TI's Two New Power-Efficient DSPs Enable Thousands Of Cost-Sensitive, Portable-Internet Products
- New Low-Cost DSP Sets Price-Performance Benchmark
- New Highly Integrated DSP Reduces System Size and Power by 3X for PC-Connected Applications
HOUSTON, (April 30, 2001) - Thousands of applications with demanding performance, size, cost and power budgets such as the coming generation of hand-held and Internet-enabled multimedia devices will be driven by two new code-compatible TMS320C5000(tm) digital signal processors (DSPs) unveiled today by Texas Instruments Incorporated (TI) (NYSE: TXN). The programmable DSPs are the second and third devices in TI's ultra power-efficient TMS320C55x(tm) DSP generation of products which set a new standard for power dissipation when it was introduced last year. See http://www.dspvillage.ti.com/c55xnewdspspr for more information.
The TMS320C5502 DSP, the new price-performance leader in TI's programmable TMS320C5000 DSP platform, meets the demanding cost and power budgets required by today's personal systems, with up to 400 million instructions per second (MIPS) of performance at $9.95 in 10,000 volume units.
The TMS320C5509 DSP is one of the most highly integrated general-purpose DSP tailored to enable a new generation of Internet media entertainment appliances, personal medical, personal identification, security, digital imaging appliances, personal video cameras, or any combination of these applications. The C5509 DSP has the most comprehensive set of on-board peripherals of any DSP, including a USB 1.1 port for direct connection to a PC or other USB host device. Its unparalleled functional integration allows designers of battery-operated and PC-connected products to reduce board space and power by a factor of three, while supporting most popular removable storage standards and multimedia format.
"TI continues to defend its leadership position with the announcement of these two new devices in their TMS320C55x™ generation of DSPs," said Will Strauss, president of DSP market watcher Forward Concepts. "The C5502 offers excellent performance at a very aggressive price while the C5509 probably has more features than any other DSP in the market today."
More Than Leading Edge Silicon
TI's DSP software and development tools give designers the ability to get to market faster and improve development success with easy to integrate products that optimize resources. Both the C5502 and C5509 DSPs are supported by TI's eXpressDSP™ Real-Time Software Technology, which includes the DSP/BIOS™ real-time kernel, the TMS320™ DSP Algorithm Standard, the Code Composer Studio™ Integrated Development Environment and interoperable software from the industry's largest third-party network.
The Price/Performance Leader for Digital Signal Processing
The C5502 DSP continues TI's commitment to improve and expand the performance range of the TMS320C55x DSP generation while reducing its cost and retaining code-compatibility with earlier members of the C5000 platform.
"In 1999, the C5402 set a new price/performance standard of 100 MIPS at six cents/MIP and power dissipation of 0.6 mW/MIP," said Christine Wu, C55x DSP product marketing manager. "Today, the C5502 slashes that standard delivering up to four times the performance with 400 MIPS and reducing cost/MIP to just 2.5 cents while requiring one-third less power at only 0.22 mW/MIP. The C5502 also delivers I/O bandwidth of more than 500 Mbytes/sec, while consuming less than 90 mW of total power."
The C5502 DSP is also the first DSP for less than $10 to provide a full 32-bit external memory interface with bandwidth up to 400 Mbytes/sec and support for low-cost SDRAM. It has 32 Kwords of on-chip Dual Access RAM, a Host Port Interface, general-purpose peripherals such as 3 Multichannel Buffered Serial Ports, a hardware UART, I2C master/slave port and 76 pins of dedicated and multiplexed GPIO.
The C5502 DSP is similar to the C5510 DSP released last year, so designers can begin code development immediately for the C5502 DSP on the C5510-evaluation module (EVM) available from TI. The PCI card-based C5510 EVM has 1 Mbyte of SRAM and 1 Mbyte of flash memory, as well as audio codec and power management circuitry.
A "System on A Chip" For Portable and PC-Connected and Multimedia Products
The C5509 DSP is the first DSP to combine the rich peripherals and power-efficient performance required by the next generation of hand-held, PC-connected, Internet-enabled products. The C5509 DSP reduces system power consumption, board space, parts count and manufacturing cost by performing functions typically requiring additional devices. The result approaches a "system on a chip" level, that allows the product it powers to offer more features in less space, with an increase in battery life of up to 70 percent over previous generation products.
Providing a complete system solution, the C5509 DSP has 96 Kwords of single-access SRAM, 32 Kwords of dual-access SRAM, 32 Kwords of ROM and six-channel DMA. It also offers the widest selection of peripherals designers need including:
- Onboard USB 1.1 port
- Three multi-channel buffered serial ports (McBSPs) for full-duplex communication
- Watchdog timer
- Real-time clock with 32-kHz crystal input and separate power supply
- On-chip 10-bit ADC to enable battery monitoring and buttons interfaces
- I2C interfaces to microcontrollers and codecs for inter-chip communication
- 6-Channel DMA supporting external transfers
- SDRAM, SBSRAM and Asyn Enhanced Memory IF
- Enhanced 16-bit Host Port Interface
- Two 16-bit general purpose timers
- Memory Stick Interface and MMC/SD
The C5509 DSP is the first device to have security features to protect intellectual property, including a 64-bit device ID, secure ROM and disconnect options for JTAG access. The C5509 DSP will initially be offered at 144MHz (up to 288 MIPS) and will be sampling at 200MHz (up to 400MIPS) in 1Q02.
The C5509 DSP supports most popular data storage formats, including Memory Stick, MultiMedia Card (MMC), and Secure Digital (SD). "For tomorrow's hand-held multimedia applications, TI's extensive third party network provides our customers off-the-shelf algorithms including MPEG4 and JPEG video encode and decode, MP3, WMA, and other audio encode and decode, voice recognition, text-to-speech, and biometrics," said Wu. "Development tools are available for the C5509 today, including evaluation modules and software, complete documentation, training and complementary analog components."
TI Offers Broad Portfolio of High Performance Analog Products to Support its DSPs
TI provides power management solutions that are designed with C55x DSPs in mind allowing designers to increase revenue by developing products that meet the market's needs. For portable applications, the TPS76915 ultra low power linear regulator requires only 17 uA of current and is available in the space saving SOT-23 package. To conserve battery life, the TPS61001 low input voltage boost converter enables up to 90 percent efficiency from single and dual cell batteries, and the power saving mode improves efficiency at light loads for longer battery life. TI also provides a variety of high performance data converters that easily interface with these new DSPs. For example, designers can use the multi-channel, 16-bit, 100ksps ADS8341 and ADS8344 analog-to-digital converters, and the multi-channel, 12-bit, 200ksps TLV2548 ADC. For higher resolution applications, the 24-bit ADS1252 delta-sigma analog-to-digital converter is available.
