Four new processors from Texas Instruments provide unmatched connectivity options and power-efficiency for smarter, greener industrial and communications products

TMS320C674x and OMAP-L138 feature SATA and universal parallel port (uPP) for high-capacity storage and high-speed data transfer

HOUSTON, June 29 /PRNewswire/ -- Connected, energy-efficient designs require high levels of peripheral integration, lower heat dissipation and longer battery life. To address this, Texas Instruments Incorporated (TI) (NYSE: TXN) today announced four new processors ( TMS320C6742, TMS320C6746, TMS320C6748 and OMAP-L138) with unmatched connectivity options and fixed- and floating-point capabilities that are also the industry's lowest power floating-point digital signal processors (DSPs). For more information:

Packed with a unique combination of application-tuned features and peripherals, these devices reduce overall system cost for a wide spectrum of products including industrial, communications, medical diagnostics and audio. For instance, power protection systems benefit from the OMAP-L138 device's fixed/floating-point DSP, ARM9, Ethernet MAC (EMAC) and LCD controller for up to $14 cost reduction compared to current solutions. For applications that need high-speed data transfer and high-capacity storage, such as test and measurement, public safety radios, music effects and intelligent occupancy sensors, the processors feature a universal parallel port (uPP) and are also the first TI devices with an integrated Serial Advanced Technology Attachment (SATA).

With performance levels up to 300 MHz, these products offer the ability to manage on-chip power through dynamic voltage and frequency scaling (DVFS) and multiple power down modes. When coupled with TI power management software and complementary analog solutions, developers can optimize their system for performance and power without having to be an energy expert. To ease and reduce development time, the new offerings are pin-for-pin compatible with each other, code compatible with all TMS320C6000(TM) devices and complemented by a low-cost experimenter board and full-featured evaluation module (EVM).

C6742, C6746 and C6748 DSP key features and benefits:

    --  Lowest-cost and lowest-power C6000(TM) processors and industry's
        lowest-power floating-point DSPs with 7mW of standby power at 1.0V/25
        degrees C and 420mW total power in use case scenarios
    --  Standby power up to nine times lower than existing floating-point DSP
        solutions on market
    --  First TI processor with an integrated SATA for high-capacity data
    --  A uPP enables high-speed connection to data converters, FPGAs or other
        C6742/C6746/C6748/ OMAP-L138 processors
    --  EMAC, multimedia card/secure digital (MMC/SD) and high-speed USB 2.0/1.1
        for desktop, network or portable connectivity or storage
    --  Video port interface provides the ability to input/output raw video
        while a LCD controller allows developers to easily connect video
        graphics array (VGA) resolution displays
    --  Multiple operating points facilitated through DVFS, powering off unused
        peripherals and selectable I/O voltages enable portability and reduce
        heat dissipation in products
    --  Complementary TI TPS65070 power management device implements all
        sequence and default options as well as supports the devices' power
    --  C674x core up to 300 MHz provides floating-point operations for
        high-precision and wide dynamic range as well as fixed-point operations
        for higher performance
    --  Pin-for-pin compatibility (C6742, C6746, C6748 and OMAP-L138) enables
        customer to expand their entire product portfolio using the same
        hardware and software platform
    --  128 KB to 448 KB on-chip memory to reduce external memory access and
        power usage

OMAP-L138 processor features and benefits:

    --  Dual-core processor that builds on the C6748 DSP with a 300 MHz ARM9
        gives developers the flexibility to add intuitive human machine
        interfaces, touch screens or networking capability to their applications
    --  ARM9 allows developers to implement high-level operating systems, such
        as Linux
    --  Windows(R) Embedded CE and Integrity(R) support is expected in 4Q09
    --  Low power usage with 440mW total power and 15mW in standby mode in use
        case scenarios

Development tools for varying levels of expertise:

    --  A community-supported $149 experimenter board is available from Logic,
        the designer and manufacturer. The board features the OMAP-L138
        system-on-module (SOM), 64 MB mDDR, open source Linux, DSP/BIOS(TM)
        drivers and can be used to develop on any of the four devices.
    --  An OMAP-L138/C6748 EVM from TI is available for those that need full
        peripheral access and TI support. The EVM builds on the experimenter
        board with an extra C6748 SOM, double the memory (128 MB mDDR) and full
        support for connectivity peripherals.

-- An OMAP-L138 (SOM) is a production-ready solution with 128 MB mDDR, power management and Ethernet PHY. It is available for less than $99 @ 10k EAU from Logic (

Pricing and availability

All processors are available for sampling and are priced as follows: TMX320C6742 for $6.70, TMX320C6746 for $13.50, TMX320C6748 for $15.20 and OMAP-L138 for $18.60 (1,000 units).

With an extensive portfolio of low power DSPs, including the lowest standby power DSPs from the C5000 portfolio to the ultra-low power microcontrollers, the lowest power floating-point DSPs and power management solutions in analog, TI continues to lead the market with innovative energy-efficient technology across its entire portfolio.

Review Article
  • TI Processors Suffer From Poor Documentation May 12, 2011
    Reviewed by 'dsp programmer'
    The following is the opinion of one software developer.
    TI makes feature rich DSPs. But buyer beware!
    The problems start when it is time to program the device. Despite filling several shelves, programmers can spend weeks learning the toolsets and searching out the missing details to accomplish routine tasks.
    The network development kit (NDK) presensts another caveat emptor. The NDK images are large. The manuals mention the possibility of omitting some components, but just try to find out to do it.
    The on chip boot loader does not support emac, and none is provided for SPI connected flash.
    Summing up, the C674x may be a great chip. But software documentation drops the ball, despite the page count. As a result, the schedule and cost risksm can be significant.
