World's Lowest Power DSPs from TI Double Performance and Eliminate the Price Barrier for Designers of Wireless and Wireline Communications Systems
At 200 million instructions per second (MIPs), the new TMS320C5420 with 200K words of random access memory (RAM), is the most highly-integrated, fixed-point DSP available, answering the high performance, low power consumption and small space needs of high-end, multi-channel infrastructure equipment such as base stations, remote access servers (RAS) modems and computer telephony systems. The new TMS320C5402, at $5 per 100 MIPS provides the industry's most cost-effective, general-purpose solution for single-channel, end-user terminal systems like wireless modems, next-generation personal digital assistants (PDAs), Ethernet phones and a variety of other telephony applications. These devices are well suited for both the infrastructure and terminal sides of the system, which allows designers to significantly reduce development time by maximizing code reuse for both ends of the system. "In recent years we've seen an acceleration of the much desired convergence of voice and data communications," said Mark Mattson, TI's 'C5000 product marketing manager. "Driven by demanding applications like voice-over Internet protocol (VOIP), voice-over frame relay (VOFR), video communications as well as higher data communications speeds, TI's newest DSPs can help merge voice and data communications, as well as support totally new portable applications in very small devices." "The 'C5420 is a perfect match of MIPS and on-chip RAM for our Fusion high-end IP telephony gateway products. The combination of our Alliance Generation resource management and the 'C5420's capabilities lets us provide universal telecommunications ports without the cost, power and heat requirements of additional RAM," said Brough Turner, senior vice president of technology for Natural MicroSystems. "Overall, the 'C5420 enables us to provide more channels per slot than is possible with any other technology." Using TI's 0.18-micron TImeline technology, the 'C5420 is able to pack into a tiny 12 x 12 x 1.4 mm microStar™ ball grid array (BGA) two DSP processing cores that are together capable of 200 MIPS, 200K words of on-chip SRAM memory and a complete complement of peripheral capabilities including six serial ports, a direct memory access (DMA) controller and a 16-bit host port interface (HPI). The 'C5420 also consumes as little as 0.32 milli-Amps per MIPS or less than 120 milli-Watts at 200 MIPS, making it the lowest power figure in the industry. The 'C5402 provides designers with a powerful and cost-effective solution. The 100 MIPS 'C5402 has 16K words of on-chip SRAM, 4K words of ROM and intelligent peripheral capabilities that includes two multi-channel buffered serial ports (McBSP), a bit I/O interface, a DMA controller and an independent HPI. The 58 milli-Watt power consumption of the 'C5402 makes it well suited to battery-powered portable systems like full-featured wireless and cordless telephones or new applications such as hands-free wireless communications devices the size of a hearing aid, Internet-protocol telephones and personal medical devices. The Lowest Power Consumption in the Industry The 'C5402 and 'C5420 continue the established 'C54x generation record of having the lowest power dissipation in the industry. The 'C54x DSPs achieve ultra-low power through a variety of methods, including one in which the chip turns on and off sections of the CPU transparently to the user. The high degree of integration, in part made possible by process breakthroughs like TI's TImeline technology, also contributes to lower power dissipation. With more integrated functionality and memory space for software algorithms and data, 'C54x DSPs conserve power by performing more operations on-chip rather than expending the significantly increased power that off-chip operations would require. The highly-efficient instruction set of the 'C54x generation also reduces power dissipation. Parallel instructions allow several operations to be executed concurrently on a 'C54x DSP, reducing the amount of power that would be consumed had the DSP executed multiple instructions consecutively to achieve the same end. Low power consumption is critical for applications at both the low and high ends of the performance spectrum. Many of the single-channel, end-user terminal systems that will be served by the 'C5402 operate off of portable batteries. Low power dissipation is imperative for prolonging battery life from hours to weeks for these systems. At the high end, where the performance capabilities of the 'C5420 are needed, multi-channel systems with highly dense circuitry often pack many DSPs in a small area. Low-power DSPs help assure the reliability of these systems by limiting the heat generated by the components and reducing the need for complex thermal dissipation schemes. Portable Software Code Software developed for any 'C54x processor can be easily migrated to any other DSP in the family. This provides tremendous development time-savings, and reduces maintenance and support headaches for original equipment manufacturers (OEMS) that supply a broad range of products and systems. For example, the cost-effective 'C5402 might be used in an OEM's web/IP phone while several powerful 'C5420s are used in that same OEM's high-end switching systems installed in a PBX or telecommunications carrier's central office (CO). It is likely that the same base-level software modules will be running on both the terminal and the infrastructure end-equipments. Support Tools to Shorten Development Cycles
As with all members of the 'C54x generation, the 'C5402 and 'C5420 are supported by a comprehensive selection of development tools. In addition to TI's standard suite of development tools, designers working with either the 'C5402 or the 'C5420 can download frequently used software modules today from the 'C5000 math and software library on the TI web site at Full Range of Supporting Analog and Mixed-Signal Technology
TI also offers the analog and mixed-signal componentry to complete a 'C54x system design. This includes data converters, analog front ends, codecs, voice band audio processors (VBAPs) and power management devices such as processor power supplies, voltage regulators and supply voltage supervisors. For more information on TI's analog and mixed-signal products and technologies, please visit Pricing and Availability For the 'C5420, samples are scheduled for availability in the fourth quarter of 1998 with production volumes expected in the second quarter of 1999. Samples of the 'C5402 are scheduled for availability in the first quarter of 1999 while volume production quantities are expected during the second quarter of 1999. In quantities of 50K, suggested resale pricing for the 'C5402 is $5.00 each and $55.00 each for the 'C5420. Both devices will be available from TI and its authorized distributors.
