Texas Instruments Inc. today will introduce two DSPs-one that integrates two identical processor cores on a single die, and a $5 chip that provides 100-mips performance.
Taking advantage of its 0.18-micron process technology, TI has added the TMS320C5420, which integrates two 100-mips DSP cores with 3.2 Mbits of
SRAM, to address high-end multichannel communicationsapplications. The TMS320C5402, which provides a $5 low-end solution, is being targeted at consumer-level communications products.
Both devices will be available in a 12 X 12-mm microStar BGA package, and operate at less than 60 mW active power per processor core.
"Driven by demanding applications like voice-over-Internet protocol, voice over frame relay, and 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," said Mark Mattson, TI's 'C5000 product marketing manager in Houston.
The devices are extensions of both the high and low ends of TI's most popular DSP family, the TMS320C54x, which is used extensively in communications applications.
The 'C5420 is expected to be used in arrays of processors, enabling customers to double the channel density of existing products or reduce their physical size, Mattson said. For instance, a telecom switch with 50 existing channels per board can be upgraded to more than 100 channels without increasing the size of the box, he said.
Samples of the 'C5420 are scheduled for availability in the fourth quarter, with production set for the second quarter of 1999. Samples of the 'C5402 are scheduled for the first quarter of 1999, with production set for the following quarter.
In addition to the MBGA package, the devices will be available in a 114-pin TQFP. In quantities of 50,000, the 'C5420 is priced at $55 and the 'C5402 at $5.
