Overview

The DSP56364 supports digital audio applications requiring sound field processing, acoustic equalization, and other digital audio algorithms.

特性 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 × 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

• 1.5K × 24 Bit Y-Data RAM.

• 1K × 24 Bit X-Data RAM.

• 8K × 24 Bit Program ROM.

• 0.5K × 24 Bit Program RAM and 192 × 24 Bit Bootstrap ROM.

• 0.75K × 24 Bit from Y Data RAM can be switched to Program RAM resulting in up to 1.25K × 24 Bit of Program RAM.

Off-Chip Memory Expansion

• External Memory Expansion Port with 8-bit data bus.

• Off-chip expansion up to 2 × 16M × 8-bit word of Data/Program memory when using DRAM.

• Off-chip expansion up to 2 × 256k × 8-bit word of Data/Program memory when using SRAM.

• Simultaneous glueless interface to SRAM and DRAM

Peripheral Modules

• Enhanced Serial Audio Interface (ESAI): 6 serial lines, 4 selectable as receive or transmit and 2 transmit 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.
