today and devices will be in volume production in 2Q 2007, priced from $9.95 to $22.95 in 10,000 units. A complete, robust digital video development platform that leverages the entire DaVinci technology ecosystem, including the codec engine, eXpressDSP™ Data Visualization Technology and digital media software for the DM643x devices will be released in 2Q 2007.
