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.
