Low power features include flexible PLL (with power-down mode) with dynamic clock switching, a hardwired CD ROM decoder, advanced 0.13 m CMOS process technology, 1.2 V core power supply, and on-chip 128K-byte SRAM. MP3 decode requires less than 20 MHz CPU bandwidth and runs from on-chip SRAM. For additional information regarding software drivers and applications, refer to
