Houston, Texas – Texas Instruments Incorporated (TI) announced today the lowest-power addition to its line of low-power digital signal processors (DSPs). The new TMS320C5506 DSP operates at 108 MHz and features 128 KB of on-chip memory and a full-speed USB 2.0 interface. It costs $5.75 in 10Ku quantities, and is available in a 12mm × 12mm package. The chip targets touch screen controllers, USB headsets, cordless phones and hands-free car phone kits, among other applications.
Attributes of the C5506 that keep power consumption to a minimum include:
- Very low standby power (0.120 mW at 108 MHz and 1.2 V)
- Very low core and memory operating power (for example, 58 mW at 108 MHz)
- Dynamic frequency scaling
- Multiple standby modes that turn off individual peripherals and internal functions
- 128 KB of SRAM for efficient code fit and minimal off-chip memory access
- Power optimization 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.
Developers using the C5506 DSP can leverage the TMS320C55x Power Optimization DSP Starter Kit (DSK). Among its features, the DSK includes:
- Power planning tools that allow developers to estimate power consumption for various memory and peripheral combinations.
- Power Manager in DSP/BIOS kernel, a software module that enables developers to implement power saving strategies at an operating system level.
- Power Scaling Library to support dynamic control of run-time core frequency.
- LabView-based Power Measurement Tool from National Instruments, providing profiling of power consumption based on actual application behavior.
