Overview The DSP56364 supports digital audio applications requiring sound field processing, acoustic equalization, and other digital audio algorithms. Features Digital Signal Processing Core • 100 Million Instructions Per Second (MIPS) with an 100 MHz clock at 3.3V. • Object Code Compatible with the 56000 core. • Data ALU with a 24 x 24 bit multiplier-accumulator and a 56-bit barrel shifter. 16-bit arithmetic support. • Program Control with position independent code support and instruction cache support. • Six-channel DMA controller. • PLL based clocking with a wide range of frequency multiplications (1 to 4096), predivider factors (1 to 16) and power saving clock divider (2i: i=0 to 7). Reduces clock noise. • Internal address tracing support and OnCE for Hardware/Software debugging. • JTAG port. • Very low-power CMOS design, fully static design with operating frequencies down to DC. • STOP and WAIT low-power standby modes. On-chip Memory Configuration • 1.5Kx24 Bit Y-Data RAM. • 1Kx24 Bit X-Data RAM. • 8Kx24 Bit Program ROM. • 0.5Kx24 Bit Program RAM and 192x24 Bit Bootstrap ROM. • 0.75Kx24 Bit from Y Data RAM can be switched to Program RAM resulting in up to 1.25Kx24 Bit of Program RAM. Peripheral modules • Enhanced Serial Audio Interface (ESAI): 6 serial lines, 4 selectable as receive or transmitt and 2 transmitt only, master or slave. I2S, Sony, AC97, network and other programmable protocols. Unused pins of ESAI may be used as GPIO lines. • Serial Host Interface (SHI): SPI and I2C protocols, 10-word receive FIFO, support for 8, 16 and 24-bit words. • Four dedicated GPIO lines. Packaging • 100-pin plastic TQFP package.
