HOUSTON Texas Instruments Inc. expects that a switch to 0.15-micron (L-effective) process technology will offer tighter packing densities and higher clock rates that will supercharge its TMS320C5000 product line. The process also allows more memory on each device, said C5000 marketing manager Mark Mattson.
The first product to use the process, the C5416, will clock at 160 MHz and include 128 kwords of SRAM, a 60 percent performance increase over existing devices like the C549 and C5410. The C5416 offers a 50 percent power reduction compared with the C5410, yet remains pin- and software-compatible (for both source-code and object-code programs). This lets the C5416 target midrange telecommunications applications such as voice-over-IP, fax and voice-mail servers, and PBX add-ons.
The new CMOS process, which has a drawn gate length of 0.18 micron, will be applied to other products in the C54X DSP line, including the C5402, the C549, the C5410 and the C5420. The C549 and C5410 will see a higher clock rate of 120 MHz, up from 100.
Samples of the improved C549 are available now, and production quantities will show up in the third quarter, Mattson said. Samples of the improved C5410 will be available in the third quarter and production quantities will be available before year's end.
