TI TMS320C5504 and TMS320C5505 Digital Signal Processors

Texas Instruments (TI) introduced the TMS320C5504 and TMS320C5505 ultra-low-power digital signal processors (DSPs) at 150 MHz. The C5504 and C5505 DSPs offer the industry’s lowest total power at less than 0.15 mW/MHz and standby power at less than 0.15 mW. The processors feature up to 320 KB of on-chip memory, multiple integrated peripherals, dynamic voltage and frequency scaling. The TMS320C5504 DSP is priced at $6.20 in quantities of 1,000 units (1 ku). The TMS320C5505 is priced at $7.45 US in quantities of 1,000 units. Both devices are sampling now.
