TI adds low-cost
and high-integration DSP pair
Texas Instruments has unveiled the latest pair of programmable DSPs in its ultra-power-efficient TMS320C55x family of digital signal processors
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 the most highly integrated general-purpose DSP tailored to enable a new generation of Internet media entertainment appliances, personal medical, personal identification, security, digital still cameras, personal video cameras, or any combination of these applications.

The C5509 DSP has the most comprehensive set of onboard 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.
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 C5502 DSP continues TI's commitment to improve and expand the performance range of the TMS320CC55x 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 100MIPS at six cents per MIP and power dissipation of 0.6mW/MIP', said Christine Wu, C55x DSP product marketing manager.

'Today, the C5502 slashes that standard delivering up to four times the performance with 400MIPS and reducing cost per MIP to just 2.5 cents while requiring one-third less power at only 0.22mW/MIP.
The C5502 also delivers I/O bandwidth of more than 500Mbyte/s, while consuming less than 90mW of total power'.
The C5502 DSP is also the first DSP for less than $10 to provide a full 32bit external memory interface with bandwidth up to 400Mbyte/s and support for low-cost SDRAM.
It has 32Kword of on-chip dual-access RAM, a host port interface, general-purpose peripherals such as three 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 1Mbyte of SRAM and 1Mbyte of flash memory, as well as audio codec and power management circuitry.
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% over previous generation products.
Providing a complete system solution, the C5509 DSP has 96Kword of single-access SRAM, 32Kword of dual-access SRAM, 32Kword of ROM and six-channel DMA.
It also offers the widest selection of peripherals designers need including: an onboard USB 1.1 port; three multichannel buffered serial ports for full-duplex communication; a watchdog timer; a real-time clock with 32kHz crystal input and separate power supply; an on-chip 10bit ADC to enable battery monitoring and buttons interfaces; I2C interfaces to microcontrollers and codecs for inter-chip communication; and six-channel DMA supporting external transfers.
The C5509 DSP is the first device to have security features to protect intellectual property, including a 64bit device ID, secure ROM and disconnect options for JTAG access.
The C5509 DSP will initially be offered at 144MHz (up to 288MIPS) 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 Product briefs and datasheets for are available today for both the C5502 and C5509 DSPs.
Samples of the C5502 DSP will be available in the first quarter of 2002 with production in the third quarter of 2002.
Production price will be $9.95 (10,000-off).
The C5510 EVM is available for a limited time at $995 (a $500 savings) exclusively from TI.
Samples of the C5509 DSP will be available in June as well as the C5509 EVM (available from Spectrum Digital, a TI third party, for a limited time at $995).

Production will begin in the first quarter of 2002 at a price of $18 (10,000-off).
