Texas Instruments Inc. (TI) announced the lowest-power addition to its line of low-power DSPs. The new TMS320C5506 DSP operates at 108MHz and features 128KB of on-chip memory and a full-speed USB 2.0 interface.

Attributes of the C5506 that keep power consumption to a minimum include a 0.120mW standby power at 108MHz and 1.2V, very low core and memory operating power, dynamic frequency scaling, multiple standby modes that turn off individual peripherals and internal functions, and power optimisation tools to aid in low-power design.

In addition to the full-speed USB 2.0 port, the TMS320C5506 features three multi-channel buffered serial ports (MCBSPs), three timers, an I2C bus, a six-channel DMA, a 16-bit SDRAM interface, and 36 general-purpose I/O. The large number of I/O ports aid in peripheral device connectivity.

The TMS320C5506 is priced at Rs.265.71 ($5.75) in 10,000-unit quantities, and is available in a 12-by-12mm package. This chip targets touch screen controllers, USB headsets, cordless phones and hands-free car phone kits.
