TI touts package size for C54x DSP

Houston, Tex.– Texas Instruments new TMS320C5405 16-bit, fixed-point digital signal processor in a 7 x 7 mm package, is aimed at systems that require small size, low power consumption and affordability such as cellular phone attachments and hands-free kits, headsets and some hearing aids.

The C5405 DSP delivers up to 80 MMACs of real-time signal processing for about $5, some 360 times lower than competing devices, minimizing battery drainage when a system is idling, according to TI.

Based on the TMS320C54x DSP core, on-chip features include 32 Kbytes of RAM, two multi-channel buffered serial ports (McBSPs), an 8-bit host port interface (HPI) bus, two 16-bit timers and a six-channel DMA controller. The device has a footprint of just 49 mm2, compared with 144 mm2 for competing solutions — a 66 percent reduction of space. Additional space savings result from the chip's reduced number of I/O leads, requiring fewer board traces.

“As personal, portable electronics continue to shrink, package size and power consumption are becoming increasingly important,” said Raj Agrawala, TMS320C5000 product marketing manager, TI. “The C5405 answers these requirements, offering inexpensive DSP performance that helps TI customers create even smaller-scale, lighter-weight applications.”

Support for the C5405 DSP enables developers to begin creating their products right away. The device is code-compatible with other C54x DSPs, allowing developers to save engineering time by porting software from other systems. Compatibility enables developers to use the TMS320C5416 DSP starter kit (DSK), development platform that gives both experienced and novice designers an easy way to get started immediately with power-efficient product innovations. Application development can also be launched with the software-compatible TMS320C5402 evaluation module (EVM) from Spectrum Digital, which provides a cost-effective, standalone platform for hardware prototyping and algorithm debugging.

TI's C5405 DSP is sampling now, with volume production scheduled for the fourth quarter of 2004. The device is available in a 7 x 7 mm ball grid array (BGA). Planned pricing is $5.20 per unit in quantities of 10,000 units.
